modeling sessile droplet evaporation

Dear Firends,

does any one has experience with modeling phase change from liquid to gas ? is there exists any tutorial ?

I intended to model evaporation of single droplet pinned of relatively hot serface .

I used general heat trasfer , incompresible navier stock and 2phase flow laminar phase field .


how could I check the conservation of mass and energy ?

I tried to run above problem with Moving Mesh ,ALE but I could not ,any suggestion ?

there is one toturial regarding 'Boiling water' I can not implement q (heat flux 1 & 2 ) in expresion ! I got error in expression and I can not run it , I assume t must be defined in other way but I have no idea how it should be define !

thank you in advance for your time and consideration

Hi Maryam,

It seems that you want to do the same thing that these guys did before:

I think that you can contact them directly and ask your questions.

I am also trying to model surface evaporation but it is difficult and there is no similar model unfortunately.


Cheers,
SMHH
