A recently granted patent (Publication Number: US11919028B2) discloses a method for atomizing a fluid using a unique configuration of inner and outer members. The method involves coupling an inner member with an axis to a first outer member that defines a second-fluid supply conduit. Additionally, the inner member is coupled to a second outer member, creating a second-fluid flowpath that includes a tangential conduit spiraling along the axis, an annulus, and a discharge plenum. The fluid is directed through this flowpath from the second-fluid supply conduit, and further steps involve mixing the fluid with another fluid, directing it through swirl slots, and controlling the dimensions of entry and exit plenums for efficient atomization.

Furthermore, the patent describes variations in the method, such as the inclusion of swirl slots between the exit plenum and annulus, the formation of the outer members as a unitary member, and the positioning of a first-fluid conduit radially outward of the second outer member. The method also details the flow of fluid through the tangential conduit, the circumferential displacement of the terminal end from the supply conduit, and the use of swirl slots with a specific orientation. Overall, the patent presents a comprehensive approach to atomizing fluids by optimizing the flowpath design and incorporating various elements to enhance atomization efficiency and control.
