25 buoyantBoussinesqPisoFoam
28 Transient solver for buoyant, turbulent flow of incompressible fluids
30 Uses the Boussinesq approximation:
32 rho_{k} = 1 - beta(T - T_{ref})
36 \f$ rho_{k} \f$ = the effective (driving) kinematic density
37 beta = thermal expansion coefficient [1/K]
39 \f$ T_{ref} \f$ = reference temperature [K]
