Abstract
A static mixer for mixing a mass fluid flow includes an elongate body including an open proximal end, an open distal end and an inner wall. At least a portion of the inner wall includes a plurality of undercuts formed therein to define a convoluted conduit. The conduit extends along a central axis between the proximal end and the distal end. A portion of the undercuts defines a center-to-perimeter flow portion within the conduit. A portion of the undercuts defines a perimeter-to-center flow portion within the conduit.
Claims25
A static mixer for mixing a flow of at least one fluid, the static mixer comprising:
- an elongate body having an open proximal end, an open distal end, and an inner wall, at least a portion of the inner wall having a groove and a plurality of undercuts formed therein to define at least one convoluted conduit, the conduit extending along a central axis between the proximal end and the distal end, wherein a portion of the undercuts defines a center-to-perimeter flow portion within the conduit, and a portion of the undercuts defines a perimeter-to-center flow portion within the conduit,
- wherein the groove is defined at least in part by a first undercut and a second undercut of the plurality of undercuts, the first undercut and the second undercut being opposite one another in the inner wall.
A static mixer for mixing a flow of at least one fluid, the static mixer comprising:
- an elongate body extending along a central axis and including an open proximal end, an open distal end, and an inner wall, the inner wall including a groove and a plurality of undercuts formed integrally therein to define a single flow path,
- wherein the groove is defined, at least in part, by a first undercut of the plurality of undercuts and a second undercut of the plurality of undercuts,
- wherein the first undercut is defined by a first ridge of the inner wall, a proximate portion of the first ridge positioned adjacent a first face of the inner wall and a distal portion of the first ridge positioned adjacent a second face of the inner wall,
- wherein the second undercut is defined by a second ridge of the inner wall, a proximate portion of the second ridge positioned adjacent the second face of the inner wall and a distal portion of the second ridge positioned adjacent the first face of the inner wall,
- wherein at least a portion of the flow path extends coaxially along the central axis, at least a portion of the flow path extends radially away from the central axis, and at least a portion of the flow path extends radially towards the central axis, and
- wherein the first undercut and the second undercut are opposite one another in the inner wall.
A static mixer for mixing a flow of at least first and second fluids, the static mixer comprising:
- an elongate member having an open proximal end defining an inlet portion, an open distal end defining an outlet portion, and a mixing portion between the inlet portion and outlet portion, the mixing portion including a first convoluted conduit extending along a central axis from the inlet portion towards the distal end, and a second convoluted conduit extending along the central axis from the inlet portion towards the distal end, the first and second conduits being fluidly connected by at least one third conduit extending between the first and second conduits in a direction transverse to the central axis.
