Numerical Simulation of a Heat Flux Around a Ballistic Model Using a Hyperbolic Quasi-Gas Dynamic System of Equations

Numerical simulation of a supersonic flow of a viscous heat-conducting gas around the HB-2 model for various angles of attack, α = 0°, 8°, and 16°, and temperatures of the model surface is carried out based on a compact hyperbolic system of quasi-gas dynamic (CHQGD) equations. The three-dimensional...

Description
Summary:Numerical simulation of a supersonic flow of a viscous heat-conducting gas around the HB-2 model for various angles of attack, α = 0°, 8°, and 16°, and temperatures of the model surface is carried out based on a compact hyperbolic system of quasi-gas dynamic (CHQGD) equations. The three-dimensional features of the flow and dependence of the heat flux on the angle of attack and wall temperature are investigated. The presence of the angle of attack leads to the formation of two longitudinal vortices on the leeward side of the model near the symmetry plane. These separation regions significantly affect the distribution of the heat flux on the leeward surface.
