碩士 / 逢甲大學 / 水利工程與資源保育學系 / 102 / Tsunami simulation by combining immersed boundary method and level set method to resolve the flow problems between the free surface and structures. Respectively, in space and time discretization using the fifth-order WENO method and the third-order Runge-Kutta method to calculate the function of , and then solve the pressure Poisson equation such that the continuity equation satisfies.
This research considers two kind of tsunami causing conditions to divide into case one and case two. Case one is a rigid rectanglar body sliding into water and case two is a rigid triangular body sliding down an incline. Observe interaction between the free surface and rigid structures under two different situations. Case three to five are model simulations of solitary wave in which generated solitary waves process as tsunami propagates by using 2D numerical simulation. When solitary wave contacts different structures, the free surface will run up along the slope or even run over the top of structure. For investigating aforementioned phenomenon, setting several observation points to measure solitary wave height and print out the data, and then applying graphics software to present the result of 2D numerical simulation.
Key words: immersed boundary method, level set method, free surface, WENO method, Runge-Kutta method, solitary wave
