Abstract

A fluid mixer apparatus can include an annular ring defining a fluid flow path configured for a first fluid through the annular ring. The annular ring can include one or more fluid inlets circumferentially disposed on an exterior surface of the annular ring, the one or more fluid inlets configured to receive a second fluid different than the first fluid. The fluid mixer apparatus can include a central hub and a plurality of helical airfoils positioned inside the annular ring and connected to both of the annular ring and the central hub. In some examples, each helical airfoil of the plurality of helical airfoils can include: a plurality of perforations in fluid communication with the one or more fluid inlets to introduce the first fluid into the second fluid; and an airfoil surface perturbation positioned adjacent to or rearward of the plurality of perforations.

IPC Classes  ?

• B01F 25/314 - Injector mixers in conduits or tubes through which the main component flows wherein additional components are introduced at the circumference of the conduit
• B01F 25/00 - Flow mixersMixers for falling materials, e.g. solid particles
• B01F 25/4314 - Straight mixing tubes with baffles or obstructions that do not cause substantial pressure dropBaffles therefor with helical baffles

Abstract

A fluid mixer apparatus can include: a single-piece housing defining a fluid flow path configured for a first fluid through the single-piece housing; a fluid inlet defining on an exterior surface of the single-piece housing, the fluid inlet configured to receive a second fluid different from the first fluid; an inner chamber circumferentially defined inside the single-piece housing, the inner chamber configured to receive the second fluid from the first inlet; a central hub; and a plurality of helical airfoils coupled to an interior surface of the single-piece housing and the central hub, the plurality of helical airfoils being in fluid communication with the inner chamber. Each helical airfoil can include: a plurality of perforations in fluid communication with the inner chamber to introduce the second fluid into the first fluid; and an airfoil surface perturbation positioned adjacent to or rearward of the plurality of perforations.
