使用槽道平均模型的多叶片排N-S方程并行计算

1前言多叶片排三元粘性计算，正在成为压气机、涡轮设计的重要工具。与混合平面模型山相比，槽道平均模型p］能够更加精确地模拟动静叶片间相互作用。它减少了内边界信息传递积累误差，增强了计算程序的鲁棒性。国内很多单位开展了有关的研究工作［‘－’］。本文发展了使用槽道平均模型多叶片N－S方程并行计算程序，并对一多级压气机设计中间方案的前3级进行了试算。2关于槽道周向平均模型这一模型是由Ad。mCZyk［’l提出，它不但被应用于三维直接计算数值模拟，其中的一些基本概念还曾被应用于两类流面迭代平均SZ流面计算。其主要思路…

MRALLEL NUMERICAL ANALYSIS FOR MULTISTAGE COMPRESSOR USING MERAGE PASSAGE MODEL

The use of Navier-Stokes simulation in the daily design process of multistage compressor requires extremely large computer resources. A less expensive alternate is the development of parallel numerical simulation on a workstations cluster for parallel distributed supercomputer. An average-passage model was introduced to include the unsteady flow effects and wake blockage and to make all of the flow variables are continues at the interface planes. A parallel Navier-Stokes solver has been developed for multistage high pressure ratio compressor based on domain decomposition methodology. This multiblade row solver was applied to analyze the flow field of the first 3 stage blade rows of a 7 stage high pressure ratio compressor at the design point.
