CAFV(Computer Aided Flow Visualization) system for the gas dynamics has been developed. The flow field is visualized using LIF of I 2 seeded in Ar and monitered by high sensitive vidicon camera. Image data from vidicon camera at many different visualized planes are stored up in personal computer in order to estimate three-dimensional information on the entire flow field. For the purpose of removing the noise, one frame data is accumulated many times and averaged. This system is applied to two flow fields, i.e., the free jet expanding into a vacuum chamber and the interacting flow field between a skimmer and the free jet. The contour lines of fluorescence intensity on each flow field are depicted effectively.
