摘要

The Flow measurements were made in the circular jets using two tabs at nozzle exit, placed diametrically opposite locations. The total pressure was measured along the jet axis (X-Axis) and normal to the jet axis (Y-Axis) at Mach number 0.2. Also, total pressure was measured for free jet to compare the results. The effectiveness of circular solid tabs and circular tabs with hole to enhance the mixing of axi-symmetric subsonic jets has been presented in this paper. It is found that both the circular solid tabs and circular tabs with hole significantly enhance the mixing of jets. The potential core length were reduced by 37.5% and 62.5% for jet of circular tab with hole and solid tabbed jet compared to free jet respectively.
