摘要： 基于作者本人发展的用于分析求解叶轮机械三元跨声速势流的AF2格式,并结合Jameson发展的用于求解二元跨声速势流的MAD格式,本文提出了一种用于快速求解叶轮机械三元跨声速势流的新的全隐式多重网格分解因式格式(MAF格式)并用其对西德DFVLR单级轴流式压气机转子三元跨声速流场进行了求解计算。

Abstract: Based on the AF2 scheme and the multiple grid scheme, a fast implicit multigrid approximate factorization scheme (MAF) for solving the three-dimensional conservative full potential equation has been developed and is presented in this paper. The new MAF scheme has been used to solve the three-dimensional transonic flow within DFVLR axial-flow single-stage compressor rotor, and the computed results have been compared with the DFVLR data and the results computed by AF2 scheme.
