碩士 / 國立成功大學 / 水利及海洋工程學系碩博士班 / 98 / This paper presents a Smoothed Particle Hydrodynamics (SPH) method which is used to simulate the solitary wave mechanics. The SPH method is a Lagrangian description of flow field coordinates and mesh free approach. First of all, this article introduces the method of SPH theory and explains the modeling application. In the present case, the validation of initial condition and the wave profile have been verified, and then present model is used to simulate a solitary wave moving over a uniform depth and running up a vertical wall. The result shows that when the ratio between wave height and water depth over 0.3(A0/d > 0.3), the numerical solution of solitary run-up will higher due to strong nonlinear effect. The result agrees well with the experiment.
Finally, present model is employed to simulate a solitary wave through a 1:20 sloping seawall. The case of solitary wave which is non-breaking passes sloping seawall in different wave conditions. The computing results show that when different solitary passing through seawall, the form of wave flow will change into a jet flow or flow through the seawall along the dike surface.
