| 内容記述 | It is possible to control the spread of a plane jet passively by the vortices from a two-dimensional cylinder installed in the nozzle contraction. In a particular condition of cylinder placement, two distinctive spectral peaks at frequencies f1 and f2 with their averaged frequency at 1/2 the vortex shedding frequency fv were observed, where the jet exhibits flapping motion at low frequency f3 (= f1-f2). The vortex structures in a plane jet under inharmonic excitation were studies by means of hotwire and phase ensemble-averaging techniques. The phase ensemble-averaging results show that the vortex street shed at frequency fv/2 was formed in the jet under inharmonic excitation, and similar vorticity distributions appeared in the upper and lower shear-layers alternately at frequency f3. As the result, within the duration of one flapping motion, successive nine vortices were formed at shedding frequency fv/2 to complete their one cycle of evolution. | |||||||||||
