Description
Technical field
This utility model belongs to wave flume experimentation field, a kind of for studying the device of water particle motion track under wave action.
Background technology
Along with the development of science and technology, the mankind explore the paces of ocean and are also burning the wind.
21
Century will be full-scale development epoch of utilizing ocean, and ocean to be developed is necessary for recognizing ocean, this significance just determining research wave motion and urgency.Wave is the kinetic factor that immediate offshore area all kinds of works in river mouth cannot be avoided, wave action be in all kinds of structure design, construction and maintenance process must faced by physical phenomenon.Therefore, the research of wave motion is that we develop ocean and coastal resources, protect the marine environment and must understand in depth.Owing to the water particle motion characteristic in wave motion directly determines the wave current load of works, hot issue the most of concern.
Key to wave motion research is to observe the omnibearing speed of wave in real time, there are some researches show, when object is impacted by wave, the impulsive force producing maximum injury is not the velocity of wave of surface traveling but by the speed i.e. current speed of wave internal water particle, even if disaster-stricken body vulnerability is the least, it is also difficult to avoid the wave disaster caused by wave internal water particle.In the design process of ocean engineering, it is often necessary to the parameter of various marine hydrometeorologies is carried out statistical analysis, and wherein wave motion parameter is as a kind of important hydrologic parameter, is the most necessary for some ocean engineering.Wave observation data in ocean is limited, tends not to meet the demand of ocean engineering.
The observation of wave is confined to utilize marine marker to gather the macroscopic view wave motion characteristic such as wave height and velocity of wave by forefathers more, but does not has related art method to be observed the motion conditions of current and wave combined flow internal water particle.And the motion conditions how observing current and wave combined flow internal water particle is claimed by existing progress already.
Water particle spike refers to that the tracer utilizing artificial manufacture, to substitute water particle, with the movement locus of the instrument shooting tracers such as video camera, then carries out deep analysis according to the track of tracer to the motion of water particle.Understand according to existing research theory, comprise the wave motion characteristic of spread speed and water particle speed, determine the size of seaway load, closely related with wave disaster.But owing to the definition of conventional wave is only relevant with wave height, do not consider the impact of kinetic characteristic, and limited to the observation method of velocity of wave translation field, cause people to the understanding deficiency of wave motion characteristic and to pay attention to not.Therefore, it is badly in need of a kind of effective observation device and measures the tracer of water particle motion under wave action for directly perceived.
Utility model content
For solving above-mentioned technical problem, this utility model provides a kind of for studying the device of water particle motion track under wave action, and it has clearly showed that the position of wave internal water particle, the beneficially movement locus of intuitive judgment wave internal water particle.
For realizing above-mentioned technical purpose, the concrete technical scheme that this utility model is taked, a kind of for studying the device of water particle motion track under wave action, including tank, it is respectively arranged wave simulator in the internal two ends of tank and wave suppression arrangement, the suspension being placed in tank and the trace particle of several different colours being scattered in suspension, wherein trace particle and suspension isodensity.
Further having, the cell body of tank is marked with graduation mark.
Further having, tank is to be made by transparent plexiglass plate.
Further having, described trace particle is spherical or column solid particle.
Further having, described trace particle is to be prepared from by polystyrene material.
Further having, wave suppression arrangement includes that several vertical racks stand on the thin plate within cell body and the porous media being distributed between thin plate, spaced set between thin plate and thin plate.
Beneficial effect
Replaced the motion of water particle by the motion of trace particle, the motion of abstract water particle is embodied intuitively, thus reach to probe into the purpose of water particle motion track under wave action.The trace particle of different colours can be placed at different water levels in the process used, the most both the water particle motion track under same wave height, the same depth of water, different depth can have been probed into, it is also possible to probe into the water particle motion track under different wave height, the same depth of water, the same degree of depth.This device not only can be used to probe into water particle motion track under wave action intuitively, and simple structure low cost, easy and simple to handle.
