Abstract
In order to realize the fast performance analysis of centrifugal compressor, the performance calculation program of centrifugal compressor based on time marching throughflow method was developed. On this basis, combined with blade parameterization method and multi-objective genetic algorithm, the aerodynamic performance of LSCC and Krain centrifugal compressor was optimized with efficiency and pressure ratio as optimization objectives on design point. The results show that, compared with the prototype, the efficiency of LSCC compressor at design point was increased by 0.28\(\%\), the total pressure ratio was improved by 0.551\(\%\), and its stable working range was widened furtherly; the efficiency of Krain compressor at design point was increased by 0.518\(\%\); the total pressure ratio was improved by 2.27\(\%\); at the same time, the effectiveness of the performance optimization method was verified.
