    • This invention relates to a method of controlling vortex bursting on an aerodynamic surface (20) associated with separated flows and, in particular, relates to control of separated flows over aerodynamic or hydrodynamic surfaces (20) that may have highly swept leading edges (26). A method of controlling vortex bursting on an aerodynamic surface or a hydrodynamic surface (20) is provided, the surface (20) comprising a gas source (22) located on or in the surface (20) and the method comprising the step of repeatedly operating the gas source (22) thereby to eject a flow of gas into an airflow passing over the surface (20). Effective control of the frequency at which the gas source (22) is operated has been found to reduce pressures on the surface (20) caused by vortex bursting. The present invention also provides a synthetic jet actuator (22) and an aerodynamic or hydrodynamic surface (20) comprising a plurality of such discrete synthetic jet actuators (22).
    • 本发明涉及一种控制与分离流相关联的空气动力学表面(20)上的涡流爆裂的方法,并且具体地涉及对可能具有高度扫过的前缘(26)的空气动力学或流体动力学表面(20) 。 提供了一种控制空气动力学表面或流体动力学表面(20)上的涡流爆裂的方法,所述表面(20)包括位于所述表面(20)上或其中的气体源(22),并且所述方法包括重复操作 所述气源(22)由此将气流喷射到在所述表面(20)上方通过的气流中。 已经发现有效控制气体源(22)工作的频率可以降低由涡流破裂引起的表面(20)上的压力。 本发明还提供一种合成射流致动器(22)以及包括多个这种离散合成射流致动器(22)的空气动力学或流体动力学表面(20)。
