Numerical Analysis of the Subsurface Vortices in the Pump Sump Models
- 발행 : 2005.12.01
초록
In order to study the characteristics of the subsurface vortex the flow fields of the three pump sump models were analysed by the numerical simulation. The calculation results show that there are circulation flows in the pump sump model and maximum vorticity strength which make iso-surface from the wall to the pump inlet could be used for predicting the subsurface vortex generation. Also, the flow field for the sump model with anti-vortex devices simulated and the results shows that there is no vorticity value which make iso-surface from the sump wall to the pump inlet.
