Experimental Study of Coaxial Jets Mixing Enhancement Using Synthetic Jets

Synthetic jets perpendicular to the mainstream have been used experimentally study coaxial mixing enhancement in this paper. The parameters of such as vorticity, streamwise velocity, radial Reynolds shear stress, and turbulence intensity are measured using particle image velocimetry (PIV) hot wire anemometers. distribution characteristics these with without synthetic were obtained. mechanism was summarized by analyzing experimental results, it also found that momentum coefficient most critical factor for enhancement. comparative experiments fully verified mechanism, showing an appropriate coefficient, significantly enhanced mixing.
