B}, month = {May}, note = {application/pdf, Oscillatory flow is examined experimentally in a two-dimensional furrowed channel. We show the transition of two-dimensional to three-dimensional flow due to instability of the flow at moderate Reynolds numbers. The critical value of the Reynolds number at the onset of three-dimensional flow strongly depends on the Strouhal number. The fluid motion is found to be most unstable in the limited Strouhal number range of 0.02 to 0.03. Two distinct three-dimensional flows are discovered and their boundary is determined only by the Strouhal number, i. e. St≒0.02., Article, 日本機械学會論文集.
