TL;DR: In this article, the authors demonstrate that an oscillating water column of given dimensions can be made to resonate at any chosen frequency of interest by controlling the phase of the load acting on it.

TL;DR: In this paper, the nonlinear free surface effects inside the oscillator, as well as a simplified model for nonlinear damping effects at the outlet, are introduced, and the solution of the problem is shown to be quite dependent on the non-linearities and shows response similar to a Duffing oscillator with a hardening spring.

TL;DR: In this article, the authors proposed a new methodology based on the three dimensional source ditribution method, which distributed the source to the device and the thin & light plate in "water column", and from the behaviour of this plated, the power and the pressure in water column are calculated.
Abstract: Due to the structural complexity and the mutual interference of "water columns", the estimations of absorption power for a large wave energy conversion devices of flosting type in ocean could not achieve the desired results. Thus, in this paper the authors will propose a new methodology based on the three dimensional source ditribution method. We distributed the source to the device and the thin & light plate in "water column", And from the behaviour of this plated, the power and the pressure in water column are calculated. But, yet method should be proved to be valid by experiment.

TL;DR: In this article, the wave power absorption of an oscillating water column with rectangular geometry is studied within linear theory, where the column is assumed to be placed in an infinitely wide, partially reflecting wall.
