二次元縮流筒の平面壁における逆遷移

抄録

This paper presents an experimental study of reverse transition occurred in the boundary layer flow along a flat plate placed at the center of two-dimensional symmetrical contraction. The experiments were carried out in the contractions of three kinds: Cheers, cosine and WITOSZYNSKI types. the reverse transition was examined based on the velocity profile, thickness and turbulence of the boundary layer along the flat plate. The results were discussed in comparison with those of existing in vestigations.
