Setting up k-e turbulent wall function for two-phase flow

metro · August 21, 2010, 04:02

Hey All,

I would like to know how to properly set up the k-e wall function and solver for wavy stratified flow. I have a thin liquid film which is flowing along a channel at low velocity (4m/s) therefore low Re. A gas is flowing over the thin film at a relatively high velocity (40m/s), therefore high Re. How do I set the turbulent model correctly so that I can capture the turbulence at the interface correctly? I am currently using interFoam as the solver.

Thanks in advance

Well, not spot on, but there is some information regarding BCs on http://www.cfd-online.com/Wiki/Turbu...ary_conditions
