two energy equations in Fluent
Hi
I try to modeled arc burning discharge, and i didn't know how to introduce two temperature or energy equation, one for electrons and for heavey species in Fluent. if you have any suggestion answer me. Thant's louiza 
I don't know how you intend to model this phenomenon, but , as far as I know in fluent, you can add scalar transport equations and species transport equations, not extra energy equations.

my question is: in the case when i suppose two different temperatures for a species and another for heavy electrons (no LTE), how to define two equations of energy in Fluent see equation 1 and 2 
Your equations contain mixed derivatives, and I'm not sure how to implement those. But, as I said before, you have to use either scalar transport equations or species transport equations. I'm not aware of any way to implement extra energy equations, maybe for multiphase flows with eulereuler approach... but is a long shot.
