The Taylor hypothesis images are intimately related to the vorticity distribution since the streak lines were visualized by dye issuing from the surface of the cylinder, i.e., the generation surface of the vorticity. In order to clarify the relation between the Taylor hypothesis image and vorticity distribution, the vorticity distribution based on Taylor hypothesis was obtained from the time series data of the velocity past a bubble generating wire determined by hydrogen bubble techniques. Some misleadings of the vortex structure in interpreting the patterns of streak lines were reviewed., 資料番号: AA0001655026, レポート番号: NAL SP-40},
