Default non-granular diameter Eulerian model
Posts: n/a

I want to simulate evaporation of a liquid in a horizontal tube. Herefore I want to use the eulerian model. I have to define my phases: -primary phase: liquid -secundary phase: vapor But here comes the problem, I've to set a diameter of the bubble of my vapor phase. I want to know how the liquid evaporates, so it's stupid to set a diameter which I want to let fluent calculate. I understand that Fluent maybe needs an initial value, so I've tried with one, and I get evaporation, but my interphase liq-vap wasn't very clear.

Can someone tell me how I can solve this problem?

thanks Jan
