dh/dt=d/dx(alpha*dh/dx)-rho*latentheat*d(liquidfraction)/dt.
I took
partial differentiation operator : pd(fl(T),t)
into the source term "rho*latentheat*d(liquidfraction)/dt"
But I couldn't find any difference with source term=0.
fl(T) was T dependent variable : '1*(T>Tref)'
plz help ~
thank you

Did you solve your problem with the phase change?
I have a big trouble with this.....in a concentric tube heat exchanger where steam becomes liquid and i don´t know how to model this situation. help me plz
Thanks
