Evaporating Drop Model

Hi All,

I am trying to model a liquid drop on the end of a pipe. The pipe feeds into the drop, while evaporation takes mass away. I've build a 2D axisymmetric model of my pipe and drop, but I would like the size of my drop vary as it should be coupled to the temperature of the fluid. What is the best way to go about this? Can I set the radius of my drop to be temperature dependent when building my model?

Thanks!

If the size of drop doesn't change significantly, use "Laminar Two-Phase Flow, Moving Mesh" coupled with "Heat transfer in fluids". This way you can impose a mass flux to the liquid-vapor interface. The volume of the drop shrinks according to the evaporation flux.
