Lift force coefficient for 2-phase flow -- CFD Online Discussion Forums

April 29, 2008, 17:58	Lift force coefficient for 2-phase flow	#1
Summer Guest Posts: n/a	Hello, I am using Eulerian multiphase model to simulate air-water two-phase flow. I would like to define the lift force coefficient using UDF. Since the lift force on the air is equal to the negative value of lift force on the liquid, I want to know which lift force coefficient I should define in my UDF, the one on the primary phase (air) or the secondary phase (liquid). Any suggestion is valuable and welcome. Thank you very much!
