摘要
采用高斯型滤波函数对Navier Stokes方程进行滤波处理 ,并引入亚格子雷诺应力模型推导出了在水力机械内部流场计算中实用的二维大涡模拟方程及其在物理平面和计算平面上的离散形式 。
The Gauss filter function is used to filter the Navier stokes equation and the subgrid scale Reynold stresses model is introduced to deduce the practical form of LES equation for two dimensional case and its discrete form on physical plane and computational plane for flow field calculation of hydraulic machine. The numerical solution of the equations is introduced, also.
