Effect of monochromatic 'frozenin' velocity pulsations of the external flow on a laminar boundary layer
Abstract
The problem of the effect of an individual small harmonic velocity perturbation in the external flow on the flow in a laminar boundary layer on a flat plate is examined. The susceptibility problem is investigated in the framework of the boundary layer equations as well as in the framework of the OrrSommerfeld equation. In th first case, numerical and analytical distributions of the amplitudes of 2D velocity pulsations with respect to the boundary layer thickness are obtained. In the second case, numerical distributions of the amplitudes of 2D and 3D velocity pulsations with respect to the boundary layer thickness are obtained.
