This report details an experiment done to verify the effectiveness of a passive flow control system on a two-dimensional bluff body, blunt trailing edge model in controlling wake dimension and Karman vortex sheds. An earlier experiment by Park, et.al. [1] performed analysis via wind tunnel pressure testing and computerized model to determine the ideal proportions of such a tab design and identi...

This note discusses the flow near the trailing edge of a two-dimensional aerofoil moving at a free-stream Mach number close to unity, for cases where the effects of viscosity are slrall. A qualitative argument, which is supported by experimental evidence, suggests that the local Mach number downstream of the trailing-edge shock waves is approximately independent of tie-stream Mach number, a&rof...

We measured the shape of the BOLD response to visual stimulation in subjects between 7 and 61 years of age. We performed two experiments. In the first experiment, at low temporal resolution (TR = 1 s) and with long stimulus periods, we determined activated voxels in each subject. In the second experiment, at high temporal resolution (TR = 294 ms), we measured the response to an impulse stimulus...

This paper presents results of an empirical study on the flow and noise generated by the trailing edge of a flat plate encountering low turbulence fluid flow. Simultaneous measurements of flow and far-field noise data have been taken in an anechoic wind tunnel at the University of Adelaide. Velocity data about the trailing edge and in the wake have been measured using hot-wire anemometry. These...

The pitching airfoils, applied to the vertical axis turbines and propellers, are critical extract more energy from environment. At retreating side, when airfoil blunt leading edge becomes trailing edge, transition vortex dynamics quite different that at advancing side. goal of present work is investigate evolution over reversed airfoil, with main focus on parametrical effect, including mean ang...
