Hello, I use bubbleFoam solver, and I’d like to simulate a rectangular bubble column(100cm×20cm×5cm) . And the detail is below.
The mesh consists of 33,000 cells in total.(h=125cells,w=33cells,d=8cells) The bubble inlet is centered with an area of 5cm×2cm by createPatch. And this simulation runs the initial filling level is height of 50cm by setField.
The B.C. of Ua at inlet is fixedValue uniform(0 0.01 0),and that of alpha is fixedValue uniform 0.01,and that of Ub is fixedValue uniform(0 0 0).
The B.C. of outlet is inletOutlet as same as tutorial case.
I simulated with above conditions. So the air-liquid surface gets higher and higher each time. And this doesn’t occur in the case that the bubble inlet is the same of bottom patch.
I think the surface gets higher at first and after that it should become constant level.
Please give me some opinion or advice.
