    摘要: Disclosed is a flow element (1) comprising an external side (3) that has a top face (3a) and a bottom face (3b) in relation to the direction of flow, and lateral end sections (5a, 5b) that form the lateral ends of the flow element (1) transversal to the theoretical direction of flow (S). A duct (10) is arranged inside the flow element (1). Said duct (10) encompasses a flow drive with a driving motor and a compressor means which is driven by the driving motor and is disposed in the duct (10). The duct (10) has at least one inlet (11) on the bottom face (3b) and/or on at least one of the lateral end sections (5a, 5b) of the flow element (1) as well as an outlet (12) on the top face (3a) of the flow element (1) in order to influence the flow on the flow element (1). A sleeve (30) that can be rotated by means of the driving motor is located inside the duct (10). Said sleeve (30) has at least one cavity (33) which can be made to at least partially overlap with the outlet (12) on the top face (3a) of the flow element (1) in a specific rotational position of the sleeve (30) such that the air that is compressed by the compressor flows through the cavity (33) of the sleeve (30) and the outlet (12). A high-lift system comprising such a flow element is also disclosed.

    摘要: 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).

    摘要: The present invention provides a system and method for actively manipulating and controlling aerodynamic or hydrodynamic flow field vortices (32) within a fluid flow (14) over a surface (16) using micro-jet arrays (10). The system and method for actively manipulating and controlling the inception point, size and trajectory of flow field vortices (32) within the fluid flow (14) places micro-jet arrays (10) on surfaces bounding the fluid flow (14). These micro-jet arrays (10) are then actively manipulated to control the flow behavior of the ducted fluid flow (14), influence the inception point and trajectory of flow field vortices (32) within the fluid flow (14), and reduce flow separation within the primary fluid flow (14).
