Summary
The effect of Coriolis acceleration on transition of a rotating Blasius boundary layer has been visually investigated. A flat plate is installed in the small size wind tunnel rotating around the axis parallel to the leading edge. The air flow is visualized by introducing the paraffin mist from the wall slit. The transition of the low pressure side boundary layer was found to be characterized by the turbulent spot, while the pressure side boundary layer was associated with the longitudinal vortex instability. The variation of the boundary layer parameters as well as the velocity fluctuation signals during transition can be well explained by the present visualization results.
