ウェットガス条件における遠心圧縮機の性能計測

抄録

In this study, we developed the new centrifugal compressor test facility which could make the wet gas conditions (LMF is up to 15%) and analyzed the influence of the mist flow on the fluid performance of the centrifugal compressor. As a result, we confirmed the adiabatic efficiency decreased with increasing in LMF. The main cause was increase in the shaft power. Moreover, we assumed that the liquid film on the inner wall of the impeller was discharged from the trailing edge at a circumferential speed by the centrifugal force. Then we confirmed that an accuracy of the predicted shaft power increase at the maximum LMF of 15% based on the assumption was 3.7%
