Hi guys!

First of all i want to thank you all for this forum, you already helped a lot.

I'm trying to solve the heat transfer around motorcycle helmet in order to determine how the helmet ventilatition affects the rider in a hot day. I already have a model of the head and the helmet. The rider's skin touches the fabric inside the helmet. His sweat get soaked in the fabric. the air flowing oround the helmet and above the fabric drys it and thats how the vetilation suppose to work.
I have here forced convection , conduction between head and helmet, and sweat evaporation through fabric.
I'm not sure which model to choose. Would you use multiphase or species and discrete phase?

Thank a lot
