摘要: A theoretical model of the disturbances generated by vibrations streamlined surface in boundary layer is discussed. The analysis was performed with aid expansion solution eigenfunctions linearized Navier-Stokes equations nonparallelism flow a real taken into account. High efficiency excitation Tollmien-Schlichting (TS) waves has been found.
