Abstract
Detailed investigation in the crossflow field on a rotating disk boundary-layer have been done and complicated three-dimensional (3-D) flow structure and turbulent transition process in the crossflow instability field were greatly clarified by using both hot-wire measurement and an effective flow visualization technique. Taking into account of obtained local fine structure in the transition field, an unique suction system is manufactured, and the flow field is measured applying suction. Results showed that limited delay of the onset of transition is observed. Present suction system can be applied to more practical 3-D boundary-layer flow on swept wings and spinning bodies.
