摘要： The present invention is a dramatic enhancement of the two-fluid atomization art through the discovery of a method of causing resonance between capillary waves in the ultrasound range in a flowing liquid stream and the waves created at the surface of that stream of liquid by an impinging gas stream. In the present invention, the surface of a stream of liquid issuing from the outlet or nozzle of an ultrasonic atomizer is impinged upon by a stream of gas. That impinging stream of gas then develops, at the surface of the liquid stream already sustaining its own wave motion, a flow of gas substantially parallel to the flow of the liquid stream that moves faster than that surface of the liquid stream. The flow of the gas at the surface of the liquid stream moves sufficiently faster than the surface of the liquid stream to generate waves at the surface of the liquid stream. The wavelength of the waves generated by the impinging gas on the surface of the liquid stream are modulated by velocity control of the impinging gas stream and resonate with the liquid stream waves. The resonance results in an atomization wherein the droplets are smaller and the droplet size distribution is reduced over prior art ultrasonic atomizers.
摘要翻译：本发明是通过发现在流动液体流中的超声波范围内的毛细管波和通过撞击在液体流表面产生的波之间引起共振的方法，显着提高了双液体雾化技术气流。在本发明中，从超声波雾化器的出口或喷嘴发出的液体流的表面被气流撞击。然后，在液体流的表面已经保持其自身的波浪运动的情况下，这种气体流产生大致平行于液体流的流动的气流，其比液体流的表面更快地移动。在液体流的表面处的气体流动比液体流的表面移动足够快以在液体流的表面产生波。由撞击气体在液体流的表面上产生的波的波长通过撞击气流的速度控制被调制并与液体流波共振。共振导致雾化，其中液滴较小，并且液滴尺寸分布比现有技术的超声雾化器降低。

摘要： The present invention comprises a nozzle type atomizer with two or more aligned “horn” stages. The definition of a “horn” stage is well known in the prior art as an effectively half wavelength length and a tapering shape with a central conduit. The present invention uses two to five, or more, horn stages integrally attached end to end. The dramatic improvement in amplitude of the vibration at the tip of the nozzle is without precedence in the prior art. The present invention makes application of transducer vibration at greater than 200 kHz possible. The present invention reduces the required applied energy for generating the necessary amplitude at the tip by the discovery of amplitude multiplication with two or more horn stages.
摘要翻译：本发明包括具有两个或多个排列“喇叭”级的喷嘴型雾化器。 “喇叭”阶段的定义在现有技术中作为有效的半波长长度和具有中心导管的锥形形状是众所周知的。本发明使用两到五个或更多个一体地并排连接的喇叭台。在现有技术中喷嘴尖端的振动振幅的显着改善是不优先的。本发明使传感器振动的应用可能大于200kHz。本发明通过发现与两个或多个喇叭级的幅度相乘来减少用于在尖端产生必要幅度的所需的施加能量。
