POM 模式边界条件的数值试验及其在环台湾岛海域风生流模拟中的应用

A Numerical Experimentation on Boundary Condition of POM and its Application to Wind-driven Flow Simulation in the Sea Area Around Taiwan Island of China

通过一个数值试验，对运用 POM 模式做风生流模拟时边界条件的选取方案做了初步的讨论。试验表明，POM"外模式"采用辐射边条件、"内模式"采用辐射方案的改进形式是一种可行的方法；如果用水位作为控制条件，也可以使用辐射边条件。文章同时给出了环台湾岛海域冬、夏风季生流的模拟结果。

： A numerical experimentation is designed to discuss the boundary condition schemes of POM in wind-driven flow simulation. The results show that it is applicable to use normal radiation condition in the external model and to use modified radiation condition in the internal model. If water elevation is used to be the control element, radiation condition can also be applied to water elevation. Based on this work, wind-driven flow in summer and winter of the sea area around Taiwan island is simulated numerically.
