摘要 本文采用LU-SGS-GE隐式格式和改良型高精度、高分辨率的 MUSCLTVD格式求解平均的 Navier-Stokes方程和低Reynolds数q-ω双方程湍流模型。利用分区处理及分布式网络并行计算技术,在多台个人计算机上完成了叶轮机械内部三维粘性流场的快速并行求解。仅将计算域拆分成8份,并行加速比就可达7.4。 This paper solves the compressible, three-dimensional Navier-Stokes equations and the low-Reynolds-number two- equation q梬 turbulence model using LU-SGS-GE implicit scheme and modified Higher-order, high resolution MUSCL TVD scheme for numerical simulation of three-dimensional viscid flow field within turbomachinery. And this process is accelerated by utilizing multidomain treatment and distributed parallel computation. Computation speed under 8 domains is 7.4 times faster than single domain.
