Description
Technical field
The present invention relates to a kind of Ship Bubbles Wake field laboratory simulation device, it belongs to simulation and the basin experimental technique field of Ship air wake.
Background technology
During surface vessel navigation, a tail containing a large amount of micro-bubble can be formed at its afterbody.Due to the existence of bubble, compared with the physical features such as sound, light of tail flow field and around common waters, there is significant difference, thus provide good target signature for detection, trackable surface naval vessel.Therefore, Ship Wake Bubble Field properties study has important military and civilian and is worth, and has become a focus in the field such as torpedo guidance, remote sensing.And directly at sea the Bubbles Wake field characteristic of real ship and correlation detection technology are detected and tested, credibility and the regularity that inconvenience, the particularly uncontrollable factor such as sea situation, meteorology have a strong impact on measurement result such as to there is costly, the cycle is long.So simulation produces Ship Bubbles Wake field in the lab, carries out basic research to its physical characteristics and correlation detection technology, it is a kind of approach efficiently.At present, in laboratory, the method for simulation generation Bubbles Wake field mainly contains several as follows.
One, water electrolysis method: the ultimate principle producing hydrogen according to brine electrolysis, the conductive metal sheet be placed in water is connect direct supply anode, tinsel connects negative electrode, produces the bubble hydrogen suitable with wire diameter on the metal filament after energising, and the number density by regulating electric current to change bubble.But the method cannot generate the large scale bubble in the initial wake flow in naval vessel, and energy consumption is huge, a large amount of hydrogen of generation to intersperse among in laboratory easily explosion caused, fire, form potential safety hazard.
Two, chemical reaction method: namely utilize chemical agent and water to react and generate bubble, commonly uses the potpourri of tartrate and sodium bicarbonate proportioning and water vigorous reaction to generate great amount of carbon dioxide bubble at present.But the yardstick that the method generates bubble is wayward, and chemical agent is difficult to intersperse among in water rapidly and uniformly, may be formed isolated " air pocket " that bubble is one by one intensive, cannot the equally distributed Ship Bubbles Wake field of simulated bubble.
Three, micropore air-jet method: pressure gas is directly sprayed in water by porosints such as micropore ceramics and forms a large amount of bubble.But the method generates the diameter of bubble and is difficult to be less than 300 μm under hydrostatic condition, therefore this method can only generate the bubble compared with large scale in the initial wake flow in naval vessel, and the medium-long range Ship Bubbles Wake field that backwash homing torpedo mainly detects cannot be simulated.
Four, negative pressure inhalation: by custom-designed hydrofoil rapid movement or water body flow in water, aerofoil produces local decompression, produces microbubble after sucking outside air.But the yardstick of the more difficult control bubble of the method and number density.
Said method, except there is respective deficiency, also has a common shortcoming, namely only creates the bubble in wake flow and cannot simulate the flow field that Ship Motion produces.But in actual Ship Wake, the kinetic characteristic, retention time, Diffusion Law etc. of Ship Wake field of turbulent flow on microbubble that the factors such as screw propeller discharge currents, Field around Ship Hulls and ship wave making produce all have appreciable impact.Therefore, be simulation Ship Bubbles Wake field more true to nature, Bubble Field and the field of turbulent flow of Ship Motion generation must be considered.
Summary of the invention
The invention provides a kind of Ship Bubbles Wake field laboratory simulation device, be intended to overcome now methodical deficiency, realize the life cycle management of being come into being in Ship Bubbles Wake field, spreading, disappearing, the total factor simulation that Bubble Field, field of turbulent flow organically blend.
The present invention solves the problems of the technologies described above adopted technical scheme: a kind of Ship Bubbles Wake field laboratory simulation device, it comprises a ship model, it also comprises propulsion system, a rudder shape micropore ceramic tube and a feeder, described propulsion system adopt propulsion electric machine to drive screw propeller through transmission shaft, on the ship model at screw propeller rear portion, fixed mount is adopted to hang a rudder shape micropore ceramic tube; Described feeder adopts source of the gas to connect by pressure control valve, gas meter, air supply hose the air supply pipe being arranged in rudder shape micropore ceramic tube successively; Described rudder shape micropore ceramic tube adopts the streamlined structure of hollow and thin-walled, air supply pipe leads to bottom rudder shape micropore ceramic tube internal cavities, micropore ceramics tube wall gather size distribution evenly, the bridge arch shape open pore that is interconnected, when the speed of a ship or plane of ship model is 1m p.s., the aperture of bridge arch shape open pore is 0.05-0.15um, the wall thickness of micropore ceramics tube wall is 12-16mm, and the pressure passing into gas is 0.25-0.35 atmospheric pressure.
Above-mentioned technical scheme generates Ship Bubbles Wake field for simulating.The line style of ship model, the size and dimension of rudder shape micropore ceramic tube, the configuration of screw propeller are according to the object ship design and installation of simulation.Propulsion electric machine provides the power needed for ship model self-sailing by transmission shaft carrying screws, and by regulating propulsion electric machine rotating speed and ship model drinking water, realizes the generation of naval vessel afterbody simulated flow pattern under the different speed of a ship or plane, different loading conditions.Rudder shape micropore ceramic tube is installed on ship model stern rudder blade place by fixed mount.Pressure control valve is equipped with in the outlet of source of the gas, and the gas meter be communicated with successively by air supply hose, rudder shape micropore ceramic tube, to injecting gas in naval vessel afterbody simulated flow pattern, generate a large amount of microbubble, realize the coupled simulation of Bubble Field and field of turbulent flow.The micropore size of rudder shape micropore ceramic tube calculates according to bubble growth rule in flow field to be determined, and in conjunction with Stress control valve regulation supply gas pressure, realizes the control to bubble scale distribution.Regulate gas supply flow by gas meter, realize the control to number of bubbles density.
The invention has the beneficial effects as follows: this Ship Bubbles Wake field laboratory simulation device comprises ship model, propulsion system, rudder shape micropore ceramic tube and feeder.The propulsion electric machine of propulsion system drives screw propeller through transmission shaft, ship model adopts fixed mount spade rudder shape micropore ceramic tube, the source of the gas of feeder connects by pressure control valve, gas meter, air supply hose the air supply pipe being arranged in rudder shape micropore ceramic tube successively, and rudder shape micropore ceramic tube adopts the streamlined structure of hollow and thin-walled.This analogue means overcomes and can only produce Bubble Field and the deficiency cannot simulating afterbody flow field, naval vessel, makes the kinetic characteristic of bubble, retention time, Diffusion Law more similar to the situation in real wash.Simultaneously, by the shear action in flow field, accelerate the disengaging of micropore place bubble, reduce the yardstick that described rudder shape micropore ceramic tube produces bubble, thus overcome existing micropore air-jet method and can only generate deficiency compared with large scale bubble, the bubble scale in the simulated bubble tail flow field of generation is distributed more similar to the situation in real wash.Comprehensively above-mentioned 2 points, the method can be Ship Bubbles Wake field characteristic and correlation detection technology research in laboratory and provides the target more similar to real wash.
