Evaporation of water from solid

guy i am doing a project for that i need to a simulation.For that i need to study about the evaporation water from solid (eg sand) so that cooling can obtained.Can any one tell me to how to do the simulation.

Far too often people jump into CFD, obtain pretty images, and take the results as gospel.

Crack open a notepad and pen, and write down an energy and mass balance instead. It will give you approximate rates of evaporation in a fraction of the time it's going take to set up a complex Fluent phase change simulation. And if you do successfully set up a Fluent phase change simulation, the evaporation rates should be the same as the calculation you've done in a notepad.
