Hello everyone!
I'm working on my project and I'm trying to simulate a 2-phase flow over a naca 4412 hydrofoil. I want to do simulations for 15 different cavitation numbers and i have some problems with the boundary conditions.
The cavitation number is given by: σ = (Pref - Psat) / (0,5*ρ*u^2)
all constant except Preference (which changes every time)
Psat = 1706 Pa
Ux=0,69 m/s
Uy=0,097 m/s
ρ=998,2
What boundary conditions should I try to get correct results?
I use structure mesh with 151000 cells, spallart almaras model and coupled solver
Any possible help from anyone is welcome!
Thanks in advance...
