    • A system for fluid processing is provided to control shear, point velocity and pressure in either a Newtonian or non-Newtonian fluid which includes creation of three fields, namely a dynamic microshear field, a dynamic velocity field and a dynamic pressure field, with the fields being created by the injection of energy between 1 KHz and 10 MHz into the fluid. Control is achieved by control of the angle at which mechanical energy is delivered, steering and/or focusing of the energy, control of the amplitude of the energy waveform, of the energy, and control of the frequency of the energy in one embodiment to eliminate standing waves. By controlling the three fields, the system is able to control overall fluid behavior. In one embodiment, energy is injected into a fluid at any angle to the direction of flow assuming the fluid is flowing, with the injected energy providing a predetermined controllable zone of energy in the fluid at the region of energy injection. In another embodiment, the container itself is a transducer that acts as a processor, where the energy comes from the container itself. In a further embodiment, a phased array is used for electronically steering and focusing energy to any point within the fluid volume to provide for the desired shear, velocity and pressure distributions. Note that the direction and focusing of the injection of energy is turnable by physically moving a transducer or by the use of a phased array.
    • 提供用于流体处理的系统以控制牛顿或非牛顿流体中的剪切,点速度和压力,包括创建三个场,即动态微锯齿场,动态速度场和动态压力场,其中场 通过在1KHz和10MHz之间的能量注入到流体中而产生。 控制是通过控制机械能量传递的角度,能量的转向和/或聚焦,能量波形的幅度的控制以及能量的频率的控制来实现的,以消除 驻波。 通过控制三个场,系统能够控制整体流体行为。 在一个实施例中,假定流体流动,能量以与流动方向成任意角度注入流体中,注入的能量在能量注入区域中在流体中提供预定的可控的能量区。 在另一个实施例中,容器本身是用作处理器的换能器,其中能量来自容器本身。 在另一个实施例中,相控阵列用于电子转向和将能量聚焦到流体体积内的任何点以提供期望的剪切,速度和压力分布。 注意,通过物理移动换能器或通过使用相控阵列,可以转换能量注入的方向和聚焦。
