ConvectiveHeatTransferSideIntegral
Computes the total convective heat transfer across a boundary.
Description
This postprocessor computes the total heat flux by integrating the product of the temperature difference and the heat transfer coefficient over a set of boundaries.
where is the set of boundaries, is the solid temperature, is the fluid temperature, and is the heat transfer coefficient.
This postprocessor is useful for ensuring conservative transfers when Robin boundary conditions are used.
