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ν-′∞进行了修正,建立了气动力关联性更好的参数ν-″∞。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ν-″∞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ν-″∞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ν-′∞更加有效。
In order to apply the theory of viscous interference more accurately to practical engineering, based on the theory of viscous interference hypersonic plate and the theory of oblique shock, aiming at the coherent disturbance correlation parameter ν-∞ currently widely used Correction and establish a better parameter of aerodynamic correlation ν- “∞. The CFD numerical method was used to simulate the viscous interference effect of the orbiter OV-102 under typical conditions. After the correction Viscous interference correlation parameter ν- ”∞ for the aerodynamic data correlation characteristics. The results of the verification show that the modified cohesion disturbance correlation parameter ν- "∞ has good correlation characteristics with viscous-induced aerodynamic data, and compared with the uncorrected viscosity disturbance correlation parameter ν-∞ effective.
