The multi-phase Rayleigh–Bènard convection has been weakly investigated, even though it plays a leading role in the theoretical and applied physics of the heat transfer enhancement. For the case of moderate turbulent convection, a rather unexpected result is an unusual kind of wind reversal, in the sense that the fluid is found to be strongly influenced by the bubbles, whereas the bubbles themselves appear to be little affected by the fluid, despite the relative smallness of the Stokes numbers. The wind reversal induced by the bubbles dispersed in the fluid is a new and remarkable phenomenon in multi-phase flows that provides further perspectives in understanding the complex physics leading the enhancement of thermal convection. For this reason, the fundamental research proposed in this paper aimed to identify a space of control parameters and the physical mechanisms responsible for the wind reversal induced by dispersed bubbles in a confined convective flow. The strength of the following description lies in an innovative numerical approach, based on the multi-scale physics induced by the coupling of the local thermal and mechanical mechanisms arising between each bubble and the surrounding fluid. The continuous phase has been solved numerically using the direct numerical simulation (DNS) technique and each bubble has been tracked by means of a particle Lagrangian model.

The problem of water leaks in the water distributions networks is faced through a continuous monitoring of the network infrastructures, performed using smart sensors appropriately placed on opportune pipes of the net. The methodology proposed by the authors for detecting leaks and locating them with sufficient accuracy, consists in measuring the radial vibrational status of opportune pipes of the network. The idea arises from the consideration that the variation of the energy transmitted to the pipe walls by the radial component of the vibrations induced by the turbulence of the fluid onto them may be related to the flow leak itself. The structure of the proposed Smart Water Grid (SWG) is described here and a monitoring procedure is formulated starting from the innovative leak detection technique; a loss index is introduced and the first experimental results of the measurement campaign, performed on a specially designed and built test simple network, are here presented.

Differential pressure flowmeters are commonly used in industrial applications where, however, the upstream flow conditions are usually highly disturbed, caused by the presence, in the network pipe, of elbows, valves, etc. To achieve accurate flow measurements, the use of the cone meter is recommended as the flowmeter has the property to normalize the flow both upstream and downstream. In this paper, the authors present a cone flowmeter of new geometry that allows them to obtain better performance with respect to the original one; in particular, it provides a higher discharge coefficient (Cd) for a wider range of operating conditions.

This paper illustrates an innovative algorithm for the detection and localization of partial detachment defects affecting thermal barrier coatings (TBCs), using the Long Pulsed Thermography (LPT). The scientific literature offers many applications, proving the LPT effectiveness in providing clear and intelligible thermal image contrasts. The proposed post processing technique directly operates on the raw thermograms acquired from the specimen surface. The algorithm aims at improving the polynomial fit of the logarithmic time history of the surface temperature during the cooling stage. The enhancements consist of the introduction of additional parameters, such as the fit zero-intercept and its standard deviation whose efficiencies are compared with the already exploited fit slope and determination coefficient ones. The considered parameters, called damage classifiers, are set in image maps from which the possible defects are deducted.

In the smart industry philosophy, continuous monitoring of the machinery condition is crucial to follow up the decision-making strategy. In this context, the purpose of the paper is to elaborate a simple procedure aimed at rotating machine condition monitoring and prognosis. The general assessment of the machine operating condition goodness is indeed crucial for a smart and efficient industrial processes running. Any incipient defect manifests itself in an alteration of the component vibratory status. The proposed procedure is based on the continuous monitoring of the energetic features of the vibration signals acquired from the equipment under analysis. The considered parameter is the vibration velocity RMS value. It is representative of the amount of the fatigue stress affecting the machine. By means of a continuous monitoring of such energetic features, the user is able to plan the maintenance of the equipment, prior to impeding failures. The case study provided in this paper, can illustrate how the data from a monitored process can lead to the machine system self-awareness and, eventually, self-maintenance. Such an approach allows for a self-assessment of health and degradation status of the machine system, in the framework of the Industry 4.0 scenario, one of the pillars of the Smart City.

