RÉSUMÉ

With the aim of cooling the PV cells and recovering maximum heat dissipated by joule effect on the solar sensor, and thus to contribute to the improvement of the effectiveness of such a system, we are interested in the present study in the nonequilibrium thermal transfer of heat occurring between the coolant fluid and the exchanger (channel) partially filled by successive porous matrices. The coolant fluid saturating the porous medium is injected at different values of velocity and temperature. The model of the local thermal nonequilibrium (LTNE) is used to analyze the effects of some characteristic parameters such as the ratio of fluid and solid heat transfer coefficient Rs and the thermal conductivity ratio Rλ on the stability and flow mode and on the output of such exchange. Compromise values of these coefficients Rs and Rλ are necessary for obtaining a high-temperature outlet of the channel.
