The Heat Power PropertyManager lets you apply heat power to the vertices, edges, faces, and components. The specified value is applied to EACH entity. For example, if you apply a heat power of 1,000 Watts to a vertex, 2 faces, and a component, the total heat power applied is 4,000 Watts. The value of the heat power can be positive or negative. A positive value indicates heating and a negative value indicates cooling (heat absorption). Heat power is used for thermal studies only.
To define heat power:
Do one of the following:
In the COSMOS AnalysisManager tree, right-click Load/Restraint and select Heat Power.
-or-
Click COSMOSWorks, Loads/Restraints, Heat power.
-or-
Click Heat
Power
(COSMOSWorks Thermal Loads toolbar).
The Heat Power PropertyManager appears.
In the graphics area, select the desired vertices, edges, faces, and components.
Under Heat Power, do the following:
Set Units
to the desired unit system.
Type a value for the
Heat power
in the selected unit system.
To define a time-dependent heat power, click
Use Time Curve
then
click Edit to import or define a time
curve. The value of the heat power at any time instant is calculated
by multiplying the specified heat power value by the corresponding Y value
of the time curve.
To define a temperature-dependent heat flux,
click Use Temperature Curve
then click Edit to
import
or define a temperature curve. The value of the heat power
at a given temperature is
calculated by multiplying the flux value by the corresponding Y value
of the temperature curve.
To control the heat power condition by a thermostat, do the following:
Click Thermostat (Transient).
Click in Sensor
(select a vertex)
and select the location of the
thermostat.
Make sure to first click
in the Sensor (select a vertex)
box before selecting a vertex for the sensor. Otherwise, the selected
vertex appears in the Selected entities
box.
Select the unit for the Lower
bound temperature
and type the desired value in
the value box.
Select the unit
for the Upper bound temperature
and type the desired value in the value box.
Click
.
The specified value is applied to each selected vertex, edge, surface, and component.
