Pump as Turbine- An Experience with CFX 5.6

The paper describes the investigation of Pump as Turbine using numerical approach. The case study describes various problems faced during modeling and the approaches used to resolve the problems. The unstructured mesh concept in CFX 5.6 resolved the complex blocking approach used in structured mesh. The geometries were modeled using Pro-E solid modeler and transferred to CFX. The results from the analysis were encouraging. The predicted performance showed a good trend with the experimental test results
