Abstract:
An apparatus and method for generating a swirl is disclosed that is used to induce an axi-symmetric swirling flow to an incoming flow. The disclosed subject matter induces a uniform and axi-symmetric swirl, circumferentially around a discharge location, thus imparting a more accurate, repeatable, continuous, and controllable swirl and mixing condition of interest. Moreover, the disclosed subject matter performs the swirl injection at a lower pressure drop in comparison to a more traditional methods and devices.

Claim (Index 19):
A swirl generator comprising:\n a center chamber coupled to a upstream nozzle and a downstream nozzle, wherein the upstream nozzle and the center chamber define a main flow path, and wherein the upstream nozzle is attached to a first side of the center chamber and configured to introduce a main flow to the center chamber and the downstream pipe is attached a second side of the center chamber and configured to receive a uniform axisymmetric flow from the center chamber; a plenum defined by an inner wall of the center chamber and an exterior surface of the upstream nozzle; an injector coupled to the center chamber, wherein the injector is substantially perpendicular to the center chamber, the injector including a tangential injection port; and a tangential injection port coupled to and in fluid communication with the plenum, wherein the tangential injection port is configured to convey a second flow into the plenum, an angled slot positioned between the tangential injection port and the center chamber, wherein the slot defines the fluid pathway between the plenum and the main flow path and wherein the angled slot is formed by an angled exterior wall of the upstream nozzle and an angled interior wall of the downstream nozzle.
