Dears Members,
Anyone has some experience for writing an UDF to introduce the drag force in a multiphase flow modeled by VOF model enable? More specified, I simulate the CO2 bubble absorbed in methanol liquid, the CO2 is inlet to the reactor from a hole on the bottom. my governing equations are continuity and momentum equations for he incompressible two-phase flow as follows:    and now I want to add the drag force source term to the momentum equation with UDF code. is there anyone can help me? this problem has been bothering me for a long time Last edited by piaoyangdexue; November 29, 2017 at 22:32. Reason: add several equition pictures to clear my ask for. |
