Calculation of hypersonic flow on the pointed bodies within framework of full viscous shock layer model

Existing hypersonic wind tunnels do not permit complete modeling of flight conditions at high Mach numbers (М>20). This has enhanced the importance of methods for numerically simulation of hypersonic flows. A good approximation for the flows at high Mach numbers (М>10) and moderate Reynolds numbers (Rex =10^4-10^5) is the full viscous shock layer (FVSL) model. The purpose of this work is the theoretical study of a hypersonic shock layer on sharp bodies (plate, cone) within the framework of FVSL-model and study of influence of various parameters on the characteristics of the shock layer. As a result of the analysis of this material the universal dimensionless dependencies of Stanton numbers (for flat and axisimmetric flows) from Reynolds number, Mach number, temperature factor, the cone half-angle and the angle of attack are received. It allows better to understand laws of this flows and promotes the decision of various applied tasks.
