Description
Technical Field
The invention belongs to the technical field of water flow wave-absorbing devices, and particularly relates to a bidirectional multiple wave-absorbing device and a use method thereof.
Background
The wave water tank is an important place for carrying out wave related research, and has limited length due to the limitation of experimental places, when waves propagate to the closed end of the water tank, the waves can touch the end plate to be reflected, and the reflected waves reciprocate between the wave making plate and the boundary to form secondary and repeated reflected waves. The reflected waves continuously interfere with the waves set by the experiment and are mutually overlapped to form a very complex wave system, and if the reflected waves cannot be effectively eliminated, the flow field around the experimental model can be seriously affected. The wave-absorbing device is an important device which is arranged at the end part of the wave water tank and used for reducing wave energy and preventing reflected waves from affecting test results.
The wave-absorbing effect of different wave-absorbing devices is different, and the accuracy of the wave water tank test can be directly influenced by the quality of wave-absorbing performance. Wave-absorbing devices used in current wave water tanks can be divided into arc-surface wave-absorbing devices, wire-mesh-array wave-absorbing devices, box-type wave-absorbing devices and slope-type wave-absorbing devices according to geometric shapes. For the sink with a fixed depth, the arc surface wave-absorbing device has a good wave-absorbing effect. However, the arc surface wave-absorbing device has an optimal water depth with the best wave-absorbing effect, and once the water depth in the water tank deviates from the optimal water depth, the device cannot achieve the good wave-absorbing effect. The wire mesh array wave-absorbing device has a good wave-absorbing effect on a water tank with fixed wave wavelength and wave height. However, for the wire grid array wave-absorbing device, the air permeability is not changed along the path, so that the wave-absorbing device cannot achieve an effective wave-absorbing effect on the premise of small occupied space, the wave-absorbing principle of the box-type wave-absorbing device is the same as that of the wire grid array wave-absorbing device, and the wave-absorbing defect same as that of the wire grid array wave-absorbing device is also present. The slope type wave-absorbing device is made of broken stone and bamboo branches as the most common materials, and the wave climbing and water body are utilized to generate vortex motion in the porous materials to consume energy, so that the wave-absorbing effect is better as the slope is flatter. Although the wave-absorbing device has a simple structure, the wave-absorbing device has some disadvantages: the wave-absorbing device occupies too large space, has poor wave-absorbing effect, and causes broken stone to pollute water bodies.
In order to eliminate the reflection influence of the waves as much as possible, it is necessary to improve the structure of the existing wave-absorbing device to overcome the above-mentioned drawbacks.
