Interphase mass transfer in Eulerian-Lagrangian

Sameer

Hi all

I want to simulate mass transfer from single rising bubble to surrounding bulk fluid. In my problem, a bubble which is mixture of two components, of which one is soluble with bulk fluid surrounding the bubble. Here bulk fluid is pure liquid and operation is isothermal.

I tried to use Eulerian-Lagrangian multiphase model with 'variable composition mixtures' for both bulk fluid and bubble. My problem is that, in physics( under fluid- pairs it doesn't show any option for mass transfer model.

Where I made mistake in problem set-up? Or is interphase mass transfer not possible in Eulerian-Lagrangian multiphase model ?

Thanks.
