Double-plate internal solitary wave making device and method

Abstract

The invention relates to a double-plate internal solitary wave making device and method. The device is characterized by comprising a density stratification water groove, an upper pushing plate, a lower pushing plate, two sets of transmission mechanisms and a control terminal, wherein the upper and the lower pushing plates are arranged on the cross section of the water groove; the widths of the upper and the lower pushing plates are equal to the width of the water groove; the two sets of transmission mechanisms are connected with the upper pushing plate and the lower pushing plate respectivelyand are controlled by the control terminal; and the control terminal is used for driving the upper and the lower pushing plates to move reversely and horizontally with respective speed, acceleration and travel by changing the transmission ways of the transmission mechanisms. By adopting the device and the method, parameters such as waveforms, amplitudes, wave widths and the like of the internal solitary waves can be controlled, the controllability of the waveform parameter is realized, and the repeat of the internal solitary waves of the same waveform becomes probable.

Description

technical field [0001] The invention relates to a wave-making device, in particular to a double-plate internal solitary wave wave-making device with controllable wave-making parameters and a wave-making method thereof. Background technique [0002] In the actual ocean, the temperature, salinity, and density of seawater vary with space and time, which will generate solitary waves in the ocean that affect the safe operation of underwater vehicles and ocean engineering structures. The stratified flow test tank is the main equipment for studying the characteristics of solitary waves in the ocean, and the simulation of solitary waves is the main technical condition for experimental research. There are many ways to generate internal solitary waves in internal wave test tanks. The existing internal solitary wave wave-making technologies mainly include pumping plate type, vibrating table type, paddle disturbance type and gate type, etc. The basic principle of these wave-making tec...

AI Technical Summary

Problems solved by technology

However, these wave-making technologies have defects: the application of "disturbance" is artificial, the process is difficult to control, and is usually determined by the experience of the operator, so it is difficult to stably control the size and duration of the disturbance to generate wave parameters that can be controlled. Controlled internal solitary waves, it is also difficult to generate internal solitary waves with repeatable waveforms
