FVFunctorConvectiveHeatFluxBC
Convective heat transfer boundary condition with temperature and heat transfer coefficient given by functors.
Description
This boundary condition computes convective heat flux , where is the convective heat transfer coefficient, is the temperature, and is the far-field temperature. Both and are functors, which enables various spatial, variable and other dependences. The domain of the variable can be specified as either a fluid or a solid using the is_solid parameter. For a solid domain, the equation above is applied. For a fluid domain, the negative of the heat flux is applied. This allows for easier implementation of a double Robin boundary condition.
Similar objects: - CoupledConvectiveHeatFluxBC for a similar boundary condition coupled to variables, for finite elements - FunctorThermalResistanceBC for a combined conduction, convection, and radiative boundary condition, with a constant outside ambient temperature
Example syntax
In this example, the FVFunctorConvectiveHeatFluxBC boundary condition forms a convective boundary condition between the fluid and the solid.
