This paper describes a two-dimensional computational fluid dynamics (CFD) model of flow with mass transfer to simulate a membrane separation system. The fluid domain comprises two reverse osmosis (RO) membranes and is fitted with different wavy…

The objective of this work is to carry out a sizing program of the photovoltaic system isolated from the grid by determining the size of the subsystems that make up the photovoltaic generator, the batteries, the charge regulator and the…

 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…

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…

A research on Thermo-hydraulic performance carried out on three types of heat exchanger with different baffles inclination 15°, 25°, 45° by the computer code Fluent, the model achievable is turbulence . The results show big recirculation zones and…

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…
