  • Publication number: 20150015607
    Abstract: To convey tactile sensations over an open space, a system may use a vortex generator to direct one or more vortices at an object in 3-D space. Once a vortex strikes an object—e.g., a user's hand—it applies a force. The vortex generator can control the frequency and intensity of the vortices in order to provide different tactile sensations that correspond to virtual objects or events in a visual presentation. The system may identify and track objects in the real-world environment, and based on information provided by a device displaying the visual presentation, transmit instructions to the vortex generator to discharge vortices that convey a tactile sensation corresponding to the virtual object or event in the visual presentation. By doing so, the vortices augment the real-world environment to immerse the user in the visual presentation.

  • Patent number: 8684040
    Abstract: Roughness is added to the surface of a bluff body in a relative motion with respect to a fluid. The amount, size, and distribution of roughness on the body surface is controlled passively or actively to modify the flow around the body and subsequently the Vortex Induced Forces and Motion (VIFM). The added roughness, when designed and implemented appropriately, affects in a predetermined way the boundary layer, the separation of the boundary layer, the level of turbulence, the wake, the drag and lift forces, and consequently the Vortex Induced Motion (VIM), and the fluid-structure interaction. The goal of surface roughness control is to decrease/suppress Vortex Induced Forces and Motion. Suppression is required when fluid-structure interaction becomes destructive as in VIM of flexible cylinders or rigid cylinders on elastic support, such as underwater pipelines, marine risers, tubes in heat exchangers, nuclear fuel rods, cooling towers, SPAR offshore platforms.

    Abstract: An active vortex control system (AVOCS) includes a set of primary injectors that inject gas into a cavity to generate a vortex in front of and possibly around components inside the cavity. The vortex interferes with an external flow field in an opening to the cavity to protect the components from the external environment. Sets of secondary injectors may inject gas at a reduced mass flow into the cavity to compensate for energy losses to maintain the coherence of the vortex. The AVOCS is well suited for use in windowless endo- and exo-atmospheric interceptors to protect the electro-optical imagers and optical components from Earth atmosphere.

  • Patent number: 8381770
    Abstract: A blowoff tank (B) for receiving blowdown, blowoff, and drain water from an HRSG (C) or other type of boiler, so as to lower the temperature of that water enough to enable it to be discharged into a sewer system, includes a generally cylindrical vessel (50) and inlet pipes (60) through which the blowdown, blowoff, and drain water is introduced into the vessel. Each pipe has a radial segment (62) that passes through the sidewall (52) of the vessel, a generally vertical segment (64) that extends upwardly within the vessel, and a tangential segment (68) that opens into the vessel. The radial segment contains a small drain aperture (74). The tank also has a cooling line (90) through which cooling water is introduced into the vessel to lower the temperature of the blowdown, blowoff, and drain water in the vessel and a drain line (86) that drains the mixture of cooling water and blowdown, blowoff, and drain water from the vessel, but never exceeds the elevation of the apertures in the inlet pipes.

  • Publication number: 20120292017
    Abstract: A vortex-controlled variable flow resistance device ideal for use in a backpressure tool for advancing drill string in extended reach downhole operations. The characteristics of the pressure waves generated by the device are controlled by the growth and decay of vortices in the vortex chamber(s) of a flow path. The flow path includes a switch, such as a bi-stable fluidic switch, for reversing the direction of the flow in the vortex chamber. The flow path may include multiple vortex chambers, and the device may include multiple flow paths. A hardened insert in the outlet of the vortex chamber resists erosion. This device generates backpressures of short duration and slower frequencies approaching the resonant frequency of the drill string, which maximizes axial motion in the drill sting and weight on the bit. Additionally, fluid pulses produced by the tool enhance debris removal ahead of the bit.
