Description
Technical field
The present invention relates to a kind of Ship Bubbles Wake laboratory simulation device, its simulation for belonging to Ship air wake and ship
Pond experimental technique field.
Background technology
, can be in one tail containing a large amount of micro-bubbles of its afterbody formation when surface vessel is navigated by water.Due to depositing for bubble
, there is significant difference compared with common waters around in the physical features such as sound, light of tail flow field so that for detection, trackable surface
Naval vessel provides good target signature.Therefore, Ship Wake Bubble Field properties study has important military and civilian value,
And turn into a focus in the fields such as torpedo guidance, remote sensing.And Bubbles Wake field characteristic directly at sea to real ship
And correlation detection technology is detected and tested, there is inconvenience, the particularly sea situations, meteorology etc. such as costly, cycle length not
Controllable factor has a strong impact on the credible and regularity of measurement result.So, simulation in the lab produces Ship Bubbles Wake
, basic research is carried out to its physical characteristic and correlation detection technology, is a kind of efficient approach.At present, mould in laboratory
Intending the method for generation Bubbles Wake mainly has following several.
First, water electrolysis method：The general principle of hydrogen is produced according to electrolysis water, the conductive metal sheet being placed in water is connect directly
Power anode is flowed, wire connects negative electrode, produce the bubble hydrogen suitable with wire diameter after energization on the metal filament, and by adjusting
Current changes the number density of bubble.But this method can not generate the large scale bubble in the initial wake flow in naval vessel, and energy consumption is huge,
The a large amount of hydrogen produced, which are interspersed among, easily triggers blast, fire in laboratory, constitute potential safety hazard.
2nd, chemical reaction method：I.e. using chemical agent and water reaction generation bubble, at present commonly using tartaric acid and
The mixture of sodium acid carbonate proportioning generates great amount of carbon dioxide bubble with water vigorous reaction.But the yardstick of this method generation bubble is not
It is easy to control, and chemical agent is difficult to rapidly and uniformly intersperse among in water, it is possible to create bubble intensive isolated " air pocket " one by one,
Can not the equally distributed Ship Bubbles Wake of simulated bubble.
3rd, micropore air-jet method：Compressed gas is injected directly into water by porous materials such as micropore ceramics and forms a large amount of gas
Bubble.But the diameter of this method generation bubble is difficult to be less than 300 μm under hydrostatic condition, therefore the method can be only generated the initial wake flow in naval vessel
The bubble of middle large scale, and the medium-long range Ship Bubbles Wake that backwash homing torpedo is mainly detected can not be simulated.
4th, negative pressure inhalation：Move or water body flow, produced on aerofoil by the way that the hydrofoil specially designed is quick in water
Microbubble is produced after local decompression, suction outside air.But the yardstick and number density of the more difficult control bubble of this method.
In addition to it there is respective deficiency in the above method, also one common shortcoming only generates the bubble in wake flow
And the flow field of Ship Motion generation can not be simulated.But in actual Ship Wake, propeller discharge stream, Field around Ship Hulls and ship wave making etc.
The Ship Wake field of turbulent flow that factor is produced has a significant impact to the kinetic characteristic of microbubble, RT, Diffusion Law etc..Cause
This, is simulation Ship Bubbles Wake more true to nature, it is necessary to consider the Bubble Field and field of turbulent flow of Ship Motion generation.
The content of the invention
The present invention provides a kind of Ship Bubbles Wake laboratory simulation device, it is intended to overcome the shortcomings of existing method, real
Now nascent to Ship Bubbles Wake, diffusion, the life cycle management disappeared, the total factor mould that Bubble Field, field of turbulent flow organically blend
Intend.
The present invention solves the technical scheme that is used of above-mentioned technical problem：A kind of Ship Bubbles Wake laboratory simulation
Device, it includes a ship model, and it also includes a power set, a rudder shape micropore ceramic tube and a feeder, institute
State power set and propeller is driven through power transmission shaft using propulsion electric machine, on the ship model at propeller rear portion, hung using fixed mount
One rudder shape micropore ceramic tube；The feeder passes sequentially through pressure-control valve, gas flowmeter, air supply hose using source of the gas
Connection is located at the air supply pipe in rudder shape micropore ceramic tube；The rudder shape micropore ceramic tube uses the streamlined structure of hollow and thin-walled,
Air supply pipe leads to rudder shape micropore ceramic tube internal cavities bottom, and micropore ceramics tube wall gathers that size distribution is uniform, be interconnected
Bridge arch shape open pore, when the speed of a ship or plane of ship model is 1m each second, the aperture of bridge arch shape open pore is 0.05-0.15um, micro-
The wall thickness of hole ceramic vessel wall is 12-16mm, and it is 0.25-0.35 atmospheric pressure to be passed through the pressure of gas.
Above-mentioned technical scheme is used to simulate generation Ship Bubbles Wake.The line style of ship model, rudder shape micropore ceramic tube
Size and dimension, the configuration of propeller are according to the object ship design and installation of simulation.Propulsion electric machine drives spiral by power transmission shaft
Oar provides the power needed for ship model self-sailing, and is absorbed water by adjusting propulsion electric machine rotating speed and ship model, realizes the different speed of a ship or plane, different dresses
The generation of naval vessel afterbody simulated flow pattern under the conditions of load.Rudder shape micropore ceramic tube is installed at ship model stern rudder blade by fixed mount.
The outlet of source of the gas is equipped with pressure-control valve, and the gas flowmeter being sequentially communicated from air supply hose, rudder shape micropore ceramic tube are to naval vessel
Gas is injected in afterbody simulated flow pattern, a large amount of microbubbles is generated, realizes the coupled simulation of Bubble Field and field of turbulent flow.Rudder shape micropore is made pottery
The micropore size of porcelain tube is calculated according to bubble growth rule in flow field and determined, and combination pressure control valve regulation supply gas pressure, real
The control being now distributed to bubble scale.Gas supply flow is adjusted by gas flowmeter, the control to bubble number density is realized.
The beneficial effects of the invention are as follows：This Ship Bubbles Wake laboratory simulation device include ship model, power set,
Rudder shape micropore ceramic tube and feeder.The propulsion electric machine of power set drives propeller through power transmission shaft, using solid on ship model
Determine frame spade rudder shape micropore ceramic tube, the source of the gas of feeder passes sequentially through pressure-control valve, gas flowmeter, air supply hose and connected
The air supply pipe in rudder shape micropore ceramic tube is connect, rudder shape micropore ceramic tube uses the streamlined structure of hollow and thin-walled.The simulation
Device, which overcomes, can only produce Bubble Field and can not simulate the deficiency in naval vessel afterbody flow field, when making the kinetic characteristic of bubble, retaining
Between, Diffusion Law and situation in real wash it is increasingly similar.Meanwhile, by the shear action in flow field, accelerate bubble at micropore
Disengaging, reduce the rudder shape micropore ceramic tube and produce the yardstick of bubble, thus overcome existing micropore air-jet method can be only generated compared with
The deficiency of large scale bubble, makes the bubble scale in the simulated bubble tail flow field of generation be distributed with the situation in real wash more
It is similar.2 points of summary, this method can be that Ship Bubbles Wake field characteristic in laboratory and correlation detection technology research are provided
The increasingly similar target with real wash.
