Heat transfer, fluid flow and entropy generation due to combined buoyancy and thermocapillary forces in a 3D differentially heated enclosure containing Al2O3 nanofluid are carried out for different Marangoni numbers and different nanoparticles concentrations. The vector potential-vorticity formalism and the finite volume method are used respectively to formulate and to solve the governing equations and calculations were performed for Marangoni number from −103 to 103, volume fraction of nanoparticles from 0 to 0.2 and for a fixed Rayleigh number at 105. An intensification of the flow and an increase in heat transfer and of total entropy generation occur with the increase in nanoparticles volume fraction for all Marangoni numbers

Natural convection and entropy generation due to the heat transfer and fluid friction irreversibilities in a three-dimensional cubical cavity with partially heated and cooled vertical walls has been investigated numerically using the finite volume method. Four different arrangements of partially active vertical sidewalls of the cubical cavity are considered. Numerical calculations are carried out for Rayleigh numbers from (103 ≤ Ra ≤ 106), various locations of the partial heating and cooling vertical sidewalls, while the Prandtl number of air is considered constant as Pr=0.7) and the irreversibility coefficient is taken as (φ=10−4). The results explain that the total entropy generation rate increases when the Rayleigh number increases. While, the Bejan number decreases as the Rayleigh number increases. Also, it is found that the arrangements of heating and cooling regions have a significant effect on the fluid flow and heat transfer characteristics of natural convection and entropy generation in a cubical cavity. The Middle-Middle arrangement produces higher values of average Nusselt numbers

Risk Matrix for Delay Causes in Construction Projects in Saudi Arabia

Time performance of a project is usually a particularly important consideration for the construction parties. Often, the most troublesome construction disputes involve delay and failure to complete the work in the specified time frame. Many variables have an impact upon construction delay in Saudi Arabia. This study aims at identifying the risk matrix for delay causes in construction projects in Saudi Arabia from consultants’ viewpoint. A questionnaire survey was undertaken of 51 consultants working on construction projects in the Northern Province of Saudi Arabia. Thirty five delay causes were identified through literature review. The study concluded that the top delay causes in construction projects in Saudi Arabia from consultants’ perspective are: bid award for lowest price, changes in material types and specifications during construction, contract management, duration of contract period, fluctuation of prices of materials, frequent changes in design, improper planning, inflationary pressure, lack of adequate manpower, long period between design and time of implementation, payments delay, poor labor productivity and rework.

Construction firms work in a harsh competitive environment where every company struggles to ensure that its projects are successfully completed with the constraints of best quality, cost and time. Quality management systems (QMS) have been widely used by world-class construction companies to ensure successful projects delivery. The main purpose of the present study is to evaluate the degree of readiness of Saudi construction firms operating in Hail region towards the implementation of QMS and the proper use of quality tools. The perception of both managerial and technical staff about QMS and quality tools is investigated and analysed. Based on previous research dealing with QMS and quality tools implementation in the construction industry, a comprehensive survey tool is designed and conducted. Results show a high degree of misunderstanding of QMS strategies, tools and techniques in the surveyed construction firms. The study indicates that organizational culture represents a real barrier impeding the implementation of QMS and quality tools in the Saudi construction sector.
