Detailed Description

Transient solver for buoyant, turbulent flow of incompressible fluids, with optional mesh motion and mesh topology changes.

Original source file buoyantBoussinesqPimpleFoam.C

Uses the Boussinesq approximation:

\[ rho_{k} = 1 - beta(T - T_{ref}) \]

where: \( rho_{k} \) = the effective (driving) kinematic density beta = thermal expansion coefficient [1/K] T = temperature [K] \( T_{ref} \) = reference temperature [K]

Valid when:

\[ \frac{beta(T - T_{ref})}{rho_{ref}} << 1 \]
