Validation of buoyantBoussinesqPimpleFoam solver
 

I am working on incompressible flows with heat transfer, and in my research problems, small temperature difference allow for Boussinesq buoyancy approximation.

Is there any validation case for the buoyantBoussinesqPimpleFoam solver?

The Rayleigh-Benard convection is common in literature, and I found a DNS in the following paper I was wondering if there is a more popular/ widely used validation case for incompressible flows with heat transfer? Any advise or recommendation is much appreciated.

I have made some studies comparing buoyantBoussinesqPimpleFoam with a solver I implemented. The article is the following:

López Castaño, S.; Petronio, A.; Petris, G.; Armenio, V. Assessment of Solution Algorithms for LES of Turbulent Flows Using OpenFOAM. Fluids 2019, 4, 171

Using the Rayleigh-Benard convection case.

Rayleigh-Benard convection is a classic example, for which you have well-defined scales and analytical formulae you can use for validation. No reason to re-invent the wheel there.
