-
In the Plots window, expand the Plot
list and select Gauge Pressure.1 to display the pressure inside
the duct.
As expected, the inlet exhibits a higher pressure than the outlet. The corners of the
duct also exhibit high local pressures. This indicates that the design creates too
much resistance to the airflow and does not process the air well.
-
Change your selection to Velocity Vector.1 to display the
airflow velocity in vector format.
The velocity is lowest along the boundary layer and in the corners of the duct. While
the velocity at the boundary layer is expected, you can improve the airflow resistance
in the corners of the duct by smoothing the edges.
-
Add streamlines to illustrate the airflow through the duct.
-
From the Results section of the Assistant, click Streamlines
.
-
Expand the Options section, and increase the
Thickness to 5 to increase the
visibility of the streamlines.
-
From the Arrows options, select
Auto-spaced.
-
Click OK.
-
In the Plots window, expand the
Plot list and select
Velocity.1.
The streamlines display the flow path from the inlet to the outlet. Airflow is
laminar at the inlet but becomes mixed as it passes through the duct. This
turbulence is a result of abrupt turns in the duct design. Smoothing the wall's
edges and designing fewer turns could reduce the turbulence and pressure drop
across the openings.
