APPARATUS AND METHOD FOR GENERATING SWIRLING FLOW

摘要

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.
