WCNSFVInletTemperatureBC
Defines a Dirichlet boundary condition for finite volume method.
There are three options for specifying the inlet temperature of the system:
specifying a temperature postprocessor
specifying an energy flow rate postprocessor, a mass flow rate postprocessor and a specific heat capacity functor. The functors are usually a functor material property, defined by a GeneralFunctorFluidProps. The scaling factor can be used to account for projections if the inlet flow and the surface are not aligned.
specifying an energy flow rate postprocessor, a mass flow rate postprocessor, a specific heat capacity and a density functor. The functors are usually a functor material property, defined by a GeneralFunctorFluidProps. The scaling factor can be used to account for projections if the inlet flow and the surface are not aligned.
This boundary condition works with postprocessors, which may be replaced by constant values in the input. The intended use case for this boundary condition is to be receiving its value from a coupled application, using a Receiver postprocessor.
Specifying the inlet temperature using a WCNSFVInletTemperatureBC
will not preserve energy flow at the boundary in most cases, in part because of the discretization error. Specifying an incoming energy flux using a WCNSFVEnergyFluxBC is currently the only conservative approach.
Example input syntax
In this example input, the inlet boundary condition to the energy conservation equation is specified using two WCNSFVInletTemperatureBC
. The inlet temperature is specified using an energy and a mass flow rate postprocessors.
