Abstract :
*(250~1000 words)
The entrance of the shiplock is a transition region which always exist a mixing shear layer caused by the flow of the main rive and the still water of the approach channel. The flow structure of the turbulent mixing area at the entrance presents as large-scale vortices frequently and periodically. And the turbulent fluctuations induced by the separation of large-scale vortices at the entrance area affects the navigation condition unavoidable. The existing studies usually regard the mixing shear layer as a steady flow and only take care of the average velocity, and it would underestimate the harm of the unsteady characteristics of the shear flow. A lot of field observations show that there is an obvious water surface wave caused by the vortices. This paper uses RNG k-ε model to study the hydraulic characteristics of the entrance. The vortex characteristics and its effect on the oscillation of water level and velocity are analyzed. Results show that LES model has an advantage for an accurate simulation of vortex compared with RNG k-ε model. And it can be seen that the vortex generates at the upstream of the shear zone, then develops with the flow until it disappears. The maximum vorticity is always located at the downstream junction of the main flow and the approach channel. The shear vortex causes the period change in the oscillation of flow velocity and water surface and the oscillation direction of the water surface is parallel to the flow velocity direction. All the above provide references for hydraulic characteristics of the navigation conditions.
