摘要

为了更精确地将黏性干扰相关性理论应用到实际工程上,基于高超声速平板黏性干扰相关性理论和斜激波理论,针对当前广泛采用的黏性干扰相关性参数v'_∞进行了修正,建立了气动力关联性更好的参数v″_∞。采用计算流体力学(CFD)数值方法模拟了航天飞机轨道器外形OV-102在典型状态下的黏性干扰效应,考察了修正后黏性干扰相关性参数v″_∞对于气动力数据的关联特性。验证结果表明:修正后的黏性干扰相关性参数v″_∞对于黏性诱导的各气动力数据均有良好的关联特性,并且相比未修正的黏性干扰相关性参数v'_∞更加有效。

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'_∞.
