Dumpers or dump trucks are used all over the world to move overburden from many opencast mines. Diesel engines are the main driving force behind the trucks. The frequency of damage due to the failure of diesel engines is enormous. Therefore, efforts are necessary to analyze failure to reduce the downtime periods. A detailed analysis of engine failure at the subsystem level needs to be done. Reliability analysis and maintenance planning remain the norm in this regard. The obstacle faced while analysing the reliability of dumpers was the availability of a large number of data failures. In this paper, this issue is addressed by using Common Beta Hypothesis test and Meta-analysis test. The engine is divided into five subsystems. The result shows that all five subsystems pass the CBH test and Meta-analysis test. Accordingly, the failure data is grouped. The trend test of grouped failure data shows that the Failure data of two subsystems follows the independent and identically distributed characteristics while the remaining three do not follow it. The reliability is estimated for all five subsystems. Finally, fuel supply subsystems show the highest reliability while the lowest value is seen for self-starting subsystems.

Rising greenhouse gas emission and global warming compel the world community to look for renewable energy sources to generate power. The renewable wind energy provides an alternative to fossil fuel. A significant research attention has been placed on the use of vertical axis wind turbine due to its low-wind operational capability. However, the effectiveness of traditional vertical axis wind turbines (VAWT) in built-up areas is below expectation. Therefore, the primary objective of this study is to develop a single stage drag-based multi-blade micro vertical axis wind turbine which can generate a reasonable amount of torque and power in complex wind conditions in built-up areas.

The clean-energy demand for industrial and socio-economic development necessitates developing countries to seek nuclear energy/technology for power generation to supplement and reduce their absolute dependency on fossil fuel. However, the lack of skilled manpower is one of the main constraints to achieve this goal. Moreover, the lack of nuclear experience, knowledge, educational infrastructures and resources is another constraint for developing skilled human resources for the safe use of nuclear technology in emerging countries. This paper discusses the recent trend in worldwide nuclear energy plant growth in the developing countries and the need for qualified manpower development programs for viable nuclear energy plant design, construction, operation, maintenance, se-cured repair and cost effective use. The paper also enlightens the nuclear engineering education in South Asia.

Inadequate power generation and supply are considered to be the main hindrance of economic development and prosperity in South Asia. Limited indigenous energy resource of each South Asian nation is not suitable to generate sufficient power. Moreover, the availability of limited indigenous energy resources differs among South Asian nations. The power demand and power generation capacity notably vary among the countries due to seasonal variability. This paper highlights the need for a collective effort to develop mechanism for the utilisation of limited resources and enhance the cross-border power trade among South Asian nations. Bilateral and multi-lateral cooperation will allow overcoming regional power shortage and augmenting collective energy security.

Nine soccer balls were tested for their friction against a leather sheet, using a force plate. An average normal force of 63.6 N was applied and the movement of the ball had an average velocity of 15 mm/s. Each test was repeated 15 times and the average Coefficient of Friction (COF) was reported. The following results were obtained: Jabulani (COF: 0.62 ± 0.05); Fracas (COF: 0.41 ± 0.01); Ordem 3 (COF: 0.63 ± 0.02); Teamgeist (COF: 0.38 ± 0.01); Brazuca (COF: 0.45 ± 0.01); Kopanya (COF: 0.39 ± 0.01); React (COF: 0.37 ± 0.01); Finale 15 (COF: 0.39 ± 0.06); Vintage T-panel leather ball (COF: 0.41 ± 0.02). Overall, the COF of all balls tested ranged between 0.37 and 0.62. The Finale 15 ball showed a decreasing COF trend with repeated trials and the React ball produced pronounced slip-stick phenomenon.

The paper describes flow control techniques viz. vane-type vortex generator (VG) array and rear-spoiler on its trunk (boot) side used to reduce drag of a passenger car. The experimental and computational studies were carried out and different cases and combinations were analyzed for the car model by varying incoming airflow angle and spoiler angle and orientations of VG array to find out the optimum conditions for which drag coefficient is found minimum. Shear stress transport (SST) k-w turbulence model is found suitable in predicting the multi-scale rear-wake vortices of the car geometry. It is found that the crossflow increases the drag coefficient, which can however be reduced effectively if both VG array and rear-spoiler are used. Parametric analysis shows that counter-rotating VG array is found useful in reducing drag (around 23 %) as it promotes better flow mixing at its downstream, which is helpful in avoiding flow separation. The finding is also supported by the flow visualization study. It is also found that saving up to 11.5 % in the fuel consumption can be achieved by reducing drag using these techniques. The wake analysis and turbulent kinetic energy plots indicated that the counterrotating VG array while used with a rear spoiler parallel to the flow reduced drag considerably.

