| Abstract: | The supercritical shock wave was obviously improved with the application of hanged-grid & hanged-plate in the slope-curve channel. The new dissipator is really used in practice and is successful. In this paper, the Doppler-laser velocimeter was employed to measure the velocity field around the hanged-grid & hanged-plate. The stability and uniformity flow appeares. This kind of dissipator has the better dissipated energy ratio and adaptability than those conventional types as increasing roughness under the floor. These experimental results are helpful for learning the mechanism of hanged-grid & deflector plate dissipation. |
