How can define interface between solid and Fluid?
 

Hi,

I have a problem in which a heater is on leading edge of an airfoil and this airfoil is placed in Icing wind tunnel. Air is inside the tunnel at -5C. And water spray by using atomizer is also there.

I have to figure out how many water droplet impact on edge.

Could you tell me which model should i use? :confused:

Currently i am using (Eulerian+Discrete phase model).
I don't have any clue please guide me.

Secondly, how can i define interface between Heater and Fluid(Airfoil wall)?

It is very urgent.

Many Many thanks in advance.:)
