本文介绍了低反力度吸附式压气机的应用背景,并基于两种低反力度压气机设计理念初步设计了一台三级高负荷吸附式压气机。三维数值模拟结果显示,在叶尖切线速度为370m/s,整机通流效率不低于86%的条件下,多级吸附式压气机实现了6的总压比,进一步验证了低反力度设计理念在高负荷压气机设计中应用的可行性。通过详细分析设计点处一维、S2气动参数分布以及三维流场细节并兼顾抽吸方案的复杂程度,对初步设计方案进行总结分析,为进一步优化设计工作提供了参考依据。
This paper introduces the application background of low reverse-pressure adsorption compressor and preliminarily designs a three-stage high-load adsorption compressor based on the design concept of two low reverse-pressure compressor. The results of three-dimensional numerical simulation show that the multistage adsorption compressor achieves a total pressure ratio of 6 under the conditions of a blade tip tangential speed of 370m / s and an overall throughflow efficiency of not less than 86%, further verifying that the low reverse force Feasibility of Application of Design Concept in High Load Compressor Design. Through detailed analysis of one-dimensional, S2 aerodynamic parameter distribution and three-dimensional flow field details at the design point and taking into account the complexity of the suction scheme, the preliminary design scheme is summarized and analyzed, which provides a reference for further optimization of the design work.
