| Outline of Final Research Achievements |
The objective in this study is to investigate the boundary layer flow, and to control the boundary layer transition on the rotating disk by systematizing the effects of the orbital motion on the boundary layer flow. The effects of a disk diameter, orbital speed and orbital direction on the boundary layer flow on a rotating disk under orbital motion are found from the flow of low Reynolds number(laminar flow) to the high Reynolds number(turbulent flow), by the flow visualization using a oil-film technique, the dynamically flow visualization using a smoke-wire technique, and the velocity measurements using a hot-wire anemometer.
