As the development of wave energy was limited by low wave energy density conditions in China, a wave gathering channel with a trumpet-shaped opening was proposed to improve the wave energy density in the channel. The projection length of the wave gathering channel on the center line was defined as the characteristic scale. By using combination of Star-CCM+ numerical simulation and model experiment, the effect of wave gathering on the device under different ratio of the characteristic scale and incident wavelength was studied. Results show that the effect of wave gathering is best achieved when the incident wavelength is 2 times of the characteristic scale under the condition that the inlet and outlet width of the contraction section are certain, and the wave height increases by 53.12%.Compared to the mode of gathering waves relying on special terrain, the wave gathering channel is not limited by topography, which is helpful to improve the applicability of the wave power generation device in the low energy density sea area around our country.
