26 buoyantBoussinesqSimpleFoam
29 Steady-state solver for buoyant, turbulent flow of incompressible fluids
31 Uses the Boussinesq approximation:
33 rho_{eff} = 1 - beta(T - T_{ref})
37 \f$ rho_{eff} \f$ = the effective (driving) density
38 beta = thermal expansion coefficient [1/K]
40 \f$ T_{ref} \f$ = reference temperature [K]
