Default boundary condition
Posts: n/a
I need your help! my tank is a bubble column,three phase in it.Air bubbles come from the bottom of the column and flow out from the face of the water. How to set the boundary conditions? Especially how to set the outflow boundary? I try to use the pressure-outflow condition,but the result is not compellent. I think perhapse because only air flow out of the system,the water and the granule are still in the tank. I need your help!
