How to set cavitation number for cavitating foil

May 18, 2007, 01:11

I would like to set cavitation number (sigma= 0.8 & 0.4) to analyze caviating foil.Can you please tell me how I can set the cavitation number in FLUENT.

Thanks,

MMK

Hi!

You just have to define the apropriate pressure at outlet (at pressure outlet bc). You have to be careful where you define the desired cavitation number. For example if you want it to be 0.8 at inlet and you define it at outlet you have to take the losses into account (it's an iterative procedure). You can send me an email and I'll send you some papers...
