Turbulence characteristics of truncated chevron nozzle

This paper discusses the Computational Fluid Dynamic study on the turbulence characteristics of chevron nozzle with truncated petals. To study the turbulence characteristics of the jet, truncated chevron nozzle with 6 petals and plain chevron nozzle with six petals is chosen. For the exit Mach number of 1.0, the turbulence kinetic energy that varies along the axis of the jet is measured for the truncated chevron nozzle and it compared with the plain chevron nozzle. The turbulence kinetic energy for the truncated chevron nozzle is more at the near field of the jet when compared to the plain chevron nozzle. The increase in the turbulence is due to the vortices of mixed sizes initiated from the edges of the petals of truncated chevron nozzle. The turbulence kinetic energy at various locations on the axis of the jet is also studied for the jet exit Mach number of 1.0.
