|
Description
|
|
Transient solver for buoyant, turbulent flow of incompressible fluids
|
|
|
|
Uses the Boussinesq approximation:
|
|
\f[
|
|
rho_{k} = 1 - beta(T - T_{ref})
|
|
\f]
|
|
|
|
where:
|
|
\f$ rho_{k} \f$ = the effective (driving) kinematic density
|
|
beta = thermal expansion coefficient [1/K]
|
|
T = temperature [K]
|
|
\f$ T_{ref} \f$ = reference temperature [K]
|
|
|
|
Valid when:
|
|
\f[
|
|
rho_{k} << 1
|
|
\f]
