Threedimensional gas flow past blunt bodies in the framework of the parabolic viscous shock layer theory

The new asymptotical mathematical model of hypersonic viscous gas flow past blunt bodies with permeable surface is suggested and named the parabolic viscous shock layer theory (PVSL). This model is intermediate between thin (hypersonic) viscous shock layer model (TVSL) and full viscous shock layer theory (VSL). The solutions of the two- and threedimensional PVSL equations for wide range of body form are presented. The comparisons solutions of the PVSL equations with theoretical and experimental data of another papers are analysed and accuracy of suggested theory is estimated.
