Abstract The paper deals with the mixing enhancement of the flow through the Nozzle exhaust which is done by attaching Injection tubes along the Chevron tip. Numerical simulations are carried out on Chevron Nozzle to assess the importance of Injection tubes of various shapes. Air injection is made from the tubes that are placed tangent to the nozzle outer surface with an injection pressure of 10 psi and the chosen nozzle exit Mach numbers of 0.4 and 0.8 respectively. The result concludes showing subsequent changes in the jet plume’s turbulence and vortices formation in the region immediate downstream of the nozzle exit. We then compare the results of Chevron nozzle with and without injection tubes and also between the injection tubes of various shapes using ANSYS CFX software.
