Abstract
Flow field characteristics of a free circular swirling jet are investigated in the present study considering three different swirl numbers 0.38, 0.56 and 0.80. The experiment is carried out in an air jet facility for Reynolds numbers 16300, 34400 and 49200. Pressure probe method is used for 3-hole wedge shaped yaw meter to measure and calculate the data. Mean flow velocity along with centerline mean velocity decay are analyzed where swirl changes the instinctive properties of circular jet and demolishes the potential core. Swirl motion creates negative flow field which changes the static pressure and kinetic energy distribution enormously. As a result, flow diverges earlier, and surrounding air enters into the flow field more rapidly which enhances the mixing performance of the jet.
