Heat flux boundary condition in mixture model for multiphase flow
 

Hii ...... I am modelling multi phase flow of air and water in fluent using the mixture model as my proposed flow regimes include bubbly, slug and annular flows. I am able to get answer if I do not apply heat flux boundary condition. But in my problem specification I require a heat flux of around 500 W/m2. When I do so through the boundary condition dialog box, I am not able to get correct answer. Please help me in this regard.
