cavitation fluent
Hi
:confused::confused: can you help me how i simulate flow with cavitation around hydrofoil (naca0015) in fluent. please |
hi
for cavitation simulation you should use this proccess: model/mullty phase/mixture/number of phase2 material/select primary & secondary phase define/phases/phase1/select primary phase define/phases/phase2/select secondary phase define/phases/interaction/mass/select cavitation/set vapor pressure |
hi
thanks but i have problem.when i simulate the cas in fluent.vf-phase is not changed. |
hi
check pressure perhaps presure is upper than cavitation pressure |
excuse me
u should set version of fluent ddp too! |
hi
i use fluent 6.3.26.i think the problem is in characteritic of fluid;fr exmp:surface tension coef and non condensable gaz fraction.becaus i put 3166 pas for 25°C at pressure of vaporization;can you give me the correct values please thanks |
no if your material is water set true pressure for water surface tension And vapor pressure use this links:

hi
yes i use ddp version for 2d th |
