| Abstract | The unsteady field induced in a duct by supersonically travelling waves, when analyzed from a 'wave-fixed' co-ordinate system, becomes the problem of supersonic flow over wavy walls. The mean drag on the confined flow due to the waves and its effect on the flow are of interest. It is shown that for a regularly profiled wavy wall the wave strength remains finite according to linear theory at all axial positions; but for the case of a randomly deformed wall the wave energy increases linearly with downstream distance. One can thus deduce that the mean flow would slow down and give up part of its kinetic energy to waves. Equivalently, it is predicted that random supersonic waves would induce strong acoustic streaming in the direction of wave travel. |
