Laminar denstity stratified flow
 

Hi,

I'm searching for suitable governing equations and BC's (model) for uncompressible, viscous, laminar, steady but density stratified flow. Density stratification means that there is a density gradient at domain inlet prescribed.

Thanks for suggestions

Hallo,
incmpressible-does it mean that density gradient is perpendicular to flow direction in a whole area? I have seen a system of equations where density stratification is caused by source terms, but I am unable to find it8(
