Numerical Simulation Of Forced Convection In Receiver Of Two Concentrators: Dish Parabolic And Trough Parabolic

Résumé: Solar concentrators use reflective mirrors parabolics or parabolic cylindrical to concentrate the solar rays respectively in a point or linear focus. In the point focus or along the linear focus are the receptors (absorbers) which capture the solar heat thus concentrated. The objective of our work is to study numerically the convective heat transfer in a receiver of a dish and trough parabolics in order to choose the best one for the cooling application of a photovoltaic module. The permanent forms of the Navier-Stokes equations, the continuity and energy equations are solved by the finite element method. The results obtained are presented in the form of average Nusselt number and receiver temperature will be presented for various combinations of Reynolds number. The results obtained show that the dish parabolic is better for our cooling application.
