buoyant pimple foam

hi
i want to anderstand in which problems buoyant pimple foam uses?
and in "hot room" problem we dont have any inlet flow or outlet flow how flow creation in this problem?

since "No inlet and outlet" in your configuration, why not incompressible solver ?

Hi,

this is an excerpt from buoyantPimpleFoam.C

Code:

Application
    buoyantPimpleFoam

Description
    Transient solver for buoyant, turbulent flow of compressible fluids for
    ventilation and heat-transfer.

    Turbulence is modelled using a run-time selectable compressible RAS or
    LES model.

In hotRoom tutorial flow is created by buoyancy force as gas is heated from below (heat source is set by setFields).

hi, so could you tell me where I can find the governing eqs for "buoyantPimpleFoam"? 3q.

Code:

$FOAM_APP/solvers/heatTransfer/buoyantPimpleFoam/*Eqn.H
