Study on the radiation flux and temperature distributions of the concentrator–receiver system in a solar dish/Stirling power facility
TL;DR: In this paper, the Monte-Carlo ray-tracing method is utilized to predict the radiation flux distributions of the concentrator-receiver system, and the resulting radiation flux profiles are subsequently transferred to a CFD code as boundary conditions to numerically simulate the fluid flow and conjugate heat transfer in the receiver cavity by coupling the radiation, natural convection and heat conduction together.
