The experiment is conducted at subcritical Reynolds numbers for the linear instability of plane Poiseuille flow. The non-dimensional wavenumber of the corrugated wall is 1.02 and the amplitude is 4% of the channel half height. It is shown that such a slight waviness of the wall surface reduces the critical Reynolds number down to about 4000., 資料番号: NALSP0059015, レポート番号: NAL SP-59}, title = {波状壁をもつ2次元チャネル流の安定性の実験的研究}, year = {2003} }
