Stereoscopic Flow Visualization

---

Stereoscopic flow visualization is being used to investigate the structure and evolution of a low Reynolds number turbulent boundary layer. The boundary layer has a Reynolds number based on momentum thickness of 700. The research is being carried out by Carl Delo, under the direction of Professor A.J. Smits. You will need anaglyph glasses (the kind with red and blue lenses) to see the 3-D effect. The images are in JPEG format. If your web browser cannot load the images, the presence of an application such as JPEGView on your system is necessary. For best results, you should turn on image auto-loading, and adjust your viewing window so that the 600 pixel wide scale below is centered.
