Two-Phase flow in COMSOL

I am solving two-phase system (liquid-gas) and would like to use 2-fluid approach. Whether it is possible to use the built in equations for mass, momentum, energy etc. and add a multiplier such as phi_l and phi_g to account for two-phases. Is there any way to model two-phase flow using two-fluid approach in COMSOL?

Any comments will be highly appreciated.
Regards
Naveed

Hi, you would be interested in the Level Set application mode in the Chemical Engineering Module. Here is and example:

Hi Niklas

Thanks! In my opinion, the level set/phase field approach is limited to two immiscible fluids and computes one velocity field. I am not sure if there is any way to model using two phases as two separate fluids and thus computing each phase velocity field. Also, not sure if the built in multi-phase module can do mist flow modelling?
