Chevrons,Nozzles, Noise,Turbulence,


With the increase in advancements in the aerospace industry, the introduction of the concept of the chevron to reduce noise and turbulence has been effective to a certain extent. In the present context, a baseline axisymmetric separate-flow nozzle with standard dimensions is taken into consideration. Then the chevron nozzle represents the conventional chevron nozzle in use today. Noise emission and its intensity have been a major concern for the past few decades. This paper mainly deals with the velocity magnitude and acoustic power level of the four types of nozzles which includes the combination of two nozzles accounting the baseline model and its modification with a set of chevrons. Based on the two results the unprejudiced one is ideal for the airplane.
