Effect of Annular Jet on an Existing Jet

Jets have a wide range of applications in several fields. However studying the jet characteristics by introducing a flow field of different velocity annularly to the existing jet is a classic example considered for various applications. When a jet is surrounded by a flow field of different velocity then it is termed as co-flowing jet or co-annular jets. Co-annular jets have a wide range of applications in mixing and noise reduction characteristics. A comparison is drawn between a convergent nozzle and a A co-annular convergent inner nozzle having inlet diameter 22mm, exit diameter 5mm is surrounded by an annular convergent circular nozzle with inlet diameter 42mm, exit diameter 23mm is used for studying the results. Experiments are conducted for without co-flow and with co-flow at a velocity of 50 m/s in the present investigation. It is incurred that co-flow jets have a great impact in modifying the jet and enhances better mixing.
