    • A method and mechanism of producing a suction and periodic excitation flow. The method includes providing fluid flow from jet port with diameter dl at a controlled input pressure (Pin), directing the flow to a conduit with diameter d2, >d1, allowing additional fluid to join the flow through suction slot(s) to create an amplified flow in the conduit, further directing the amplified flow in a first direction by applying a transverse pressure differential, further redirecting the amplified flow in another direction by modifying an angle by which the transverse pressure differential is applied and iteratively repeating the further directing and further redirecting so that the amplified flow oscillates between the directions. The suction and periodic excitation flows may be employed, for example, to effectively control boundary layer separation. A mechanism for automated performance of the method is also disclosed.
    • 产生抽吸和周期性激发流的方法和机理。 该方法包括在受控的输入压力(Pin)下提供具有直径d1的喷射流体的流体流动,将流引导到具有直径d2,d1的导管,允许附加流体通过抽吸槽连接流体,以产生 通过施加横向压力差来进一步引导放大的流动在第一方向,通过修改横向压力差被施加的角度并且反复地重复进一步的指导和进一步的方向 重定向,使得放大的流在方向之间振荡。 可以采用吸入和周期性的激发流,例如有效地控制边界层分离。 还公开了一种用于自动执行该方法的机制。
