Summary
The laminar-turbulent transition of a three-dimensional boundary layer was studied experimentally using a thin radial liquid-film flow along a stationary and rotating disk, and with a linear stability theory. Because of the very small liquid-film thickness of the flow, a disturbance growing near the wall produces an uneven liquid surface. Hence, the process of transition and the radius of the point of transition could be easily observed through the features of the liquid surface. It was found that two different types of instability, viscous and inflectional, may appear, and that the weak three-dimensionality of the mean flow suppresses the transition due to viscous-type instability, whereas the strong one promotes it due to inflectional-type instability.
