Hi My friends...
I simulate 2 phase flow(air and water) in the channel. I set velocity inlet and pressure outlet for boundary condition. Also no slip B.C for walls. My simulation is transient and laminar. My channel has grooves that filled with air for initial condition.( I attached file. Maybe it can explain it better for you.)
My problem is , my inlet pressure never become stable and all the time changed with iterations.
What's the problem???
Thank you
