| Abstract: | The Herbert theory 1, 2] of laminar turbulent transition is generalized by taking into account the development of the secondary disturbances with allowance for their higher harmonics. The results of calculations of the development of three-dimensional pulsations, based on this theory, are in a agreement with the Herbert results in the initial stage of development and with the results of direct numerical modeling, obtained in this paper, and with experiment 3] in the later nonlinear stages of transition.Translated from Izvestiya Rossiiskoi Akademii Nauk, Mekhanika Zhidkosti i Gaza, No.6, pp. 3–9, November–December, 1993. |
