Material flow amplifiers 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).

Such cyclonic flow-inducing 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 adverse considerations such as slugging.

Methods and systems are provided for an exhaust gas mixer. In one example, a system may comprise an outer annular portion exterior to an exhaust pipe and an inner annular portion interior to the exhaust pipe, where the outer annular portion comprises a spiral fin extending around the exhaust pipe in a downstream direction.

A fluid mixing device includes a hollow tubular main body (41) to mix an exhaust gas (G4) and a warming gas (G5) within it, a first inflow port (43) provided in an upstream end portion of the main body (41) and through which the exhaust gas (G4) flows, a mixing promotion body (38) of a tubular shape disposed inside the main body (41) and having a longitudinal axis (C1) extending in a direction conforming to a direction of flow of the exhaust gas (G4), and a second inflow port (45) provided in a peripheral wall of the main body (41) and through which the warming gas (G5) flows towards an outer peripheral wall of the mixing promotion body (38). The exhaust gas (G4) flows outside and inside the mixing promotion body (38).

This invention is a low pressure, steady volume supply static mixer manifold for a high pressure pump. The design comprises an internal diffuser cylindrical tube inside an external rectangular tube in which static mixing occurs. Capped at one end, the internal diffuser pipe, with flow coming from the opposite side, allows for one flow direction diffused into the outer rectangular tube that then allows for constant bidirectional flow at a constant pressure throughout. The flow of slurry components between the cylindrical tube and the rectangular tube supports static mixing in part by creating alternating flow pressures between mixing ports (allowing flow of slurry components from the cylindrical tube) and the exit ports based on the different geometries of the cylindrical tube and rectangular tube. The combination of flow and pressure exiting the cylindrical tube through the mixing ports, at an angle to the bottom corners of the outer rectangular tube, creates a natural agitation of the slurry components. The cutouts in the inner tube are sized and spaced for providing the proper flow, mix, and pressure to each exit port.

Methods and systems are provided for an exhaust gas mixer. The system comprises a urea injector injecting urea into a perforated tube having a U-shaped bend housed by the exhaust gas mixing chamber. The perforated tube further has an outlet fluidly coupled with an exhaust passage, with an SCR catalyst positioned downstream of the exhaust passage.
