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
rho_{k} << 1
44
\f]
