Title: | 含渦流作用之重力水波研究(1/2) | Authors: | 黃良雄 | Keywords: | gravitational water wave;vortex;boundary integral equation method;vortex method;numerical simulation | Issue Date: | 2004 | Publisher: | 臺北市:國立臺灣大學水工試驗所 | Abstract: | In this study, a grid-free numerical model for the simulation of gravitational water wave with vortex effect is proposed. The computational algorithm is established by combining a potential flow field with a vortex flow field. The potential at the free surface and the free-surface displacement are solved by the time integrations. The vorticity field is the solution of the vorticity equation, which is solved using the vortex method and the vortex sheet method. The potential and velocity fields are solved by the boundary integral method. Up to the present we have finished the establishment of mathematical formulations, the numerical models about potential flow and linear wave, and the numerical tests of vorticity generation from solid boundary. The unfinished parts are the numerical tests of vorticity generation from free surface, model integration, verifications and applications. |
