Defining Boundary Conditions
In the heat transfer analysis step, the convection conditions and fixed temperature at the inlet become active. Specify the convection properties as interactions, since the manifold transfers heat to the surroundings. Specify the temperature condition at the inlet as a boundary condition.
- Double-click the Interactions container in the Model Tree.
-
In the
Create Interaction dialog, set the following properties:
Property Setting Name SURFFILM Step Step-1 Types for Selected Step Surface film condition - Click Continue...
-
In the
Region Selection dialog, select
EXTERIOR and click
Continue...
(If the Region Selection dialog does not appear automatically, click Surfaces... at the bottom right of the Viewport).
-
In the
Edit Interaction dialog, set the following properties:
Property Setting Film coefficient 6.667 Sink temperature 300 - Click OK.
-
Repeat the steps above, this time using the following settings:
Property Setting Name SURFFILM-2 Step Step-1 (default) Type Surface film condition (default) Region FLANGES Film coefficient 333.3 Sink temperature 500
Specify the inlet temperature boundary condition next:
- Double-click the BCs container in the Model Tree.
-
In the
Create Boundary Condition dialog, set the following properties:
Property Setting Name Temp-BC Step Step-1 (default) Types for Selected Steps Temperature (default) - Click Continue...
- In the Region Selection dialog, select INLET and click Continue...
- In the Edit Boundary Condition dialog, set Magnitude to 500 and click OK.
