摘要

涡轮压气机的单级压比有明显的提高趋势，尤其是轴向压气机。采用基于风洞试验数据的Q-3-D计算机程序，对压力比为3,0的轴向级候选者的可能参数进行了研究。研究了两个主要设计参数对期望效率、外围叶片转速和流动结构的影响。在流量系数为0.35和气流偏转角为12度时，预期可接受的效率水平和进口马赫数。计算结果为油田类型和CFD程序的进一步分析和改进提供了候选阶段。

Mathematical Modelling and Analysis of an Axial Compressor Supersonic Stage Impeller

There is an evident trend to elevate pressure ratio of a single stage of a turbo compressors - axial compressors in particular. Q-3-D computer program based on wind tunnel test data was applied to research possible parameters of axial stage candidates with pressure ratio 3,0. Influence of two main design parameters on expected efficiency, periphery blade speed and flow structure was studied. Acceptable level of efficiency and inlet Mach number are expected at flow rate coefficient = 0.35 and flow deflection angle = 12 degrees. The calculation results have led to a stage candidate for further analysis and improvement by field type and CFD programs.
