    • The invention is a method and apparatus for generating vortex rings in a fluid medium. The apparatus is immersed in a body of water and includes first and second bodies. Gas is fed into a concave surface of the first body via a conduit from a finite or infinite supply source. As gas is supplied to the concave surface a single unitary bubble is formed therein. When the volume of the gas in the concave surface has attained the volume of the concave surface, the unitary bubble travels as a single unit to an exit aperture. A vacuum is formed between the two bodies when the unitary bubble enters the exit aperture. This vacuum functions to pull the entire unitary bubble through the aperture. Following departure from the exit aperture, a toroidal shaped bubble is formed.
    • 本发明是用于在流体介质中产生涡流环的方法和装置。 该设备浸入水体中并且包括第一和第二体。 气体通过有限或无限供应源的导管进入第一体的凹面。 当气体被供应到凹面时,在其中形成单一的单一气泡。 当凹面中的气体体积达到凹面的体积时,单一气泡作为一个单元行进到出口孔。 当整体气泡进入出口孔时,两个物体之间形成真空。 该真空功能可以将整个单一的气泡拉过孔。 在离开出口孔之后,形成环形泡沫。

    • An apparatus and method are described that allows for the production of vortex-ring bubbles in a host liquid. A simple embodiment of the device consists of an inverted cup with a short nozzle protruding into it through the center of its end face. Circular plates are fixed to both open ends of the nozzle tube, which itself is positioned such that its lower end is at a higher level than the open end of the inverted cup. When cup is immersed in a liquid, open end down, and the inside of the cup is pressurized with an inflow of gas, a confined volume of gas will form inside the cup, and the liquid level in the cup will fall, and peel away from the nozzle lower end plate. The gas is exposed to the open lower end face of the nozzle, but does not enter the nozzle until the pressure has built up within the cup sufficiently to break the surface tension meniscus at the nozzle inlet. The gas then self accelerates up through the nozzle and rapidly exits at the upper end of the nozzle tube. The confined liquid level in the cup rises back up in response and enters the nozzle in a unique self-siphoning action shutting off further gas flow out the nozzle. The exiting gas bubble self organizes into a gas-filled, vortex ring. Alternatively, the exiting flow of gas can be captured in a second conical nozzle and buoyantly directed to the throat of the nozzle where it undergoes the same self acceleration and self siphoning to form a vortex ring at the throat exit. Other different embodiments of the device that all operate under the same method of intermittent breaking of surface tension forces followed by self acceleration and self siphoning to generate a vortex ring bubble are described. The advantages of the device are that it is mechanically simple, easy to manufacture, has no moving parts, will not wear out, and does not require any operator intervention in order to function.
    • 描述了允许在主体液体中产生涡环气泡的装置和方法。 该装置的简单实施例包括具有通过其端面中心突入其中的短喷嘴的倒杯。 圆形板固定在喷嘴管的两个开口端上,喷嘴管本身被定位成使得其下端处于比倒杯的开口端更高的水平。 当杯子浸在液体中时,开口端向下,杯内部用气体流入加压,杯内将会形成有限量的气体,杯中的液面会下降,并剥离 从喷嘴下端板。 气体暴露于喷嘴的开放的下端面,但是不要进入喷嘴,直到压力已经在杯内积聚起来,足以破坏喷嘴入口处的表面张力弯液面。 气体然后通过喷嘴自身加速,并在喷嘴管的上端快速离开。 杯子中的限制液面响应而升高,并以独特的自吸虹吸作用进入喷嘴,从而将进一步的气体流出喷嘴。 排出的气泡自身组织成充满气体的涡环。 或者,排出的气体流可以被捕获在第二锥形喷嘴中,并且浮力地指向喷嘴的喉部,在喷嘴的喉部处经历相同的自加速和自吸,以在喉口处形成涡环。 描述了所有装置的其它不同的实施例,其全部在相同的表面张力的间断断裂方法下运行,随后是自加速和自吸虹墨以产生涡流环气泡。 该设备的优点是机械简单,易于制造,没有移动部件,不会磨损,并且不需要任何操作员干预才能起作用。

    • The present invention provides an adjustable pulsed gas agitator comprising a gas accumulation chamber with a gas discharge pipe, a gas supply unit, and an adjustable gas discharge unit. The adjustable gas discharge unit comprises an elongatable gas pipe slidably disposed over the lower part of the gas discharge pipe, and a gas cap disposed underneath the elongatable gas pipe; so that when the adjustable gas discharge unit is moved upward or downward, the volume of the stirring gas accumulated within the gas accumulation chamber is decreased or increased; thereby the frequency and strength of the discharged pulsed gas flows is varied.
