ABSTRACT

In view of the small flow rate, slow velocity and closed circulation of landscape water, water quality deterioration is easy to occur, the hydrodynamic driving method is selected to treat landscape water. Based on hydrodynamic model, three cases were studied for optimal designing. Scheme 1 and 2 are boundary water inlet and outlet, scheme 3 is internal point water inlet and outlet. Analyze the flow rate of the three schemes, and choose the best scheme more intuitively. In Scheme 1, about 30% of the simulated flow area in the south region has a flow velocity exceeding 0.3m/s. About 50% of the flow rate in the northern region obtained by the simulation of Scheme 3 is greater than 0.30 m/s. By comprehensive comparison, it can be seen that the north region selection scheme 3 and the south region selection scheme 1 have the best effect on the overall flow velocity improvement and can be used as the best scheme.
