The Heat Flux PropertyManager lets you apply heat flux to the selected faces. Heat flux is used in thermal studies only. For steady state thermal studies, you can define temperature-dependent heat flux. For transient thermal studies, you can define time- or temperature-dependent heat flux, and a thermostat to control the heat flux.
To define Heat Flux:
Do one of the following:
In the COSMOS AnalysisManager tree, right-click Load/Restraint and select Heat Flux
-or-
Click COSMOSWorks, Loads/Restraints, Heat Flux
-or-
Click Heat
Flux
(COSMOSWorks Thermal Loads toolbar).
The Heat Flux PropertyManager appears.
In the graphics area, select the desired faces.
Under Heat Flux, do the following:
Set Units
to the desired unit system.
Type a value for the
Heat Flux
in the selected unit system.
To define a time-dependent heat flux, click
Use Time Curve
then
click Edit to import or define a time
curve. The value of the heat flux at any time instant is calculated
by multiplying the specified heat flux value by the corresponding Y value
of the time curve. This option is available for transient thermal studies
only.
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 flux at
a given temperature is calculated by multiplying the specified heat flux
value by the corresponding Y value of the temperature curve.
To control the heat flux condition by a thermostat, do the following:
Click Thermostat (Transient).
Select a vertex for 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.
