Problems solved by technology

However, even in the presence of such inhomogeneity and anisotropy, coordinate transformation based water wave collectors are nearly impossible to construct, since they not only require strongly anisotropic water depth distributions, but also require significantly different acceleration of gravity

Abstract

The invention discloses a water wave gathering device and relates to the technical field of water wave energy utilization. The water wave gathering device is applied to a water wave field. The water wave gathering device comprises an annular bottom plate and at least three baffles; the at least three baffles are arranged on the annular bottom plate; the extension lines of the baffles are intersected with the central axis of the annular bottom plate; any two adjacent baffles form a radial slit with equal size; and the effective depth of the radial slit is gradiently reduced from the outer sideof the annular bottom plate to the inner side of the annular bottom plate. The water wave gathering device has the beneficial effect that wave which is propagated along the specific direction only exists in the designed water wave gathering device. The radial slit of the wave gathering device is conducive to reduction of scattering of inner and outer boundaries; the phase position of the wave canbe maintained while perfect transmission can be maintained; and experiment measurement and simulation results verify that the centrality and the invisibility of the two devices.

Description

Technical field [0001] The invention relates to the technical field of water wave energy utilization, in particular to a water wave condenser. Background technique [0002] In marine engineering, the concentration of water waves is essential for coastal protection and wave energy collection. The current utilization of water wave energy is not ideal. One of the reasons is that the waves on the sea level are scattered, which requires the deployment of many energy conversion devices on a large area to collect energy. In this regard, a collector device for water waves may be helpful, it just inherits the concept of conversion optics. The key performance of these devices is usually uneven and anisotropic. The concept of using non-uniform properties to control water waves can be traced back to those early devices with variable depth profiles that can simulate the refractive index profile of the mirage effect. The anisotropic response to water waves is difficult to achieve. Using a...
