Steam condensation

I have saturated steam in a rotating cylinder. The steam gives away heat to the surroundings and gets converted into water which because of gravity comes down and depending on the speed forms a rim on the inner surface of the cylinder.
I want to simulate this and make an animation. I got some evaporation tutorial and looking at that I started to model condensation model. I have used mixture model, I gave standard state enthalpy values of water and vapor such that their difference is latent heat. I gave mass transfer mechanism as condensation-evaporation model where I have given the saturated temperature value of the steam. But I don't see any water falling down and getting collected at the bottom. Somebody can share their thoughts or any tutorials on this . Thanks ! |

By default the condensation frequency is 0.1, if you expect that condensation will occur at an accelerated rate, you ought to enter a high value for this. much like the weight factor for condensation. let me know how it goes.