This paper examines the how the South Asian countries are addressing their energy deficiency as the capacity to refine imported crude oil is limited except India. India has developed substantial refining capacity (247.6 million tons per annum) compared to Pakistan (18.8 mtpa) and Bangladesh (1.5 mtpa). India’s refining capacity is being currently utilized nearly 100%. Having no local refining capacity, Nepal and Bhutan import refined petroleum products entirely mainly from India. The demand for refined petroleum products in Bangladesh outstripped the quantity produced by the country’s single aged oil refinery over 3 times. Similar problem is faced by Pakistan. This paper provides an analytical framework based on the data collected from the region and argues that a regional energy trade will create a mutually beneficial platform for effective utilisation of natural resources which will increase reliability of power supply, build economies of scale, enable mutual support during contingencies, transform sectors on a large scale and contribute to economic growth. This trading platform will promote market integration in energy (oil, gas coal) and energy-related goods and services.

The teaching and learning of engineering courses are always challenging due to its complex and abstract nature, and the mathematics involved. With diminishing resources (e.g., continuous funding cut, frequent professional/academic staff career movement, lack of competent professional staff, inadequate laboratory infrastructures), teaching and learning of engineering courses become harder and it is progressively becoming difficult to teach basic engineering courses effectively. As a result, students cannot achieve effective learning outcomes. To overcome these challenges, a three-step teaching approach has been developed to enhance students’ learning outcomes. This approach is cost effective, user-friendly and attractive. The method comprises a real laboratory demonstration video clip, conduction of a real laboratory experiment and a computer simulation/modelling. The developed three-step teaching and learning approach can be applied to any engineering courses.

In Saudi Arabia, the current production of electric power is mainly relying on crude oil which causes a high percentage of carbon dioxide emissions and no power is generated from any renewable sources. However, recently Saudi Government has announced a development plan ‘The Saudi Vision 2030’ where the target is 20% of the production of power from the renewable sources mainly from solar and wind. Like other countries e.g., China, India, US and UK that produce a significant amount of their electric power from renewable sources. Saudi Arabia has a vast land area where there is a plenty of prospect to install renewable power plants (solar and wind farm) to generate a significant amount of electric power to meet their 2030 target. This paper analyses past 10 years wind data in various location of Saudi Arabia to investigate the feasibility to generate power. This study also recommends the potential locations that are suitable for wind power generation including suggestions of the wind turbine specifications.

Economic prosperity and development in South Asia are significantly restricted by the insufficient power supply. Inadequate indigenous energy resource of each South Asian nation is not enough to generate power for meeting the growing demand. Moreover, the availability of limited indigenous energy resources differs from one country to another in South Asia. In addition to availability variation of indigenous energy sources, the climate conditions also vary resulting in variable power demand and power generation capacity. This paper reviews the current power generation capacity of all eight nations of South Asia. It highlights the bilateral and multilateral collaboration opportunities in power generation and the need for cross boarder power trade among South Asian nations. The review emphasises that the bilateral and multi-lateral cooperation will allow overcoming regional power shortage and augmenting collective energy security, economic and political integration.

Rapid expansion of nuclear technologies and nuclear energy for power generation in emerging (developing) countries necessitate undertaking urgent skills development programs. Skilled human resource is a vital first step in ensuring a sustainable supply of qualified/competent personnel for the safe, responsible and sustainable use of nuclear technologies. This paper highlights the current trend of global nuclear power plant development in new comer countries. It also emphasis the need for skilled human resource development programs that are required for sustainable management of nuclear power plants during construction, operation, maintenance and repair for the safe and secure operation. The national skills development program of a nuclear ambitious country must include human resource development, education and training, knowledge management, and knowledge networks at the national, regional and international level.

The global consumption of natural gas is expected to increase at an average of 1.6% over the next 5 years from 3.7 trillion cubic meter (tcm) used in 2017. Although the current use of gas in power generation is dominant followed by industry, residential and other sectors during 2011-2017, the global industry is expected to be the main driver for gas consumption followed by power generation, residential and commercial and other sectors by 2023. Many countries including Bangladesh use natural gas primarily for power generation. Among the main reason was energy security, availability of smooth supply of own relatively cheaper natural gas. As the demand for power has increased and the country could not extract indigenous discovered coal due to complex mine water management and agricultural land rehabilitation, its indigenous fuel supply restricted utilizing installed capacity of power generation, impeding industrial growth and development. This paper reviews the status of natural gas in Bangladesh and the engagements of local and international oil companies in natural gas exploration. The paper highlights the need for transboundary gas importation and associated infrastructure to support its development activities. It is recommended that the indigenous and transboundary gas to be managed efficiently and a long-term strategy for sustained supply of fuel from multiple sources to be formulated to maximise the energy security and achieving Bangladesh Vision 2041.

A boxfish has certain aero/hydrodynamic features in its body shape which makes it more efficient in traveling through the water using less energy. Because of the streamline features of the boxfish, it produces less drag for its movement. So, there is a lot of possibility to design a passenger car by implementing the aerodynamic features on the car shape for improving the energy efficiency. This paper investigates the aerodynamic behavior of a boxfish using both experimental and computational methods. A scaled-up model boxfish was manufactured, and passenger car model was also developed by applied certain aerodynamic features on the car shape and a prototype was manufactured. The models were tested in a wind tunnel condition. The results indicate that the drag coefficient of a boxfish is around 0.24 which is significantly lower than current drag coefficient of a passenger car. The car design inspired by boxfish also energy efficient than a commercially manufactured passenger car. Hence, a boxfish shape can be adapted for achieving low drag and energy efficient motor vehicle design.

