There is a need of increase in efficiency and reduction of sound in jet engine where the researchers found that if mixing enhancement is made possible at the area prior to the primary zone of the combustion chamber the efficiency could be increased. As the free jet out of the nozzle taken the time to decay, there is a possibility for the fuel to exit at high speed in an unburnt state which primarily tends to reduce the efficiency of the jet engine. To overcome this problem, a square shaped fin tabs were designed and fabricated and the same was fixed diametrically opposite to the nozzle exit to create formation of vortices, thus the decay is made to be smaller and mixing of air and fuel will be enhanced. The experimental study was made along with data acquisition system to witness the effect of Mach number variation on and pressure ratio with respect to X/D as well as Mach number ratio by having a supply of air at M = 0.4, 0.6, and 0.8 in both the cases.
