Reattaching Flow Downstream of Leaf Gate
Measurements have been made of the mean velocities and wall pressures downstream of a blockage simulating a partially closed leaf gate, and the extent of recirculation has been formed. Altogether, six plates are used, the ratios of the heights of the plates to the depth of the duct being in the range 0.161 to 0.833. The Reynolds number based on the height of the plate is typically 105. The pressure fluctuations are related to the velocity fluctuations. Maximum intensities of pressure and velocity fluctuations coincide in a shear layer extending parallel to the duct wall. Peak rms value of pressure fluctuations occurs at a point 0.6 to 0.8 times the distance of reattachment. The significant difference between the reattaching flow and the periodic wake past a bluff body in a two-dimensional stream is indicated.
