Abstract: A fluid flow conditioning apparatus having a plurality of flexible microstructures that reduce flow losses within a conduit. The plurality of microstructures is affixed to an insertion plate-type flow conditioner. One or more ends of the microstructures are secured to internal walls of the flow conditioner. The microstructures are configured to move and flex in response to static and dynamic pressure exerted onto the microstructures by the fluid flow. The microstructures may be made of a hyperelastic material configured to undergo an elastic deformation due to the dynamic pressure of the fluid flow.

Abstract: A conduit system for transporting gas from a gas containing chamber for processing a substrate from which semiconductor devices are formed includes a liner with a spiral vent. The conduit system utilizes a curtain of gas to prevent or reduce deposition of material onto an inner surface of the conduit transporting the gas from the gas containing chamber.

Abstract: Systems and methods are described herein to implement transverse momentum injection at low frequencies to directly modify large-scale eddies in a turbulent boundary layer on a surface of an object. A set of transverse momentum injection actuators may be positioned on the surface of the object to affect large-scale eddies in the turbulent boundary layer. The system may include a controller to selectively actuate the transverse momentum injection actuators with an actuation pattern to affect the large-scale eddies to modify the drag of the fluid flow on the surface. In various embodiments, the transverse momentum injection actuators may be operated at frequencies less than 10,000 Hertz.

Abstract: Material flow modifiers as disclosed herein overcome drawbacks associated with known adverse flow conditions (e.g., surface erosion, head losses, particulate drop-out, and the like) that arise from flow of certain types of materials (e.g., fluids, slurries, particulates, flowable aggregate, and the like) through a material flow conduit. Such material flow modifiers provide for flow of flowable material within a flow passage of a material flow conduit (e.g., a portion of a pipeline, tubing or the like) to have a rotational flow profile. Advantageously, the rotational flow profile centralizes flow toward the central portion of the flow passage, thereby reducing magnitude of laminar flow to overcome the aforementioned adverse flow conditions.

Abstract: Disclosed fluid flow modifying devices are useful with flexible fluid flow conduits. Such devices are adapted for mitigating adverse flow considerations arising from one or more bends in flexible fluid flow conduits. These adverse flow considerations are generally characterized as enhanced laminar flow and associated increased backpressure arising from reduced flow velocity caused by the one or more bends. Beneficially, disclosed fluid flow modifying devices cause flow of flowable material (e.g., a liquid) within a flow passage of a fluid flow conduit to have a rotational flow profile. Such a rotational flow profile advantageously reduces frictional losses associated with laminar flow and with directional change of fluid flow.

Abstract: The systems and methods provided herein are directed to a stationary device for simulating the periodic unsteadiness typically produced by turbines in an air stream. A streamlined body includes a line of jets along its leading edge that pulses air at an angle against the air stream, and a separate line of jets along its trailing edge to expel a sustained air flow in the same direction as the air stream.

Abstract: A plurality of resistance-imparting portions (34A to 34E) are disposed adjacent to each other. A first contraction flow portion forming one of the resistance-imparting portions (34A to 34E) adjacent to each other is in communication with an enlarged diameter portion forming another resistance-imparting portion. First contraction flow portions (32AH to 32DH) forming the resistance-imparting portions (34A to 34E) adjacent to each other are disposed at different positions in a direction in which an outer frame member (31) extends.
