An apparatus for dispersing particles in a fluid, comprising: a flow divider for receiving the fluid and for separating the fluid into a first fluid stream and a second fluid stream; first and second fluid branches for receiving the fluid streams; a branch joining section for receiving the fluid streams, the branch joining section having a collision zone for allowing the first and second fluid streams to collide; a first nozzle that is arranged in the first fluid branch; and a second nozzle is arranged in the second fluid branch, the first nozzle comprising an orifice that is followed by a fluid diverging section.

A valvular conduit, preferably a Tesla valvular conduit, in which a plug member is coaxially received within a bore in a sleeve member and in which passageways are defined between the plug member and the sleeve member within interior walls configured to permit mixing of fluid flowing through the passageways in at least one direction, preferably, the relatively free passage of fluid through the passageways upstream but increased the resistance to downstream flow of the fluid through each passageway.

Rotary in-line pumps as disclosed herein 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.

The device is a gas-liquid mixing device having a venturi structure in which a throat portion and an enlarged diameter portion are provided in a main passage through which a liquid passes, the gas-liquid mixing device including a collision chamber provided on an outer periphery of the enlarged diameter portion, and a stirring chamber provided downstream of the enlarged diameter portion. A collision flow path communicating with the collision chamber and causing a gas-liquid to collide with an outer peripheral wall, a straight flow path through which the gas-liquid passing through a central portion of the enlarged diameter portion travels straight, and an outer ring flow path through which the gas-liquid flows from the collision chamber to the stirring chamber are formed downstream of the enlarged diameter portion. The gas-liquids from the outer ring flow path and the straight flow path are stirred in the stirring chamber.

A method for controlling fluid ratio accuracy during a dual flow injection with a powered injection system is described. The method includes predicting a first capacitance volume of a first syringe comprising a first medical fluid and a second capacitance volume of a second syringe comprising a second medical fluid with a first capacitance correction factor and a second capacitance correction factor, respectively, selecting a ratio of the first medical fluid and the second medical fluid to be administered to a patient in the dual flow injection, determining a relative acceleration ratio of a first piston of the first syringe and a second piston of a second syringe based on the predicted first capacitance volume and the predicted second capacitance volume, wherein the relative acceleration ratio is selected to maintain the selected ratio of the first medical fluid and the second medical fluid during the dual flow injection, and injecting a mixture of a first medical fluid and a second medical fluid having the selected ratio with the powered injection system.
