buoyancy and species transport
 

I want to study species dispersion using a mixture of species. But I want also to introduce thermal effects (by heating a wall for example) using the boussinesq approximation. but I saw that it is not possible to use boussinesq and species transport.... so, how can I consider buoyancy forces and species transport? thanks

Re: buoyancy and species transport
 

Why do you want to use the boussinesq approximation? Just use the (incompressible) ideal gas law. That's all you have to do.
