Design of Impeller and Diffuser for Mixed Flow Pump with Inverse Design Method
역설계 방법을 적용한 사류펌프의 임펠러 및 디퓨저 설계
- Published : 2009.06.25
Abstract
The impeller and vane diffuser for the mixed flow pump(NS550) was designed by using meridional selection program and inverse design method. We decided the meridional shape of the impeller from the meridional design parameter, such as the specific speed and maximum diameter at the impeller exit. The meridional shape of vane diffuser was set from the impeller shape, distribution of cross sectional area and maximum diffuser diameter. The angle of impeller blade and diffuser vane was designed by using inverse design method. The predicted overall performance by using commercial CFD code(ANSYS CFX-11) shown good agreement with design goals.
