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.

An apparatus for the separation or liquefaction of a gas at cryogenic temperatures which comprises an isolated chamber comprises at least one front distillation column operating at cryogenic temperatures and also a pipe for transferring fluid coming from or going to the column, the pipe having a diameter D comprising a bend for changing the direction of flow of the fluid, with profiled deflector vanes placed inside the bend, with their concavity towards the centre of the bend forming a plurality of ducts.

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.

Provided is an apparatus for removing thermal stratification generated by turbulent penetration by using a rotation of an inner ring and an outer ring. The apparatus for removing thermal stratification removes thermal stratification formed in a branch pipe branching from a main pipe through which a high-temperature fluid flows, the apparatus including: a hollow body portion coupled to the branch pipe; an inner ring being magnetic and arranged inside the body portion so that an inner circumferential surface thereof is in contact with a fluid; and an outer ring arranged outside the body portion to face the inner ring, the outer ring being magnetic of a polarity opposite to a polarity of the inner ring, wherein, when the outer ring is rotated, the inner ring rotates by a magnetic force.

Provided is an apparatus for removing thermal stratification generated by turbulent penetration by using a rotation of a pipe wall. The apparatus removes thermal stratification formed in a branch pipe branching from a main pipe through which a high-temperature fluid flows, the apparatus including: a connection body portion including a hollow first body and a hollow second body, the first body being coupled to one side of the branch pipe, and the second body being spaced apart from the first body and connected to other side of the branch pipe; and a hollow rotating part between the first body and the second body, the rotating part rotating around a center of the branch pipe.

One or more techniques and/or systems are disclosed for improving a fluid stream profile in the flow of fluid through a fire monitor system. An exemplary technique involves a flow elbow having a first rib, a second rid, and a gap between the first rib and the second rib. The gap can be configured to allow fluid to flow through the gap to reduce turbulence in the flow of fluid through the elbow.
