regarding buoyantBoussinesqSimpleFoam

Hello Friends,

I am working on a problem of heat transfer of flow in Pipe. For that purpose I am using

buoyantBoussinesqSimpleFoam. I want to remove buoyancy term in the solver how should I

identify these term.

Regards

Hi,

why not just set g = 0?

If you really want to modify the solver it mostly in pEnq.H file.

Hello,

The easy way is to just put value for g vector as (0 0 0) in constant/g file.

I got the answer. just need to make beta zero in properties........because buoyancy

term in momentum equation is correlated to kinematic density = 1-beta(T-To)
