Hello Flow Simulation gurus.

I would like to model heat transfer through body tissue or colloidal suspensions (such as gelatin) that basically consist of a solid-water matrix. As heat is applied, some of the water evaporates and changes the thermal and physical properties of the material. I would like to obtain the time-dependent temperature change through the material as a hot electrode is applied to a local area. Any idea how to approach this to get a realistic model? I am assuming I wil have to input table/curve data for the tissue or colloid thermal and physical properties. Do you know of any sources of thermal properties of body tissues? How to handle the changing water content? Any suggestions are welcome!
