In this research work, a three dimensional model of the solid solar particle receiver (SPR) with the influence of aerowindow is analyzed. The free-falling down particles will form a solid particle curtain and be directly heated up by the reflected concentrating solar energy which passes through the aperture of the cavity. The mass, momentum and energy exchange between the solid particle phase and gas fluid phase are simulated by the two-way coupling Euler-Lagrange method. A discrete ordinate radiative transfer method has been applied to study the coupling of radiative heat transfer and the falling particle curtain. The realizable κ-ε model is used in the investigation of turbulence flow. In order to predict the performance of the SPR, the aerodynamic behavior of the particles and thermal interaction, which include particle-particle radiation, particle-wall radiation, particle-air convection, and air-wall convection are analyzed and demonstrated in this work. All the investigation on the simulation model is focusing on optimizing the performance of the SPR. The parametric studies of the performance of the SPR with aerowindow are investigated under the different working conditions, such as air injection velocity, particle mass flow rate, and the efficiency of the SPR and exit average particle temperature are compared upon these conditions.
