Problems solved by technology

However, the push-plate wave-making method and the shaking-plate wave-making method in the existing physical water tank and the numerical water tank, as well as the boundary wave-making method in the numerical water tank, are difficult to solve the secondary reflection of the wave by the boundary. Can't make waves stably for a long time when reflecting
Source wave generation can eliminate waves on both sides of the tank at the same time, which better solves the problem of secondary reflection of waves under long-term work in the tank. However, source wave generation is a purely numerical wave generation, which is difficult to achieve in a physical tank.

Embodiment 1

[0099] Such as Figure 4 to Figure 6 As shown, the push plate device of the vertical push plate wave-making tank in this embodiment includes side plate 13, bottom plate 12, partition plate 11 and vertical push plate 4, side plate 13 and partition plate 11 are arranged in parallel, and side Plate 13, dividing plate 11, two groove side plates 5 and bottom plate 12 form a closed cavity, vertical push plate 4 is arranged in this cavity, slides between vertical push plate 4 and the inner wall of groove side plate 5 Connected, the vertical push plate 4 can slide up and down along the groove side plate 5, the vertical push plate 4 cannot be higher than the sink bottom plate 2, and the bottom of the vertical push plate 4 is connected with the propulsion mechanism. The outside of dividing plate 11 is provided with water tank 8, and the bottom end of dividing plate 11 is provided with communicating hole 9, and the cavity below vertical push plate 4 is communicated with water tank 8 by c...

Embodiment 2

[0102] The connector in this embodiment adopts a conduit, and fluid is contained in the conduit, and the conduit communicates with the cavity below the vertical push plate through the communication hole at the bottom of the propulsion device. By controlling the amount of fluid in the conduit and the height of the conduit, and then controlling the pressure in the conduit, through the reciprocating movement of the fluid in the conduit, the flow direction of the fluid in the cavity below the vertical push plate is changed, thereby changing the movement of the vertical push plate direction, and finally achieve wave making.

[0103] Others are with embodiment 1.

Abstract

The invention relates to the field of wave generation, and in particular relates to a vertical push plate wave generation method and a vertical push plate wave generation water tank. The method comprises the steps of S1 constructing the vertical push plate wave generation water tank; S2 calculating a wave equation according to the target wave information, and outputting corresponding vertical pushplate motion data; S3 collecting wave information of actual wave generation, and collecting parameters. Regular waves, random waves, solitary waves and Stokes waves are accurately and stably manufactured in a laboratory physical water tank, wave absorption can be achieved at the two ends of the water tank, and secondary reflection of the waves is effectively avoided.

Description

technical field [0001] The invention relates to the wave-making field, in particular to a wave-making method with a vertical push plate and a wave-making water tank with a vertical push plate. Background technique [0002] The research on the interaction between waves and structures is a major topic in the field of ocean engineering. The existing research methods mainly include theoretical analysis, model testing and numerical simulation. However, due to the increasingly complex offshore structure and the deepening of the research problems, the existing theoretical analysis methods are sometimes difficult to meet the actual needs, and the model test and numerical simulation technology have attracted extensive attention. Among them, the wave-making method in the physical tank and numerical simulation It is one of the hot spots that people pay attention to. [0003] The wave-making methods in the numerical tank mainly include the velocity boundary wave-making method, the sour...
