Description
Technical field
The utility model patent is related to fluid dynamics experimental rig technical field more particularly to a kind of flow pattern generator.
Background technology
In multiple Ministry of Industry such as the energy, power, nuclear reactor, petrochemical industry, metallurgy, environmental protection and aerospace
Door, multiphase flow are all widely used.The distribution situation of each phase medium of multiphase flow is known as flow pattern, and flow pattern is different, multiphase flow
The performances such as flowing, heat transfer, mass-transfer performance, electric shock imaging are different.The research of each flow pattern performance is studied depending on polyphase fluid experimental
The performance of device flow pattern generator, therefore in Simulation of Multiphase Flow process of experimental, produce flowed needed for experiment to greatest extent
Type is most important.In Simulation of Multiphase Flow device, flow pattern generator is the core component of the device most critical, the direct shadow of performance
Ring the generation quality of each flow pattern of polyphase fluid experimental.Therefore, rationally good flow pattern generating means is the important of flow pattern experimental study
Component part, and effective flow pattern generator should can to greatest extent, as comprehensive as possible generate flow pattern needed for experiment.
Flow pattern generating mode in existing flow pattern generator is roughly divided into three kinds, i.e. mechanical dissection mixed phase, fluid eddy flow mixes
Conjunction and spray dispersion.Mechanical dissection mode, due to block so that poromerics from playing one's part to the full, along with inflation or
(pressure) increase can directly contribute bubble, the increase of vacuole size when injecting liquid；Fluid mixed-forming was mixed using air-liquid
Journey premixes liquid, gas is ground into bubble, and Air Bubble Size depends primarily on liquid turbulence level and lasting incorporation time, and most
Reach eventually and maximum system energy state phase.The mode of this generation flow pattern is relatively easy, but during mixing, it is not easy to
The morphological feature of the reverberation liquid such as bubble, vacuole in fluid is held, is not easy to the descriptions such as the accurate qualitative, observation of flow pattern；Jet stream
Molding is then that liquid is first become dispersed phase, then gradually becomes continuous phase with the increase of pressure, gas is then continuous by
Mutually gradually it is dispersed into microvesicle.It is compared compared with first two fluid molding mode, the above two experienced by fluid mixing and bulla is broken
The process of vesicle is broken into, and the latter is then by directly mixing fully dispersed direct formation Stable Manifold.But the generation pair of flow pattern
More demanding in laboratory equipment, forming process is relative complex, while generating process is extremely complex, generation flow pattern is relatively single,
It is unfavorable for laboratory research work.
The modes such as direct-injection, the jet stream that experiment is used with flow pattern generating means, both modes are higher to Laboratory Request, i.e.,
It needs larger experimental site that can not minimize arable land change, is unable to reach ideal requirement.Generating process is extremely complex,
Generation flow pattern is relatively single, is unfavorable for the development of laboratory research work.
