    • A transducer for converting flow energy to acoustic energy, requiring little or no electrical excitation of the device. Process liquid flows through an orifice into the device, past oscillatory members made of resilient material in a high-Q configuration prone to vibration. The turbulent flow of the process liquid causes the oscillatory members to vibrate and, eventually, to resonate. Acoustic waves propagate from one oscillatory member to another oscillatory member and back, conserving acoustical energy and exerting extreme compression and shear forces on the process liquid. Rarefaction may result in cavitation, resulting in extreme local and instantaneous pressures and temperatures. The device is suitable for applying physical work to process fluid for the purpose of destroying bacteria, homogenization, or promoting sonochemical reactions between fluids.
    • 用于将流能转换成声能的换能器,需要很少或没有电气激励的装置。 过程液体通过孔进入装置,过去由易于振动的高Q构型的由弹性材料制成的振荡构件。 处理液体的紊流导致振荡部件振动,最终产生共鸣。 声波从一个振荡构件传播到另一个振荡构件并返回,保留声能并对工艺液体施加极大的压缩和剪切力。 疲劳可能导致气蚀,导致极端的局部和瞬时压力和温度。 该装置适用于物理工作以处理流体,以破坏细菌,均质化或促进流体之间的声化学反应。
