METHOD AND CAVITY FOR SUPPRESSION OF CAVITY FLOW OSCILLATIONS AND ACOUSTIC LOADS USING CURVED REAR FACE

摘要

Pressure oscillations or acoustic loads over an open type cavity having a front face an upper edge of which constitutes a leading edge and having a rear face an upper edge of which constitutes a trailing edge are reduced by applying curvature to the rear face so as to present a convex curved surface internal to the cavity. In one embodiment, a cross-section through a longitudinal axis of the convex curved surface describes part of an ellipse.
