Performance Variations of a Small Centrifugal Compressor with Exit Blade Thickness

초소형 원심압축기의 날개 두께 변화에 따른 성능에 관한 실험적 연구

Some sized centrifugal compressors were designed and their performance measured to investigate the effects of exit blade thickness, width and back swept angle. The impeller of larger blade thickness shows low pressure ratio compared with that of smaller ones. Backswept angle also have a large effect on the efficiency. Measured values of slip factor are quite different from the estimated values of the Wiesner-Busemann model and an increase in the flow late.
