Nonlinear and Nonparallel Stability Problems.
Abstract
An analysis was developed describing the spatial parallel flow development of disturbances that are introduced into an incompressible laminar boundary layer by a vibrating ribbon at the wall. The dominant mode is corresponding to the eigenmode of the flow at the ribbon frequency, as found by Gaster, but the solution technique does not require the questionable assumptions previously invoked. Analysis of the Compressibility introduces additional complexities, including the stagnation enthalpies of the two streams, and admits influences of higher acoustical modes. Keywords: Compressible free shear layers.
