| 概要 | First paper on the stability of a shear layer between two parallel uniform streams, whose velocity distribution is erf-function. In the former half inviscid fluid is discussed by means of polynomial a...pproximation, dividing the half domain of existence 0≦y<∞ into three sub-domains. Instability is exhibited only by antisymmetrical oscillations, the wave number of neutral stability being a little larger than 1. In the latter half we concern with cases of finite Reynolds number and employ the method of expansion by means of Hermite functions. To see the pertinence of our method inviscid flow is treated again by this procedure, results according well with the former ones. Stability curve given by our method seems satisfactory except when the Reynolds number is small and shall be the subject of next paper.続きを見る |
