A dynamic mathematical model used to predict the performance of passive cooling system by evapo-reflective roof in buildings for hot arid climates has been developed. The cooling system consists of a roof composed of concrete ceiling and flat…

La présente étude s’intéresse à la fois au développement de la couche limite turbulente en écoulement supersonique sur une plaque plane, à la distance requise pour qu’elle envahisse toute la section de la plaque, ainsi qu’aux effets de la taille de…

The flow in an Over-Expanded Nozzle is subjected to shock waves leading to the unsteady separation of the boundary layer. Free detachment may be followed by a restricted detachment. During the expansion regime in propellant nozzles, several physical…

Applications of Heliostats for solar power tower plants increased in the recent years. Most of the solar power tower plants installed are on flat terrain and they may be subjected to wind loads. In the present study, a refined method for calculating…

L’Algérie occupe une surface de 2 381 741 km2, cela lui donne l’avantage de posséder les diverses sources d’énergie renouvelables comme l’énergie éolienne et l’énergie solaire. Cette dernière commence à avoir la lumière, l’état algérien a lancé un…

One of the most delicate parts to size in a water pumping windmill is the pump rod. Indeed, frequent ruptures during the exploitation and experimentation of windmills shows that the determination of the real forces acting on the pump rod is quite…

In this study, we present a new control method entitled direct power control without voltage sensors of a grid connected photovoltaic system associated with an active power filter. The direct control of power (DPC) is employed for the calculation of…

The concept of convexity and its various generalizations is important for quantitative and qualitative studies in operations research or applied mathematics. Recently, E-convex sets and functions were introduced with important implications across…

Estimation of solar irradiance received on the ground is essential in many solar energy applications, particularly those relying on concentrating solar technologies. In this work, we propose a model to estimate the spatial distribution of global…

In this study, many experiments were carried out to assess the influence of the some input parameters on performance of the multilayer perceptron techniques, which is architectures one of the artificial neural network (ANN). To estimate the daily…
