Hello Guys,

I am trying to model droplet entrainment by gas from water film and the deposition of this droplets too.

My question is how to model the drag between water droplet and water film. I am applying the three- fluid model approach and using CFX. I found only stuff dealing with droplet interaction time and turbulent effects which are difficult to implement in to this commercial code.

Reentrainment (deposition) plays too a very important role: at this moment Entrainment is well solved but because my droplet s becoming bigger they move under the water film.

thx Rebecca
