- flow_channelName of flow channel component to connect to
C++ Type:std::string
Unit:(no unit assumed)
Controllable:No
Description:Name of flow channel component to connect to
- q_wallSpecified wall heat flux [W/m^2]
C++ Type:FunctionName
Unit:(no unit assumed)
Controllable:No
Description:Specified wall heat flux [W/m^2]
HeatTransferFromHeatFlux1Phase
This component is a single-phase heat transfer component that uses a wall heat flux from a user-provided function.
Usage
The user must supply the name of the connected flow channel via the parameter "flow_channel".
The parameter "P_hf" is optional and specifies the heated perimeter ; if unspecified, this is computed from the cross-sectional area assuming a circular cross section.
The parameter "Hw" is optional and specifies the heat transfer coefficient ; if unspecified, it is computed using the selected closures. Note that depending on the type of heat transfer and the chosen closures, it may not be relevant.
The parameter "q_wall" specifies the wall heat flux function .

Advanced Parameters
Formulation
In general, a single-phase heat transfer adds some heat flux term to the energy equation:
where is a heat flux at the flow channel wall, and is the heated perimeter.
