실험계수를 이용한 원심펌프 설계기법의 개발

Abstract

This study is focused on the performance prediction and design of a centrifugal pump with optimum shape. Design and analysis of centrifugal pumps rely on experience of designer due to many fluid mechanical and geometrical variables. In this study, a design method was developed with experimental factors and analysed by comparison with 2nd-order vortex panel method. Impeller is the most important component affecting the performance of the centrifugal pump. The predicted total head for three cases, of which designs were determined by this method, agrees well with a particular commercial pump. This study shows that satisfactory performance of an optimal pump shape can be obtained through the automatic design routine.
