Analysis of the Effect of Incrustation on Centrifugal Compressor Performance
摘要
Abstract
The performance of centrifugal compressor before and after being polluted is numerically calculated by floating field simulation software. The mechanism of compressor performance deterioration caused by incrustation was analyzed by comparing the chance of compressor flow field. The result was that the main effects of incrusta-tion on centrifugal compressor was to reduce compressor efficiency, because incrustation changed the blade sur-face roughness, increased friction loss, expanded the low speed range near the trailing edge and outlet, en-hanced the backflow, and increased the flow loss.关键词
