| Abstract: | In this paper,set the data of a NASA unshrouded impeller obtained by numerical test as an example,four kinds of impellers,which include the unshrouded impeller without tip clearance,unshrouded impeller with tip clearance,shrouded impeller and shrouded impeller with slots in blades,are analyzed and compared about flow field in detail. Furthermore,the analysis and comparison with the test results of unshrouded impeller are carried out,which shows the computational results are reliable. |
