| dc.description.abstract | 本論文將新推導出的核函數，並將其應用於半隱式移動粒子法(Moving Particle Semi-implicit( MPS) method)，以模擬具自由液面(free surface)的不可壓縮(incompressible )的Navier-Stokes方程。最後，利用孤立波問題與潰壩問題以驗證程式的正確性。 | zh_TW |
| dc.description.abstract | This study is aimed to combine the newly developed kernel function with the Moving Particle Semi-implicit (MPS) method for simulating the incompressible viscous flow with free surface. The proposed method will be validated by solving the solitary wave and broken dam problems. | en |
