Hello Everyone! I am new to the forum as well in using ansys.

I am trying to model evaporative cooling of a local zeer pot refrigerator using 2D model. The geometry has spherical like with two layers of clay and sand+water in between.

The issue is, how do I model evaporative cooling in ansys!

How do I add the material sand +water as well as clay and give it the necessary porosity. As far as I know, fluent doesn't have those features.

Also any advice on the best geometry for this model?

Thank you all in advance.
