Abstract

This paper studies the effect of the combined natural convection and radiation on the heat transfer and this, in an inclined solar thermal collector. A 3D numerical code is developed to solve respectively the convection equations according to the vorticity-vector potential formulation and the radiation equation. The discretize schema is the control volume method for the convection and the FTnFVM for the radiative equation. Numerical solutions are obtained for Pr=0.71, Ra=105, and the radiation-conduction parameter (rc) ranging from 0 to ∞. The medium is considered as gray. Indeed, it emits and absorbs heat.
