Abstract

In order to apply the viscous interaction correlation theory to engineering practice more precisely, the common viscous interaction correlation parameter v'_∞ is corrected and a more correlative parameter v″_∞ of aerodynamic forces is established based on the plane viscous interaction correlation theory and oblique shock wave theory at hypersonic velocity. The viscous interaction effect on OV-102 space shuttle under typical conditions is examined with numerical simulations by a computational fluid dynamics (CFD) method and the corrected viscous interaction correlation parameter v″_∞ is examined for its correlativity with the aerodynamic force coefficients. The results show that the corrected viscous interaction correlation parameter v″_∞ gives a good correlativity with all the aerodynamic force coefficients induced by viscosity and proves more effective than parameter v'_∞.
