The output characteristics of photovoltaic systems are nonlinear and change with variations of temperature and irradiation, so we need a controller named maximum power point tracker MPPT to extract the maximum power at the terminal of photovoltaic…

This paper present novel approach for traction control of four wheel electric propulsion system for each wheel. This algorithm is necessary to improve the vehicle safety, the independent Machine Control philosophy is employed using an intelligent…

 A new type of non-polynomial fractional spline function for approximating solutions of Fredholm-integral equations has been presented. For this purpose, we used a new idea of fractional continuity conditions by using the Caputo fractional derivative…

Les méthodes analytiques permettant l’obtention des équations qui décrivent les teneurs en eau des produits agro-alimentaires sont jusqu’à présent inexistantes; c’est pourquoi, les équations empiriques ont trouvé une large application. Cependant,…

L’objet de ce papier est de présenter le concept et la théorie d’une nouvelle approche de commande non linéaire pour un convertisseur cc/cc dévolteur (Buk Converter) connecté à une charge. Les résultats des études de simulation et de…

The article presents a numerical simulation on air flow and heat transfer characteristics in solar air collectors mounted with obstacles. Computational Fluid Dynamics, ‘CFD’ based on the finite volume method, SIMPLE algorithm and the turbulence…

This study presents a mathematical model based on the enthalpy method for the transient thermal behavior of a shell-and-tube latent thermal energy storage (LTES) unit using two kinds of phase change materials (PCMs) named PCM1 and PCM2, with…

The paper presents a numerical study of a compressible and turbulent coaxial jet, using a Large Eddy Simulation type approach. This study focuses on the implementation of a high-performance and modern numerical method to meet the requirements in…

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…

In this paper a theoretical model of the heat and mass processes in a tubular adsorber of a solid adsorption solar refrigerator is established. The modelling and the analysis of the adsorber is the key of such studies because of the complex coupled…
