| description | This work is of a fundamental nature and is devoted to the study of the influence of distributed suction through a finely perforated hydrodynamically smooth surface on natural and acoustically enhanced boundary layer perturbations under conditions of predominantly non-separated flow. The issue of the minimum necessary suction for suppression of perturbations is considered. The results obtained give grounds to assert that the efficiency of distributed suction in terms of suppressing the growth of disturbances is due not only to the reattachment of a separated flow, but, in general, to a change in the stability parameters of the flow. |
