摘要
本文主要对二维情况下温盐浮力比λ为1的温盐均势场的流动情况进行了探讨,对在温盐均势场中不同的流动参数对流场流动的结构所产生的影响作了大量的数值模拟工作。发现在温盐均势场中,即使是给出第一类边界条件,流动仍然存在多种不同的平衡态:出现多胞流的稳定平衡和周期震荡;而且在不同参数下稳定流动的状态和周期震荡的运动周期有较大的差别。
In this paper, our work concentrates on the numerical study of the flow characteristic of the 2-dimensional thermohaline equilibrant system. It is found that there exist several different equilibrium states in this system, which could be multi-cell stable equilibria or the periodic oscillations even when the first kind boundary conditions are imposed on the surface of the box. It is also found that the characteristics of the stable equilibrium states and the periods of the oscillations could be different with the parameters variations.
