Analysis of impeller exit condition using a modified Stanitz equation in a centrifugal refrigerant compressor

예측수정된 Stanitz 방정식을 이용한 임펠러 출구 조건 해석

We have measured pressure distributions within the diffuser and pressures at the inlet and outlet of the compressor in orde to match impeller and low-solidity diffuser of 500RT centrifugal refrigerant-compressor which has been developed in LG Cable Ltd. Modified Stanitz equation is used to predict the measured data by tuning several parameters and then is validated. Using the validated parameters and modified Stanitz equation, we have obtained data necessary to design the diffuser.
