FV Interface kernels for two variable diffusion, convection and radiation #17638

Open GiudGiud opened 3 years ago

GiudGiud commented 3 years ago

Reason

Those would be helpful for modeling reactors. For example, in a MSR, provided the right closure relation is used, these interface kernels could capture the various heat fluxes from the coolant to the reflector.

Design

Need n1

Inherit from FVInterfaceKernels
use functor materials

Need n2

disjoint meshes. Lots of ghosting functor work

Need n3

boundary layer treatments for convection (see conjugate heat transfer needs for NS)

Impact

More FV capabilities for modeling heat transfer

in https://github.com/idaholab/moose/pull/17870 we introduced diffusion and convection IKs We don't have a radiation one yet
