Abstract
This work presents numerical results of the investigation of the thermal performance of a volumetric solar receiver. The Thermal Non-Equilibrium Model and Rosseland approximation are utilized. The numerical technique employed for discretizing the governing equations was the control volume method with a boundary-fitted non-orthogonal coordinate system. The SIMPLE algorithm was used to handle the pressure-velocity coupling. Effects of porosity (ϕ) and mean particle diameter (Dp) in the solid-fluid temperature distributions and pressure drop on absorber porous were investigated. These solutions can serve as a useful tool in the preliminary design of a volumetric solar receiver.
