Numerical analysis of flow characteristic in double suction pump
- 발행 : 1999.12.01
초록
The flow characteristics of double suction pump are investigated by numerically Calculations are performed by using SIMPLE algorithm at the design and off-design points. Symmetric nature of flow fields in blade channels is discovered at design point, but asymmetirc effects are discovered at the off-design point. Numerical results show that the formation of secondary flow in volute of double suction pump shows different trends when compared with the case of single suction pump. Also results show that double vortices are formed in the volute cross section.
