32Description
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]
