摘要

基于燃料电池空压机试验平台测试两级空压机气动性能

并以此验证仿真模型的准确性。为提高两级空压机气动性能

利用仿真模型结合㶲分析方法研究两级空压机各部件㶲损分布及大小。结果表明：高压级㶲损比低压级高58.06 J

而高压级叶轮㶲损占整个高压级㶲损的54%。通过对叶轮㶲损因素分析发现湍流引起的不可逆损失是导致其㶲损最主要原因。

Abstract

To improve the aerodynamic performance of two-stage air compressors

a CFD model was developed and then verified via the experiments carried out on a fuel cell air compressor test bench. Based on this model

the distribution and magnitude of exergy loss for each componentwere derived. The results indicates that the exergy loss at the high-pressure end is 58.06 J higher than the low-pressure end. The exergy loss of impeller accounts for 54% of the total exergy loss at the high-pressure end. The loss factor analysis reveals that irreversible loss due to turbulence is the primary contribution.
