Abstract |
Experimental determination of aerodynamic data for high altitudes is difficult not only with technical, but also from an economic point of view. Therefore, the main tools for the study of aerodynamic characteristics of re-entry vehicles are numerical methods of rarefied gas dynamics. The development of numerical methods in rarefied gas dynamics is primarily due to the use of direct simulation method (Monte Carlo). In this paper present algorithm of the Monte Carlo method and the various gas-surface interaction models. The results of the aerodynamic characteristics of re-entry vehicles obtained by Monte Carlo method at different gas-surface interaction models are described. Keywords— Monte-Carlo method, rarefied gas dynamics, gas-surface interaction models, Maxwell model, Cercignani- Lampis-Lord model, space vehicle, high-altitude aerodynamics. | |||||||||
