• Visualization of Large-scale Flow Structures in a Three-dimensional Wall Jet

抄録

This study is to clarify the flow structure of a three-dimensional wall jet discharged tangentially on a flat surface from a circular nozzle. Instantaneous pattern of the secondary flow was visualized by tuft-grid methods, and the feature of the large-scale structures existed in the present wall jet was examined. It was revealed from cross-section views that the streamwise vortices with the scale as large as that of the jet height were dominant structures, and that these vortices were moving quasi-periodically toward the outside. And also, a surface flow was visualized with the depth-tuft grid. A dynamic behavior of the streamwise vortices was excellently shown in terms with the tuft image reconstructed at x/d ?? 40 and its two-dimensional spectrum.
