Natural convection
 
2 Attachment(s)
Hello everybody
I am studying natural convection inside a water tank in the presence of inclined heat source. I am using buoyantBoussinesqPisoFoam as a solver and i am using SST K-W model for turbulence. For vertical heat source, flow is fine and going up (opposite to gravity) after heating. But in case of inclined heat source, flow is coming down(direction of gravity).
I hereby attaching two snapshots for flowvectors. One for vertical heat source and other for inclined heat source.
Please help.

What are the boundary conditions you imposed in your case file?

There appears a problem with the BC from the plots.

Try to elaborate your problem.
