Supersonic Wind Tunnel Schlieren and Surface Flow Visualization - Fall 2009 |
| |
This set of videos shows Schlieren and surface flow visualization of Mach 2.5 supersonic flow over a flat plate with a 5 degree wedge. More videos and images will be released as the research progresses. |

Initial Test of 2" ID Propane/Oxygen Detonation Tube - Spring 2009 |
| |
This video shows a typical detonation test using an atmospheric, stoichiometric mixture of propane and oxygen. The tube is approximately ten feet long, but the test is completed within a few milliseconds. A diaphragm is located between the stainless steel and blue vacuum tank tube sections. The rest of the vacuum tank is located about eight feet from the diaphragm, and since a vacuum is not needed, the hatch has been opened. The second half of the video shows the wave can still be powerful while exiting the hatch. |

Low Speed Wind Tunnel and PIV Imaging - Summer 2008 |
| The first video below shows PIV imaging across the centerline of a flat plate in the low speed wind tunnel test section. First, it shows the seeder injecting particles into the LSWT test section until they are swept downstream as the tunnel is turned on. Next, the seeding system is actuated a few times to show the difference when the seeding system is used. The second video shows a demonstration run of the wind tunnel from outside of the building. It reaches 70% of its maximum rated power (about 50 kW). |

Supersonic Wind Tunnel - Fall 2007 |
This video shows a short test of a new LabVIEW control program for the supersonic wind tunnel. The program maintains a continuous pressure in the plenum chamber, which is needed for accurate test results. |

EMFC - Fall 2007 |
These videos show some initial bench tests of the low speed wind tunnel Lorentz force generator plate. The compilation video shows the activation of the plate using salt water with power on the order of a light bulb. The second video shows the effect of vortex dipoles on a viscous conductive fluid with dye visualization. |

Small Scale Shock Tube - Spring 2007 |
| |
The video below shows a test run of a small scale shock tube designed for an undergraduate lab class. Here, the shock tube runs at Mach 1.6 and exhausts into the silencer. The diaphrams are made from sheets of aluminum foil pressed together, and can be seen as they are blown out of the tube. |
