      I interested in turbulent natural convection at U shaped cavity. I spent a lot of time on the laminar state. which turbulence model is used at turbulent natural convection? The rayleigh number is about 10^10. the residual graph is not convergence at Ansys fluent. The U shaped cavity uses boiling water. the cavity description

      Stick to default SST and activate buoyancy effects.

      thanks for the comments amine.I don't understand actually which SST model should ? use? K-omega SST model, transition SST model or detached eddy simulation (DES) SST K- omega turbulent model. the last turbulent model is used mostly in the article.

      The default is K-omega SST model.
