摘要

2016)抽象。本文从理论上研究了双流体系统中传播内波的Boussinesq方程。假定双流体系统被两个刚性板所包围。首先导出了三个方程，其中三个主要未知量分别为上、下流体在任意高度处的界面位移和两个速度势。最优BEs的确定需要一个深度参数的解，该解可以通过对色散关系应用pad近似得到唯一解。对最优BEs预测的一些波的性质进行了检验。优化后的模型不仅扩大了传统电磁法的适用范围，而且为内波的研究提供了新的视角

Boussinesq equations for internal waves in a two-fluid system with a rigid lid

2016) Abstract. A theoretical study of Boussinesq equations (BEs) for internal waves propagating in a two-fluid system is presented in this paper. The two-fluid system is assumed to be bounded by two rigid plates. A set of three equations is firstly derived which has three main unknowns, the interfacial displacement and two velocity potentials at arbitrary elevations for upper and lower fluids, respectively. The determination of the optimal BEs requires a solution of depth parameters which can be uniquely solved by applying the Padé approximation to dispersion relation. Some wave properties predicted by the optimal BEs are examined. The optimal model not only increases the applicable range of traditional BEs but also provides a novel aspect of internal wave
