Simulating flames from Species Transport
 

Hiya,

It's the first time I'm dealing with heat transfer from a flame combusted using the Species Transport. I realized while simulating that the hot gas is supposed to go upwards due to buoyancy. (It didn't happened in mine)
I'm having a hard time for implementing this concept in Fluent.

Can anyone suggest me how to properly activate the buoyancy effect while employing the k-omega SST turbulence model?

Any help will be greatly appreciated!

Thanks,

Nad
