Special features of the computer simulations of radiation heat exchange of the spacecraft in specular-diffuse approximation

The special features of the computer simulations of the radiation heat exchange calculations of spacecraft with specular-diffuse approximation of the nature of the surfaces reflection according to the algorithms, which realize the direct calculation of the radiation exchange factors by the Monte Carlo method, and to the algorithm of the author, which realizes calculation through the determination of semi total absorbed radiation exchange factors are considered. Effects of geometric model surfaces approximation method and calculation algorithm on fluxes and temperature results are shown.
