TransAT Tutorial Manual 3.1. Forced Convection in a Channel with Heated Walls

– Inflow Static Temperature: 300.0

• Click to save the settings and close the window.
The inflow boundary condition has now been created.

• Proceed similarly as above to edit the BCs to the following properties

Name: opflow
Type : Outflow
Properties :
− Outflow Type : Pressure
− Outflow Data Source : From Boundary Conditions
− Outflow Pressure : 0
Name: heatedwall
Type : Wall
Basic :
− Temperature / Heat f l u x choice : Temperature
− Temperature / Heat f l u x value : 310.0

Name: symmetry
Type : Symmetry

Assigning Boundary Conditions:

• Select the XMin in the drop-down list at the top of the BCs tab
• Highlight XMIN 0 in the surface tree

• Check the light grey square at the line corresponding to inflow in the boundary conditions
table

• Click
XMin 0 in the surface tree takes the color of the boundary condition after being assigned.

• Proceed as above to associate the remaining surfaces to their respective boundary conditions
as given below.
Boundary : XMin
XMIN 0: inflow
Boundary : XMax
XMax 0: opflow
Boundary : YMin
YMIN 0: heatedwall
