Turbulent model for natural convection problems

I am solving Rayleigh-benard convection problem inside a rectangular cavity, with bottom plate constant high temperature , side walls insulated, top plate constant low temperature. Fluid is water.

Which turbulent model is best applicable for this problem ?

    I tend to favour RNG k-e, and others will suggest the k-w model.

    Hehe :) Yes I belong to the ones who will favor omega based approaches here. But at the end I would expect similar results. Much more important is that you account for density variations and you track the mass of the water in the system + Resolving the boundary layer (thermal) as the Pr>1.
