Open publisher page 0 citations

Abstract

A centrifugal compressor with different convergence angle diffuser was simulated,the influence of convergence angle on compressor performance was analyzed in detail and finally the corresponding flow mechanism of influencing factors was acquired by combining the flow analysis,which brought the reference for designing centrifugal compressor vaneless diffuser and improving compressor performance.
