A Study of Flow Analysis for a Vertical Pump with Diffuser
디퓨저를 갖는 수직펌프의 유동해석에 대한 연구
Abstract
Flow analysis was carried out for two vertical pumps. The geometrical difference of two pumps is the adoption of vaned diffuser. Full pump models were used to simulate the velocity fields of the pumps. Pump head and velocity field were compared to obtain the features of diffuser flow. It was shown that the discontinuity of head curve was predicted and reverse flow could be generated at impeller exit even in the rated flow condition.
