Abstract

In this paper, we present a numerical experiment on a new piston-type wavemaker using a recently proposed piston-type wavemaker theory. The theory was primarily derived from the classical Boussinesq equation, based on the Pseudo-parameter Iteration Method (PIM). We first use the new theory to observe low amplitude propagating solitary waves and cnoidal waves, whereby we see the workability and validity of the theory. We further succeed in obtaining the graph of a mean power characteristic, in the range of 0.4 $\leq k h \leq$ 1.0, of the new piston-type wavemaker from the new theory.

一种新型活塞式造波器的数值实验:浅水近似

本文利用最近提出的活塞式造波器理论，对一种新型活塞式造波器进行了数值实验。该理论主要来源于经典的Boussinesq方程，基于伪参数迭代法(PIM)。我们首先用新理论观察了低振幅传播的孤立波和余弦波，由此我们看到了该理论的可行性和有效性。在此基础上，成功地得到了新型活塞式造波器在0.4≤kh≤1.0范围内的平均功率特性图。
