Aerodynamic Noise Control Study of Nozzles with Triangular Chevrons

Abstract:

This paper has a small part of notion of chevron and the process that helps reducing the noise pollution. Based on the gas dynamic and geometrical parameters of a single flow jet engine one does a model of CFD data processing. In this process one observes the influence of chevrons on acoustic wave intensity produced by the jet . One studies a series of tests on triangular chevrons: immersions, the influence of the number of chevrons in order to settle the influence of the geometrical parameters on the flow and on the jet acoustics. Finally one presents the contribution of chevrons in noise pollution reduction.
