摘要
采用数值模拟的手段 ,对压力恢复系统超声速扩散段三维流场进行研究。数值模拟使用 L U分解法和 NND差分格式求解全 Navier- Stokes方程 ,并加入了湍流模型。对得到的流场结构进行了分析 。
This report presented the time-depended fully implicit LU algorithm, which was used to solve the Navier-Stokes equations with NND difference scheme in numerical simulation to the flow field of supersonic diffuser in the pressure recovery system. The algebraic turbulence model as used to simulate the complicated flowfiled, and the computational result was analyzed for more advanced work.
