| Research Abstract |
CAFV(Computer Aided Flow Fisualization) system for the gas dynamics has been developed and is applied to analize three dimensional structures of the flow field that is visualized using laser induced fluorescence of I_2 seeded in Ar. The field is visualized by many laser sheets and photographed two dimensionally by a high sensitive vidicon camera. These image data are stored up in a personal computer in order to record three dimensional information on the entire flow field.For the purpose of suppressing the noize, an image datum is an avberage of many frame data. From the image data, the visualized pictures at arbitgrary cross sections (CT; Computer Tomography) are reproducted on the monitor by the personal computer.The propriety and effectiveness of this system are verified through the results applied to two flow fields, i.e., the free jet expanding into the vacuum chamber and an interacting flow field between the skimmer and the free jec.
