Special Features of the Computer Simulation of the Radiation Heat Exchange of a Spacecraft in a Specular-Diffuse Approximation

Abstract

The special features of the computer simulations of the radiation heat exchange calculations of spacecraft (SC) with a specular-diffuse approximation of the nature of the surface reflection according to the algorithms, which directly calculate the radiation exchange factors by the Monte Carlo (MC) method, and according to the author’s algorithm, which calculate them by determining the specular exchange factors of the absorbed radiation, are considered. The effects of approximating the model’s geometric surface approximation method and calculation algorithm on the results of calculating the fluxes and temperature are shown.
