압력보정법을 이용한 8개의 원심압축기 임펠러 CFD의 적용 연구
Application of Pressure Correction Method to CFD Work for 8 Centrifugal Compressor Impellers
- 발행 : 2000.12.01
초록
Two representative finite volume methods, i.e., the time marching method and the pressure correction method, were applied to 8 centrifugal compressor impeller flows, with low to very high level of pressure ratio, among which 7 impellers' experimental performance is given in the open literature. The present study is focused on the prediction differences from both methods, developed by the authors, in the pressure correction method's point of view. In all cases, the time marching method gives a satifactory solution, but the pressure correction method does not. Up to about
