Airflow Project Goals
Create an adjustment to the current OSU
apparatus in order to create an even and
reproducible air flow.

Background
• Moved the location of the air inlet from the
side of the OSU to the bottom to test
imbalance in flow
– This created air circulation through the center of the
OSU near the test sample, but created a more even
upwards flow on both sides of the OSU

Background cont.
• Want to observe the airflow leaving the OSU
chimney, but with the current configuration
we will need to complete measurement near
the test sample first
• Unable to perform CFD at the FAA TC
• Still looking for uniform flow towards the
sample holder

New Test Setup
• Reticulated foam was
placed inside the
second chamber of the
OSU
• Since it is extremely
porous, starting with
this will give me a
direction to move
towards

Federal Aviation Administration
New Setup with One Plate
Will need to re-take data to confirm high velocities, but flow
directions are matching with previous tests.

Conclusion
• There is still an undesired amount of
downward motion seen in the tested
methods
• Will need to continue to test and find the
most optimal setup
