Create a two-sided stream on edges
This example shows how to create a two-sided stream on edges.
Click Home tab→Loads and Conditions group→Load Type list →Thermal Stream .
Set the following:
Type = Two-Sided Stream on Edges
Name = Stream 7
Selection Type (Path Selection — Side A and Path Selection — Side B groups) = Polygon Edge
Select the first (1) and last (2) polygon edges to specify the stream path on side A.
In the Path Selection — Side B group, click Select Object and, in the graphics window, select the first (1) and last (2) polygon edges to specify the stream path on side B.
Make sure that the stream direction is in the same direction for sides A and B.
Set the following:
Fluid group
- Fluid Material = Air
Stream Conditions group
Mass Flow = 0.9880 kg/sec
Inlet Temperature = 666.42 C
Pressure = 0.0493 N/mm^2(MPa)
Heat Transfer — Side A group
- Heat Transfer Coefficient = 150 W/m^2-C
Heat Transfer — Side B group
Use same Heat Transfer as Side A check box =
Heat Transfer Coefficient = 175 W/m^2-C
Click OK.
