| Research Abstract |
The flutter and mixing characteristics of the flexible rubber sheet cantilevered at the leading edge in a ducted flow are investigated based on the experiments in the low speed and supersonic wind tunnels and the numerical simulations. The results are obtained which show the relations among the flutter limits, the flutter frequency and flutter amplitudes. Moreover, the mixing enhancement due to the fluttering rubber sheet is confirmed. All the results indicate that the flexible sheet cantilevered at the leading edge is available for the vortex generator in various flows.
