In this manuscript, compare jet characteristics of a base nozzle, jet characteristics of a nozzle of same dimension with different chevron structures present with a rectangular slot of dimension 3:2 ratio and a depth of 1mm, jet characteristics of a nozzle with chevron structure present with a triangular slot of dimension 4mm radius and a depth of lmm. To analysis the Mach number decay and turbulent characteristics along the jet flow to analysis the decay of noise in the near nozzle region. The jet characteristics for various Mach number and turbulent were analysed. The aeroacoustics phenomenon of jet noise, which is strongly related to turbulence dynamics in the jet shear layers downstream of the jet potential core, remains a large component of the overall noise produced by high-speed aircraft.Chevrons, sawtooth design on the boundary layer of exit nozzles, will be incorporated on aero kits.Within these initial periods, the chevron with more energetic penetrate was researched with an emphasis on combining optimization in nozzles.Technical chevron shapes on the nozzle outer radius improve jet phase mixing and, as a result, minimize far-field noise.A convergent nozzle is considered with four chevron structures at the exit. The flow characteristics are analysis for free jet, chevron nozzle, rectangular slotted chevron nozzle and triangular slotted chevron nozzle for high speed jet. The flow characteristics are concluded by the simulation software on comparing the flow characteristics, the mixing enhancement of various nozzles are performed. The comparison reveals that the chevron nozzle enhances the mixing of flow, which results in suppression of turbulent kinetic energy at large eddies frequency zone. © 2023 Elsevier B.V., All rights reserved.
