摘要： 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).

摘要： Rotary in-line pumps overcome drawbacks associated with known adverse flow conditions that arise from flow of certain types of materials through a material flow conduit. Such rotary in-line pumps 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 such as, for example, increased flow rate, reduce inner pipeline wear, more uniform inner pipe wear, reduction in energy consumption, reduced or eliminated slugging and the like.

摘要： 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.). In doing so, these fluid flow enhancing devices overcome one or more shortcomings associated with subsurface watershed conduits in a manner that overcomes drawbacks associated with conventional design and in-use considerations for such subsurface watershed conduits.

摘要： 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.
