Numerical simulations of Shock- wave turbulent boundary- layer interaction on Delery's bump using GAO- YONC compressible turbulence equations are presented. Properties of turbulent flow,such as multiscale,nonequilibnum and anisotropy in GAO- YONG turbulent equations have been analyzed. Convection terms and diffusion terms are calculated using ROE (flux difference splitting) scheme and CD (center difference) scheme respectively. The Runge- Kutta time marching method is employed to solve space discrete control equations. Typical flow features are described well in simulation,such as pressure platform in separation zone, A flow structure. Meanwhile, calculations accurately predict distribution of pressure on the bump wall ,mean velocity profiles and turbulent shear stress. Good agreements between the calculations and experiment are obtained.%用GAO-YONG可压缩湍流方程数值模拟了Delery管道凸起跨音流场中的激波湍流边界层干扰现象,分析了GAO-YONG可压缩湍流方程组对湍流的非平衡、多尺度、各向异性等特性的描述能力.计算中对流项、扩散项分别采用二阶ROE格式和二阶中心差分格式离散,并用多步Runge-Kutta显式时间推进法求解了空间离散后的控制方程.计算很好地模拟到了压力平台区、“λ”波结构等典型激波湍流边界层干扰的流动现象,也得到了壁面压力分布、平均速度剖面以及雷诺压力分布等,并与相应的实验数据进行了对比分析,两者符合很好.
