摘要
采用贴体坐标系网格生成和RANS方程,对于主附体干扰流场的角区湍流流场进行数值计算.对流项的计算采用三阶迎风差分格式,使用了两层湍流模型并直接计算了主附体壁上的压力分布.
Wing-body junction turbulence flo-w is simulated by using RANS equation and boundary fitted coordinate technique. Three order differential scheme is used in the computation of convection term and two layers turbulence model are employed in the calculation.
