Simulation Research on Plain 2-D Numerical Value of Submerged Spur Dike

Abstract:

Starting from the 2-D hydrodynamic equation and according to the feature of sudden change of water depths of front and rear edge for submerged spur dike, put forward the Grid Interface Water Depth Method and research the mathematical model of 2-D water flow for submerged spur dike. A rectangular water tank is designed with length of 30m and width of 1.6m, on one side of which five submerged spur dikes are arranged with length of 0.40m, width of 0.05m, height of 0.06m, and spacing between spur dikes of 0.80m. Use the test data of water tank to verify the 2-D mathematical model of average depth surface. The results show that the mathematical model results basically coincide with the measured data, showing this kind of numerical computation method is feasible.
