Class
Foam::coupledMultiphaseTemperatureFvPatchScalarField
Description
Mixed boundary condition for the phase temperature of a phase in an
Euler-Euler multiphase simulation, to be used for heat-transfer with another
region in a CHT case. Optional thin wall material layer resistances can be
specified through thicknessLayers and kappaLayers entries.

The new tutorial case tutorials/modules/CHT/multiphaseCoolingCylinder2D is a
variant of the coolingCylinder2D case in which a 10% oil droplets in water
mixture flows over and cools a hot cylinder. The case in run with the
foamMultiRun multi-solver executor.
