bubble detachment in porous media
 

hi everyone
i have attempted to model bubble dynamics in a porous medium.
to validate my results i have compared my results with R.Ranjans results of the same topic.
i have done exactly everything he did but my temperature contours are different from his.i even used the same UDF as Ranjan. you can see Ranjans contous bellow.

in my case, the vapor temperature begins to rise as time is increased and it goes as high as the superheated liquid.but in ranjans contour vapor remains at the saturation temperature as it should in reality.does any body have any idea what i might have done wrong?
