The boundary condition for the countercurrent
Hi There are two kind fluids (liquid and gas) in my system and the system is the countercurrent. The gas phase inputs at the bottom boundary of the geometer and leaves at the top boundary. The liquid inputs at the top boundary and leaves at the bottom.
Question 1 If the top bounady is set the inlet, can i use UDF to interpret that the gas phase can pass through the top boundary ? What macros I need use ?
Question 2 If the bottom boundary is set the outlet, can i use UDF to restrict that the gas phase can't pass through the bottom boundary but the liquid can pass ? What macros I need use ?
were you able to set up the boundary conditions for your simulation? I am having the same problem as you.
I really appreciate your help.
If both of you resolved this problem please shere it with me. I have the same problem. Thanh you in advance.
