A Numerical Study on the Improvement of Performance for the 2 Vane Pump Impeller

Received 20 April, 2020 Revised 27 May, 2020 Accepted 30 June, 2020 Abstract >> This paper describes a numerical study on the improvement of performance of the 2 vane pump impellers. The design of these impellers was optimized using a commercial computation fluid dynamics code and design of experiments. Geometric design variables were defined by the impeller blade angle distribution. The objective functions were defined as the total head, total efficiency and solid material size of the impellers. The importance of the geometric design variables was analyzed using 2 factorial designs. The interaction between the total head, total efficiency and solid material size, according to the impeller blade angle distribution, is discussed by analyzing the 2 factorial design results.
