Numerical analysis of subsonic jets with and without tabs (vortex generators with exit area blockage of 4.84%) has been done in the present research paper. Two tabs has been fixed at nozzle exit diametrically opposite. ANSYS CFX software was used for analysis purpose and to understand the flow characteristics at four different Mach numbers 0.4, 0.6, 0.8 and 1.0. The main objective of the present study is to analyze the effect of innovative vortex generators in the form of solid tabs with triangular fins on either side offset to each other on the performance characteristics. Due to counter rotating streamwise vortices, there is large engulfment of masses from ambient air into the core jet, resulting in the reduction of potential core length.
