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.

An outer edge portion of each of the helix vanes is attached to the outer shell and an inner edge portion of each of the helix vanes is located within a central passage of the central tube. In this manner, a first portion of each of the helix vanes extends between the outer shell and the central tube and a second portion of each of the helix vanes is located within the central passage of the central tube.

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: Material flow amplifiers as disclosed herein overcome drawbacks associated with known adverse flow conditions (e.g., surface erosion and head losses) 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 amplifiers 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 cyclonic flow (i.e., vortex or swirling) profile. Advantageously, the cyclonic flow profile centralizes flow toward the central portion of the flow passage, thereby reducing magnitude of laminar flow. Such cyclonic flow profile provides a variety of other advantages as compared to a parabolic flow profile (e.g., increased flow rate, reduce inner pipeline wear, more uniform inner pipe wear, reduction in energy consumption, reduced or eliminated slugging and the like).

Abstract: Material flow amplifiers comprise at least one helix vane within a vortex chamber of an amplifier body and at least a portion of an outer edge portion of the at least one helix vane is attached to an interior surface of the amplifier body. A centralizer tube is centrally located within the amplifier body and has at least a portion of an inner edge portion of the at least one helix vane is attached to an exterior surface thereof. Such material flow amplifiers provide for flow of flowable material within a flow passage of a material flow conduit to have a cyclonic flow (i.e., vortex or swirling) profile. Advantageously, the cyclonic flow profile centralizes flow toward the central portion of the flow passage, thereby reducing laminar flow to provide for increased flow rate in addition to reducing inner pipeline wear and energy consumption.

Abstract: Disclosed material flow amplifiers have opposing amplifier bodies each with a profile that jointly defines an amplifier body (i.e., “clamshell configuration”). The amplifier body has a flow expander section and a vortex inducer section. A vortex chamber insert is within at least an interior space of the vortex inducer section. Such material flow amplifiers 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 cyclonic flow (i.e., vortex or swirling) profile. Advantageously, the cyclonic flow profile centralizes flow toward the central portion of the flow passage, thereby reducing laminar flow.

Abstract: Fluid flow enhancing devices disclosed herein are adapted to enhance flow of fluid through subsurface watershed conduits, for example, culverts, drainpipe and the like. Such fluid flow enhancing devices advantageously enhance watershed runoff functionality in subsurface watershed conduits by altering watershed flow from a parabolic flow pattern to a rotational flow pattern while still accommodating fish passage requirements. This change in flow pattern beneficially provides turbulence that disrupts and flushes debris out of the subsurface watershed conduits. This disruption and flushing establishes a passive cleaning functionality within the subsurface watershed conduits that serves to clean the subsurface watershed conduits after suitable upstream water delivery event (e.g., heavy rain, controlled water release, etc.).
