Default Condensation on a vertical wall
Posts: n/a
Hello everyone,

I am using FLUENT to simulate water and vapor two phase laminar flow condensation on a vertical wall. I use VOF multiphase model to do this job. I made UDF for phase change mass transfer and heat transfer. My problem is that when I set gravity is zero, the reasults are well, but When I set gravity 9.81m/s^2, I can not get the correct temperature profile. Also the pressure gradient is very high. What I want is laminar film profile. Is that possible?
