Benefits of CFD Approach
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.
