Interaction chamber with flow inlet optimization

摘要

A mixing assembly includes an inlet, an outlet and a mixing chamber, the inlet is fluidly connected to the outlet through a plurality of micro fluid flow paths in a direction perpendicular from the inlet. The micro fluid flow paths fluidly connect to the perpendicular inlet via a curved transition portion. The curved transition portion provides a more efficient flow path for the fluid to travel from the inlet to the micro fluid flow paths to the mixing chamber. By transitioning the direction change, flow resistance is decreased, and the fluid flow rate and shear rate is increased. Increased fluid flow rate and shear rate helps to increase consistency and quality of mixing, and to reduce particle size of the fluid in the mixing chamber.

1. A mixing chamber assembly, comprising:
(a) a first mixing chamber element having a first surface and an inlet port; (b) a second mixing chamber element having a second surface and an outlet port, the second surface sealingly engaged with the first surface of the first mixing chamber element; (c) a micro fluid path defined between the first and second mixing chamber elements and having an input end at the inlet port; (d) a flared transitional portion defined at the input end of the micro fluid path and providing fluid communication between the inlet port and the micro fluid path; and (e) a mixing chamber defined by the first and second mixing chamber elements and in fluid communication with the micro fluid path and the outlet port;wherein the first and second mixing chamber elements are configured to accept a high pressure fluid flow along a flow path, the flow path:
(1) extending in a first direction toward the first and second surfaces through the inlet port,(2) extending through the flared transitional portion from the inlet port to the micro fluid path;(3) extending along the micro fluid path in a second direction from the flared transitional portion to the mixing chamber; and(4) extending from the mixing chamber through the outlet port in a third direction away from the first and second surfaces.
