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

Analysis of the thermal plumes in turbulent Rayleigh–B´enard convection based on well-resolved numerical simulations;; by M. KACZOROWSKI and C. WAGNER

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.
