چکیده
The Huangchigou Water Distribution Hub is the core water distribution structure in Hanjiang-to-Weihe Valley Diversion Project. It plays a decisive role ensuring safety of downstream transport, allocating reasonably and reducing waste abandoned water. study on its unsteady-flow hydraulic characteristics key significance formulation for opening closing rules hub gates. shape instantaneous surface profile an important factor unsteady flow hub. effect traditional level measurement method not ideal. A single-camera fixed-scale compensation proposed observation. meets requirement accuracy reduces observation cost model test. test Southern Main Tunnel was carried out under two operating conditions when 0.0246 m3/s. Precise data such as wave front propagation velocity oscillation recovery time flows obtained. has reference value research design transfer dispatching gate-opening gate-closing Hub.

Flow Characteristic of Hydraulic Headbox Based on Complementary Pulp Distribution
In order to study effect of complementary pulp distribution, computational fluid dynamic (CFD) was used to research flow characteristic of hydraulic headbox based on complementary pulp distribution. Mass flow rate out of mixing chamber and velocity distribution at slice of headbox were experimented. The results showed that because of simplified design, there were a little gradient of velocity a...
