| CFD approach leads to better hydraulics performance ( i.e. Efficiency / Cavitation / Hyd. Loss characteristic ) and enables optimum study. | |
| Existing model can be analysed and design guide lines can be drawn for future cases. | |
| In a long term this will enable us to reduced number of model test and optimization of “Jyoti’s” designs. |