Bridge pier are the most widely used hydraulics structures in ocean, offshore and river engineering. As a result, scour around bridge pier, flow prediction and it interaction are widely attracted by the civil, mechanical and marine engineers. The local scour around the piers of the bridge is one of the main causes of the bridge failure. The local scour of river water is a catastrophic effect on the engineering structures. It leaves them under dangerous, maintenance prone conditions and occasionally leads to loss of life. The damage to the hydraulic and civil structure due to local scour is a global problem and has been studied experimentally and numerically by many researchers for several decades. In this paper, local scour around bridge piers as a complex phenomenon has been explained and the problem to countermeasure the local scour effect. In past two decade computer simulations have been developed for bridge pier scouring. They have an advantage of being able to simulate a situation at full scale scenario, and can easily alter the geometry as required. Early CFD simulations were mainly focused on single-phase model which require empirical sediment transport equations to predict sand motion. Multiphase CFD simulation models are a most recent development; they model sediment transport as a granular flow to predict the sand movement and analyse the scour depth. The experimental validation will be undertaken using generic water tunnel. A series of scale models will be developed in the future as per the geometric characteristic of CFD models.

Currently biofuel production from microalgal biomass is less attractive due to cost consideration despite having enormous potential. Researchers are increasingly focusing on, among others, the best utilisation of microalgal bioproducts to make biofuel production commercially viable. As freshwater and marine algae live in various environmental conditions, they develop special defense mechanisms to survive by producing a wide range of chemical compounds in their body. These chemical compounds are the commercial sources of various high-value bioproducts that can be used for health and other benefits. Although most publications have focused on biofuel production from microalgae, scant information is available on microalgal bioproducts and their applications in the open literature. Therefore, the primary objective of this article is to review the existing and potential high value bioproducts (other than biofuels) from microalgae and their current industrial applications. The review summarises microalgal bioproducts and their current uses in nutraceuticals, cosmeceuticals, pharmaceuticals, aquatic and terrestrial animal husbandry, food industry etc. to make biofuel production more commercially viable.

Aero/hydrodynamics plays a vital role in speed sports (athletes, athletes’ outfits, sports balls, sports equipment, etc.). Sports balls (spherical - golf, cricket, tennis, soccer, baseball, softball, etc. and oval shape - rugby, American football, Australian football), sports garments (swimsuits, ski jumping & alpine skiing suits, cycling skin suits, skating suits) are affected by aerodynamic and hydrodynamic behavior of fluids (air and liquids). The aero/hydrodynamics dictates the curved flight path of a soccer, tennis, cricket, baseball or golf ball and the course of a surfboard and sailboat through water. It affects speed, motion (position and placement) and ultimately athlete’s performance. Ignoring the effect of aerodynamic and hydrodynamics, it is almost impossible to achieve the desired success in any competitive speed sports. Due to stiff competition, the outcome of most sports aero/hydrodynamics research work undertaken by commercial organizations as well as individual sports teams/organizations are kept in-house, and scant information is available in the public domain. The RMIT University’s Sports Aerodynamics Research Group has been active in aerodynamics and hydrodynamics research related to some popular speed sports. This paper highlights some research work on sports aerodynamics and hydrodynamics undertaken at RMIT University

Rising energy cost and declining technology cost particularly household batteries has seen a rise in demand for small scale renewable energy sources. There have been reports of doubling of grid-connected solar panels with battery storage from 1568 to 4356 units in 2017. Therefore, this paper aims to provide a design and economic feasibility study of a hybrid power generation for coastal area in Geraldton, Australia. A photovoltaic panel and wind hybrid system were considered. Calculations were performed to design two different systems and their respective components. An economic analysis was also performed to determine the total cost of the systems over a 20-year period. Study indicates that properly designed hybrid system can be an effective means of partially (50%) fulfilling power demand. A total of ten 280 W photovoltaic panels and one 1 kW wind turbine is sufficient to provide 110% of the summer demand and 85% of the winter demand.

Local scour around bridge piers is one of the main causes of bridge failures. Study of local scour is very significant for the safe design of piers and other civil and marine structures. Despite the subject has been explored for many decades, the numerical developments have been very limited due to the complicated interaction of three-dimensional flow, sediment transport and fluid-particle interaction. In this work, a numerical model based upon the Reynolds Average Navier Stokes Equation (k-ε) approach has been used for predicting the three dimensional flow (3D) around a bridge piers (square and cylinder piers), mounted on a flat and fixed bed. The main aim of this paper is the validation of the numerical model, based upon the previous experimental data. The CFD-numerical tool is proficient to qualitatively reproduce the flow characteristic for different pier shape and features around the pier, such as the upstream vortex (horseshoe vortex) and downstream vortex (vortex shedding in the wake). The outcome of this study can be used developing adequate numerical model to simulate the 2D and 3D turbulent flow past the square and circular piers, which are relevant case-studies for the marine and civil structures supported by pillars. The corresponding numerical results are in good agreement with those extracted from available experimental data.
