- Аннотация: The paper is devoted to the comparative study of Shakhov model kinetic equation andDirect Simulation Monte Carlo (DSMC) solutions as applied to high-speed flow of amonatomic gas over generic three-dimensional space vehicle under angle of attack.The corresponding calculations are carried out using Nesvetay and SMILE softwarepackages, developed by the authors. Satisfactory agreement is shown for surfacedistribution of pressure, friction and heat transfer coefficients despite very differentmodeling approaches and computational meshes employed. It is thus shown that the useof the model kinetic equations with approximate collision integrals provides accurateresults for high-speed external monatomic gas flows over complex three-dimensionalgeometries at acceptable computational cost.
