An Experimental Study on Comparison of Non-circular Co-flow Jet with Co-axial Jets and Computational Verification

摘要

The present study addressed the experimental investigation followed by computational validation of incompressible single and co-axial jet. The characteristics of non-circular co-flow jets have been analysed for different types of orifices, i.e., circular, hexagon and crusi-form. The flow field's characteristics like centerline velocity, spreading rate, velocity along radial direction and potential core length have been determined by using Pitot tube. Using FLUENT the numerical simulation has been carried out and compared with experimental results. Significant similarities have been obtained in experimental and computational data. Though the axial velocity magnitude of single jet was less than the coaxial jet, but the jet half width of single circular jet was found higher than the jet half width of coaxial jets.
