CFD에 의한 원심펌프 성능해석에 관한 연구

A Study on the Performance Analysis of a Centrifugal Pump by CFD

A commercial CFD code is applied to analyze the 3-D viscous flow field within the impeller of centrifugal pump. Design conditions are based on 75% of design efficiency. Two design conditions (Case1, Case2) with the different blade number and blade outlet breadth are performed by changing flow rate from 8 to 26 ㎥/h at the constant 3500 rpm. The characteristics of Case1 and Case2 such as total pressure coefficient, total head, shaft horse power, power efficiency are represented due to flow rate changing at the 50% position of span direction.
