Hi,

I am using chtMultiRegionTwoPhaseEulerFoam to simulate problem for flow through a channel with side walls having thickness, which takes into account of conjugate heat transfer. In this case, liquid enters with phase fraction 1 and gas with 0 phase fraction and upon the course of simulation liquid must vaporize from the two sides, physically.

However, this doesn't happen actually. It seems to be note that flow field is looking okay but not the distribution of phase fraction.

I have attached three screenshots: the first one (temperature field of both fluid and solid), second one (gas phase fraction with solid temperature), and third one (fluid velocity with solid temperature).

Please suggest me some modeling aspects for chtMultiRegionTwoPhaseEulerFoam so that I can rectify it.


Otherthing, that I am worried about the usage of iDmdt in relaxationFactor sub-dictionary.


Regards,
Govind
