Abstract
The results of mathematically modeling axisymmetric hypersonic flow past an ellipsoid are presented. The calculation data are obtained on the basis of a numerical solution of the complete Navier—Stokes equations using a finite-difference method. The investigation is carried out for the problem of laminar flow over the windward side of the body. The effect of the elongation of the ellipsoid on the total heat flux and the viscous and pressure drag is considered. Results are obtained for three different gas (air) models: the perfect gas, chemical equilibrium and chemical nonequilibrium models. For the latter model various sets of catalyticity coefficients are considered. The effect of the real properties of air on the integral aerodynamic characteristics of ellipsoids with different elongations is analyzed.
