32 Description
33  Steady-state solver for buoyant, turbulent flow of incompressible fluids.
34 
35  Uses the Boussinesq approximation:
36  \f[
37  rho_{k} = 1 - beta(T - T_{ref})
38  \f]
39 
40  where:
41  \f$ rho_{k} \f$ = the effective (driving) density
42  beta = thermal expansion coefficient [1/K]
43  T = temperature [K]
44  \f$ T_{ref} \f$ = reference temperature [K]
45 
46  Valid when:
47  \f[
48  \frac{beta(T - T_{ref})}{rho_{ref}} << 1
49  \f]
