Three-dimensional diagnostics in air and water by molecular tagging and molecular scattering Conference Paper uri icon


  • 1996 by Princeton University. Published by the American Institute of Aeronautics and Astronautics, Inc. Molecular-based approaches are particularly well suited to three-dimensional flow field diagnostics. Images simultaneously capture a wide range of scales and give both vector and scalar quantities. The diagnostic approaches discussed here include flow tagging by RELIEF and PHANTOMM in air and water, respectively; planar imaging in air with Rayleigh Scattering and Filtered Rayleigh Scattering; and planar imaging in water with Laser-Induced Fluorescence. For the tagging approaches, images can be captured using a stereoscopic camera pair to observe the threedimensional displacement of patterns written into the flow field. In the case of Rayleigh Scattering and Laser-Induced Fluorescence, three-dimensional images are captured by sequential or simultaneous images of planar cross sections through the three-dimensional volume. The visualization of these three-dimensional volume data sets requires transparent reprojection, preferably with partial obscuration and motion, if the full complex structure is to be visualized.
