Confined Mixing of Multiple Transverse Jets

Abstract

. Results for two jets indicate monotonically decreasing unmixednessfor the range of conditions tested, with no local optimum apparent. Data for three jets indicate a local optimum at ( ⁄ ) and relatively flat range of mixing performance in the range of ( ⁄ ). Six jets indicate a minimum unmixedness near ( ⁄ ) , but exhibited poorer mixing performance than all other configurations at the highest values of ( ⁄ ) tested. The most optimum configuration tested was six jets at ( ⁄ ) , resulting in an unmixedness of 0.0192. This value was 76% lower than the next lowest configuration (three jets) at the same ( ⁄ ) Total momentum was found to collapse the data well, as configurations more closely matched a historical correlation for second moment of a single confined jet more closely.
