Computational Investigation of Infrared Radiation Characteristic of Surface Base on MT and RMC

Abstract:

A fast and accurate infrared radiation calculation method was investigated. Reverse Monte Carlo (RMC) method was adopted to calculate the Infrared (IR) Radiation characteristic of surface. The computational code used Mersenne Twister (MT) method to generate random number, and bounding box method to accelerate computational speed. The Infrared Radiation characteristics of some typical geometric structures were calculated and verified. The effects of emission photons number and mesh number on calculation results were analyzed. The results show the error between calculation value and theoretical value is less than 0.02%. The calculation time is proportional to emission photons number and mesh number.
