25 Application
26     buoyantBoussinesqSimpleFoam
28 Description
29     Steady-state solver for buoyant, turbulent flow of incompressible fluids
31     Uses the Boussinesq approximation:
32     \f[
33         rho_{eff} = 1 - beta(T - T_{ref})
34     \f]
36     where:
37         \f$ rho_{eff} \f$ = the effective (driving) density
38         beta = thermal expansion coefficient [1/K]
39         T = temperature [K]
40         \f$ T_{ref} \f$ = reference temperature [K]
42     Valid when:
43     \f[
44         rho_{eff} << 1
45     \f]
