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…

In order to study the transient thermal behaviour of a shell-and-tube latent thermal energy storage (LTES) unit using phase change material (PCM) under variable heat transfer fluid (HTF) inlet velocities, a mathematical model based on the enthalpy…

This work reports a detailed numerical study that is aimed to determine the variation of the three principal parameters, temperature of two phase change materials (PCMs), heat transfer rate and heat transfer fluid (HTF) outlet temperature, during…

Nous présentons une étude numérique et analytique concernant le transfert combiné de chaleur et de masse dans un milieux poreux. Ce milieu est globalement homogène et présente une anisotropie thermique. L'équation qui gouverne l’écoulement est celle…

The autonomous operation mode of paralleled inverters in microgrids can be intentional or unintentional in order to ensure the continuity of supply. In this mode the voltage and frequency magnitudes are held by local controllers using droop control,…

In Photovoltaic, many semiconductors materials are used. These materials possess different optical, electrical and mechanical properties. However, the present technologies used in the solar cell manufacture, depend essentially for the material and…

Compte tenu de l’épuisement des énergies utilisées actuellement, telles que les énergies fossiles, et du constat établi par les experts concernant les exigences écologiques, il est nécessaire de trouver des nouvelles sources d’énergies afin de…

In this work, we investigate the influence of temperature on the series and shunt resistances of polycrystalline silicon solar cells and then to determine the specific expressions of both parasitic resistances as function of temperature. We have…

In this work we used a typical single family house in Algeria as an example, the influence of building type on the energetic efficiency of an integrated solar combisystem (SCS) is determined by means of numerical simulation using TRNSYS software…

In this study, the hygroscopicity and thermodynamic properties of figs were studied to simulate their hygroscopic behavior during storage and drying. The experimental results were analyzed by the nine models of sorption isotherms. The Peleg model was…
