    摘要: A method and apparatus for managing a flow of a fluid. The fluid is received at an input port (206) of a structure (204). The fluid is sent through a chamber (210) in communication with the input port (206). The fluid is caused to flow from the chamber (210) and out of an output (208) port in a direction that changes with a frequency based on an application of pressure pulses in the chamber (210).

    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: Briefly described, the present invention is concerned with cooling heated bodies and/or heated fluid with synthetic jet actuators in either open or closed systems. A first preferred embodiment of a cooling system of the present invention comprises a synthetic jet actuator directed to impinge directly on a heat producing (or heated) body. The synthetic jet actuator generates a synthetic jet stream comprised of cool ambient fluid that impinges on the heated surface thereby cooling this surface. As an example, the heated surface/body could be a microchip array in a microcomputer. After coming into contact with the heated surface, the fluid moves along the surface and is finally rejected to the ambient where it mixes and cools down. The synthetic jet may be incorporated into a modular unit that may be clipped on to a circuit board or other heat producing element to provide added, 'ad hoc' cooling. In another configuration, a synthetic jet actuator may be positioned, relative to the heated surface, to create a synthetic jet stream to flow along the heated surface. In this embodiment, the flow would be approximately tangential to a surface of a heat producing body. This embodiment may further comprise a cyclical flow of the fluid jet, along the heated body and about a heat sink surface.