Pipelines conveying fluids are considered strategic infrastructures to be protected and maintained. They generally serve for transportation of important fluids such as drinkable water, waste water, oil, gas, chemicals, etc. Monitoring and continuous testing, especially on-line, are necessary to assess the condition of pipelines. The paper presents findings related to a comparison between two spectral response algorithms based on the decimated signal diagonalization (DSD) and decimated Padé approximant (DPA) techniques that allow to one to process signals delivered by pressure sensors mounted on an experimental pipeline.

Studies dating almost a century relate clay properties with the structure of the diffuse double layer (DDL), where the charged surfaces of clay crystal behave like an electric capacitor, whose dielectric is the interstitial fluid. The intensity of the inner electric field relates to the concentration and type of ions in the DDL. Other important implications of the model are less stressed: this part of the clay soil system, energetically speaking, is conservative. External contribution of energy, work of overburden or sun driven capillarity and long exposure to border low salinity waters can modify the concentration of pore-waters, thus affecting the DDL geometry, with electric field and energy storage variations. The study of clay soils coming from various natural geomorphological and hydrogeological contexts, determining a different salinity of interacting groundwater, shows how the clay interaction with freely circulating waters at the boundaries produces alterations in the native pore water salinity, and, at the nano-scale, variations of electric field and stored energy from external work. The swelling and the shrinkage of clay soil with their volumetric and geotechnical implications should be regarded as variations of the electrostatic and mechanical energy of the system. The study is based on tests on natural clay soil samples coming from a formation of stiff blue clays, widespread in southern Italy. Geotechnical identification and oedometer tests have been performed, and pore waters squeezed out from the specimens have been analyzed. Tested samples have similar grain size, clay fraction and plasticity; sorted according to the classified geomorphological/hydrogeological contexts, they highlight good correlations among dry density, mechanical work performed in selected stages of the oedometric test, swelling and non-swelling behaviour, and electrical conductivity of the squeezed pore waters. The work performed for swelling and non-swelling samples shows well-defined differences; this endorse the relevance of pore-water salinity in determining the volumetric state of clay soils under overburden and specific hydrogeological border conditions, which together define a specific energetic state.

Highlights•Simplified procedure for measuring fluid flow rate in square cross-section pipes and turbulent flow.•Simpler and faster evaluations than EN 12599 standards.•Individuation of a single point in the cross-section where the flow velocity is directly measured.•Model validation by means of LDA instrumentation in wind tunnel. AbstractThe main purpose of the paper is to provide a simplified measuring procedure for evaluating the fluid flow rate in square cross section pipes. This procedure consists in directly measuring the flow (mean) velocity at a fixed location in the section. To this aim, an extension of the methodology utilized for circular section pipes is here proposed. The method simplifies and improves the procedure suggested by the technical standard EN 12599. It has been possible to locate a specific position in the cross section where to measure the mean flow velocity in order to evaluate the flow rate. Here, it is shown that the proposed methodology allows the estimation of the flow rate with higher accuracy than the normed one does, estimating errors less than those accepted in common practice. The effectiveness of the proposed method has been proved by means of a series of experimental tests performed in a wind tunnel, using a Laser Doppler Anemometer (LDA) in order to measure the punctual velocities in the test cross-section of the tunnel in order to reconstruct the velocity profiles useful to determine the fluid flow rate.

The paper is a review on the worst case uncertainty (WCU) concept, neglected in the Guide to the Expression of Uncertainty in Measurements (GUM), but necessary for a correct uncertainty assessment in a number of practical cases involving distribution with compact support. First, it is highlighted that the knowledge of the WCU is necessary to choose a sensible coverage factor, associated to a sensible coverage probability: the Maximum Acceptable Coverage Factor (MACF) is introduced as a convenient index to guide this choice. Second, propagation rules for the worst-case uncertainty are provided in matrix and scalar form. It is highlighted that when WCU propagation cannot be computed, the Monte Carlo approach is the only way to obtain a correct expanded uncertainty assessment, in contrast to what can be inferred from the GUM. Third, examples of applications of the formulae to ordinary instruments and measurements are given. Also an example taken from the GUM is discussed, underlining some inconsistencies in it.

