MINI-TUFT IMAGES

1st AIAA CFD High Lift Prediction Workshop

Some Trap Wing mini-tuft images for Config 1 (slat 30, flap 25) are given on this page. These are from the NASA Ames 12 Foot Pressure Tunnel Test 60. This test was conducted in early 1999. Several caveats:

• These images are from a different tunnel than other experimental data provided on this site.
• These images are also at somewhat different conditions: they are for Mach=0.15 and Reynolds numbers of 3.5 million (run 165).
• The alpha given in each image is the uncorrected alpha, i.e. wall corrections have not been applied to the angle-of-attack number printed in the photo. The corrected alpha is listed above each photo.

These images should be used only to gain a qualitative sense of the state of the near-surface flowfield over the flap for the particular workshop cases.
 

Corrected angle-of-attack = 1.8 deg:

Corrected angle-of-attack = 6.5 deg:

Corrected angle-of-attack = 11.0 deg:

Corrected angle-of-attack = 15.5 deg:

Corrected angle-of-attack = 20.0 deg:

Corrected angle-of-attack = 24.0 deg:

These images have been compressed to fit on the web page. To see larger images, download the following (tarred gzipped) directory containing these jpg files: TuftImages.tar.gz, and view them using your own software.
