Study on the Leakage Flow and the Flow Analysis of Regenerative Pump
재생펌프의 누설 유동 및 내부 유동에 관한 연구
- Published : 2002.08.01
Abstract
Flows in a regenerative pump were calculated for several flow-rates, using the CFX-Tascflow. The calculated results show the vortex structure in the impeller and side channel. The predicted performance shows considerable discrepancy form the measured values for low flow rates. Main source of the difference is the leakage flow of pump strongly affecting the performance of pump. A simple correlation was proposed using calculated leakage flows through the parametric calculations of the simplified passage.
