TransAT Tutorial Manual 5.1. Particles in Crossflow

Defining a sub-boundary condition (SubBC)
• Select Ymin in the drop-down list at the top of the BCs tab and highlight YMIN0 in the
surface tree

• Click to create a subBC. The button is visible next to the other buttons once Ymin 0 is
selected.
• There are two horizontal and two vertical scroll bars in the Sub BC window. Move the
horizontal scroll bars to define a 0.01 m long sub BC around the middle of the Y-min
boundary in the X-direction ( i.e. X min =0.045 to X max =0.055m).

• Click

• Set the newly created boundary YMIN 0 1 to be an inflow. To do so

– Click
– Rename newbc0 to Inflow part
– Select Inflow in the drop-down list of the Type column

– Click
– Fill in the inflow properties:
∗ Inflow Data Source: From BC
∗ Inflow Type: Velocity based
∗ Inflow profile: Constant
∗ Inflow Velocity Components: u: 0.0 v: 0.87 w: 0.0
∗ In the Lagrangian Particle Tracking tab:
Particle Volume Fraction: 2.0e-3
Particle Temperature: 400.0

• Click to save the settings and close the window

• Assign the Inflow part boundary condition to the YMIN0 1 surface
The mesh is now ready.

• Click Files then select Save to save the settings
