Hi,I have a problem about the heat transfer of two immiscible fluid. In brief, the cold n-butane drop rises freely in a column of warm water.The butane drop is vaporizing, it absorbs heat from the surrounding water,and the water changes into ice,which attach to the n-butane drop. There are two phase change processes in this phenomenan,I found it difficult ro simulate this process by common fluent model. I want to get some advise about this promble. Thank you!
