Stabilization of flow over an attachment line using a near-wall body force

Abstract

The problem of the control of steady flow in the vicinity of the attachment line on the leading edge of a swept wing is considered. It is assumed that the control is realized by means of near-wall body force action for the purpose of increasing the flow stability. The stability problem is solved under the assumption of the streamwise homogeneity of the undisturbed three-dimensional flow. The dependence of the stabilizing effect on the action amplitude and the width of the region, where the near-wall force is applied, is studied.
