Calculating Radiation Exchange Factors of Radiant Cryocooler by the Monte Carlo Method

摘要

A computer program, intended for engineering calculation of radiation exchange factors of radiant cryocooler in real enclosure with diffuse emission and specular reflection surfaces, is described, The method is a simple Monte Carlo application. and the flow chart of computer program is provided. The radiant exchange factors of a two-stage radiant cryocooler have been calculated. The results are discussed and compared with the data obtained by the ordinary specular image method. Comparison shows that the Monte Carlo method has equal or better effect in simple cases and strong potential in complex cases. So, it is very useful to the designers of radiant cryocoolers.
