Simulation the Effects of Solar Radiation in the Cavity Receiver by Using ANSYS for the Application in The Solar Power Generator

Abstract

This paper aims to investigate the effects the solar radiation on the cavity receiver for the Application in the Solar Power Generator (SPG). In order to perform work the solar power generator, high concentrated solar radiations are needed. thus, investigation of heat transfer of the cavity receiver is needed to conduct max usage of solar energy with min losing of heat for performance for the Solar Power Generator (SPG), in this research, Ansys software has been conducted to perform simulation process by using experimental results as a primary data for validation purpose. The experiments were conducted to find out the suitable aperture ration (AR = d/D) and aperture position (AP = H/D) of the cavity receiver (AR = 0.5 AP = 0.53). The results that done by simulation were confident 91% with the experiments results. The simulation process is conducted for solar radiation along the wall surface (H) of the receiver for different boundary conditions of the cavity receiver.
