FVConvectionCorrelationInterface

Computes the residual for a convective heat transfer across an interface for the finite volume method, using a correlation for the heat transfer coefficient.

The surface convective flux to the fluid is then: with the surface convective heat flux, the heat transfer coefficient defined by the correlation as a material property and the temperature of the adjacent solid and fluid.

Example input file syntax

In this example, a cold fluid is flowing next to a centrally-heated solid region. The heat diffuses through the solid region, and convection at the interface transfers the heat to the fluid.
