项目摘要
In this research work, hyperbolic free boundary problems have been treated. The basic equation expresses a model for peeling off a tape from a plane. Based on this model, we established a new method analyzing bubble motion on water surface or small droplet motion with dynamic contact angle on obstacle. In the case of everal attached bubbles, we developed an efficient algorithm which can automatically deal with moving junctions including topological changes. On the ther hand, we have constructed a numerical solver for the problem of bouncing elastic shell via the discrete Morse flow method. Using this algorithm, we are able to incorporate inner structure and analyze the interactionbetween the shell and its contents.
在这项研究工作中,双曲自由边界问题得到了解决。基本方程表达了从平面上剥离胶带的模型。基于该模型,我们建立了一种分析水面上气泡运动或障碍物上动态接触角小水滴运动的新方法。对于总是附着气泡的情况,我们开发了一种有效的算法,可以自动处理移动结点,包括拓扑变化。另一方面,我们通过离散莫尔斯流方法构建了弹性壳弹跳问题的数值求解器。使用该算法,我们能够合并内部结构并分析外壳与其内容之间的相互作用。
