27 Description
28  Transient solver for buoyant, turbulent flow of incompressible fluids
29 
30  Uses the Boussinesq approximation:
31  \f[
32  rho_{k} = 1 - beta(T - T_{ref})
33  \f]
34 
35  where:
36  \f$ rho_{k} \f$ = the effective (driving) kinematic density
37  beta = thermal expansion coefficient [1/K]
38  T = temperature [K]
39  \f$ T_{ref} \f$ = reference temperature [K]
40 
41  Valid when:
42  \f[
43  \frac{beta(T - T_{ref})}{rho_{ref}} << 1
44  \f]
