ChtMultiRegionFoam
Solver for steady or transient fluid flow and solid heat conduction, with conjugate heat transfer between regions, buoyancy effects, turbulence, reactions and radiation modelling.

1 Equations
For each region defined as fluid, the according equation for the fluid is solved and the same is done for each solid region. The regions are coupled by a thermal boundary condition.
1.1 Equations Fluid
For each fluid region the compressible Navier Stokes equation are solved.
1.1.1 Mass conservation
The variable-density continuity equation is