The aim of the paper is to introduce a parameter indicating a possible progressive deterioration of rotating machinery affected by any dynamic misalignment (due to increasing eccentricities, uneven mass distribution, propagating cracks, etc.). Such parameter, which has to be considered as a damage index, is based on a series of post-processing algorithms to be implemented on the vibration signals acquired on static supporting elements. The vibrations acquired from rotating machinery could be influenced by non-stationary and non-linear features, especially when the rotating elements are affected by dynamical unbalances due to misalignments or uneven mass distribution. The authors use the Hibert-Huang Transform tool, that is able to decompose the original signal into Intrinsic Mode Functions (IMFs), each of them holding quite significant information about the instantaneous frequencies and the energy content of the original signal.

Aim of the paper is to evaluate the reliability of a novel configuration of a Laser Doppler Vibrometer (LDV) for the measurement of vibrations affecting rotating components of machines. In the paper an analysis of errors due to the possible static misalignments of the mirrors utilized in an experimental apparatus has been carried out. This instrument was set up for the estimation of the out of plane vibrations of moving (rotating) objects, in order to give a better characterization of the self-tracking technique employed with the use of a 1D single point LDV and its measurements. The accuracies of the measures are mostly linked to the interaction between environment and instrumentation.

Hemodialysis treatment is biased by complications during its operative phases. One of these potential accidents consists in intradialytic hypotension, that causes discomfort to the patient and may even increase the risk of death. Therefore, it is very important to predict these events in routine clinical procedures. A cause of hypotension may be thermal energy/heat exchanges between extracorporeal system and the surrounding environment. A model to evaluate these heat losses is proposed and improved in order to maintain constant patient blood temperature. A convenient procedure is defined to improve and optimize clinical treatment. Although most hemodialysis machines automatically control the dialysate solution temperature starting from peripheral body temperature measurements, the proposed method is based on the control of the pre-dialysis core temperature of the patient, and the temperature of the blood entering the artery from the extracorporeal circuit after the treatment in the dialyzer. Measurements of arterial and venous blood temperatures are obtained in a non invasive way by a suitable estimate of the thermal energy exchanges between the blood and the environment during the extracorporeal recirculation. The suggested model guarantees a constant core temperature of the patient, improving prevention from intradialytic hypotension.

The present paper describes a procedure improving the measurement of fluid flow rates in pipes through the measurement of vibrations. The authors show, via experimental tests for water system, that for a given pipe in terms of width, diameter and material, the first harmonic amplitude of the vibration signal transmitted from the flow to the pipe walls is linearly proportional to the flow rate at a given revolution of the pump. Then, accelerometer mini/micro-transducers can be used for non-intrusive, low-cost and reliable flow rate measurements without load errors.

Wilson disease is a pathology because of a gene mutation causing malfunction in the copper excretion from the organism. Therefore, copper accumulation in the body gives rise to oxidative processes. Hence, this rare disease causes several disorders affecting tissues and organs. Neurological disorders lead to copper accumulation in the brain. Approximately 95% of individuals with neurological/psychiatric disorders show a visible symptom in their eyes known as Kayser-Fleischer ring. It is a golden-brown, sometimes orange or greyish, ring because of copper deposit in the cornea. In the medical screening, it is considered as a diagnostic sign of Wilson disease more than ever in individuals with neurological problems. The authors propose an innovative technique based on ocular biometric measurements to diagnose the pathology and the origin of a neurological disorder. An image processing algorithm detects the Kayser-Fleischer ring in the eye cornea through segmentation. Subsequently, biometric measurements provide further information on the severity level of pathology. The aim is to provide a non-invasive diagnostic technique to improve the accuracy of the current methods used in practice and to reduce the possible interpretation errors.
