Radiative heat exchange element
Extends from Interfaces.TwoPort (Partial model invoking two bondgraphic connectors).
Information
The bondgraphic radiative heat exchange element is a directed TwoPort element. It inherits the effort and flow variables from the directed TwoPort. The specific radiation constant and the radiating surface are modeled as parameters.The radiative heat exchange element has two causality strokes at the element.
Potential variables: e1: Bondgraphic effort variable of inflow f1: Bondgraphic flow variable of inflow, normalized positive for flows into the model e2: Bondgraphic effort variable of outflow f2: Bondgraphic flow variable of outflow, normalized positive for flows out of the model Parameters: sigma: Specific radiation constant (default value = 1 W/(m2*oK4) A: Radiating surface (default value = 1 m2)
