摘要： A system and method for controlling the surface and/or volume of a digital clay device is provided. One embodiment, among others, is a method comprising the following steps: determining a desired position of a skeleton structure portion residing in the digital clay device, determining a volumetric change of fluid residing in a fluid cell, the determined volumetric change corresponding to the determined desired position of the skeleton structure portion, opening a valve so that the fluid flows through the valve thereby causing the determined volumetric change of the fluid, and adjusting a position of the skeleton structure portion corresponding to the desired position of the skeleton structure portion, the position adjustment caused by a force generated by the fluid cell on the skeleton structure portion when the volume of the fluid cell changes in response to the determined volumetric change of the fluid residing in the fluid cell.

摘要： The present invention involves a system for altering the aerodynamic shape and/or fluid flow about a solid body. The preferred embodiment comprises an obstruction disposed on the solid body and extending outwardly from the solid body into the fluid flowing over the solid body and a synthetic jet actuator embedded in the solid body such that said fluid flowing over the solid body encounters the obstruction before the synthetic jet actuator. The synthetic jet actuator includes a jet housing defined by walls, the jet housing having an internal chamber with a volume of fluid and an opening in the jet housing connecting the chamber to an external environment having the fluid, and a volume changing means for periodically changing the volume within the internal chamber so that a series of fluid vortices are generated and projected in the external environment out from the opening of the jet housing. A synthetic jet stream is formed by the fluid vortices entraining the fluid of the external environment and is projected outwardly from the solid body. The fluid flowing over the solid body contacts the synthetic jet stream forming a recirculation region, thereby modifying both the flow field and the pressure distribution and similarly modifying both the lift and drag characteristics of the solid body.

摘要： The present invention involves micromachined synthetic jet actuators, or “microjet” actuators. These fluidic control devices may be fabricated using standard silicon micromachining techniques and comprise an orifice situated atop an actuator cavity which is bounded at least partially by a flexible membrane. Alternatively, microjets may be formed in more robust substrates, such as metals or ceramics. Vibration of the membrane using either electrostatic or piezoelectric drives results in a turbulent air jet formed normal to the microjet orifice. The jet stream is synthesized by a train of vortex rings. Each vortex is formed by the motion of the diaphragm and is advanced away from the jet under self-induced velocity. Alternatively, the microjet actuator can comprise a “piston in cylinder” to take the functional place of the vibrating diaphragm. This can be accomplished by changing the aspect ratio of the actuator cavity to a deeper, more cylindrical shape. A piston-like actuator can then be realized by using a “bossed” diaphragm. An improvement to microjets is the use of modulators with the jet actuators. Modulators are generally devices to selectively cover and uncover the orifice of a synthetic jet actuator in order to prevent either flow into or out of the jet cavity. Such modulators are fabricated as either vertical drive, lateral drive or constricting modulators.

摘要： Synthetic jet actuator, which can be micromachined if desired, generates a synthetic jet stream characterized by a series of successive vortices that can be used for effectively entraining adjacent fluid. The synthetic jet actuator can be used to bend, or vector, a jet stream from another jet actuator. Further, because the synthetic jet actuator exhibits zero net mass flux, the synthetic jet actuator can be used within a bounded volume. In structure, the synthetic jet actuator comprises a housing defining an internal chamber and having an orifice. A flexible metallized diaphragm forms a wall of the housing and can change the volume of the chamber when moved. An electrode is disposed adjacent to and spaced from the diaphragm, and an electrical bias is imposed between the metallized diaphragm and the electrode by a control system to force movement of the diaphragm. As the diaphragm moves, the volume in the internal chamber changes and vortices are ejected from the chamber through the orifice.

摘要： A device for use in combination with a fluid flow having a biologic component and subject to an adverse response to shear stress includes a surface in contact with the flow of the fluid. The surface has a longitudinal direction extending from a leading end toward a trailing end and aligned with a direction of the flow. The surface is susceptible to inducing boundary layer formation within the flow sufficient for a resulting shear stress to induce the response. The surface includes a surface feature sufficient to induce boundary layer tripping in the flow to retard growth of boundary layer formation along the length.
