It adds equations for the heat rates Pp1 and
Pp2 and the temperatures
Tp1 and
Tp2 at the connecting ports
p1 and
p2 of the component, and defines the following relation between the heat rate
P and the temperature difference
ΔT:
where Rconv (SI unit: K/W) is the thermal resistance, which is defined from the surface
Area A and the
Heat transfer coefficient h as
Enter a Component name for the convective thermal resistor. The prefix is
CR.
Set the two Node names for the nodes connected by the convective thermal resistor. Note that the ports
p1 and
p2 correspond respectively to the solid wall and fluid regarding the evaluation of the temperature.
Set the Area A of the surface of the convective heat rate and define the
Heat transfer coefficient h used to express the convective thermal resistance. The default option is to enter a
User defined value for the
Heat transfer coefficient h.
When From material is selected, choose a material available from the
Materials list.
See the Fluid feature for details about the settings related to each correlation.
Set the Absolute pressure,
pA. For
User Defined, enter a value or expression. Else, select an
Ambient absolute pressure defined in an
Ambient Properties node under
Definitions. The pressure is used to evaluate the
Fluid material properties and this setting is not available for the
Transformer oil and
Water options.
Finally, when the Fluid is
Moist air, also set the
External relative humidity,
, and the
Surface relative humidity,
, used to evaluate the material properties.
Select appropriate options in the Add the following to default results in order to include the following global variables (space-independent) in the default plots:
