Abstract

In order to calculate the radiative heat transfer coefficient between the diffuse surface of the 3D gray body, this paper set up a cell cube model to represent the gray surface, and generated rays emitted from one surface(i. e. emission surface) by using Monte Carlo method. It was tracing the multiple reflections for each ray until the ray was totally absorbed. It recorded the absorbed energy at each ray-facet intersection to calculate the heat transfer coefficient between the emission surface and any other surface. To solve the over-consumption issue of radiative heat transfer coefficient based on Monte Carlo method between the diffuse surface of the 3D gray body, this paper used a Monte Carlo method based on GPU to realize the parallel computation, and used the unified programming architecture CUDA to get the realization of programming the Monte Carlo method. According to the CUDA random number generation algorithm, it parallelly computed the tracing process of the radiative transfer coefficient, and realized a parallel scheme for calculating the radiative transfer coefficient. Experimental results show that, compared with the CPU serial calculation method, the parallel Monte Carlo method based on CUDA architecture can obtain the calculated acceleration ratio of 80 times as high as the radiative heat transfer coefficient.
