Acoustic investigation on nozzles with different types of six lobed chevrons
This paper deals with a few aspects of the 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 a model of CFD data processing is made. In this process the influence of chevrons on acoustic wave int...

| description | This paper deals with a few aspects of the 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 a model of CFD data processing is made. In this process the influence of chevrons on acoustic wave intensity produced by the jet can be observed. A series of tests on six lobed triangular chevrons are discussed in order to settle the influence of the geometrical parameters on the flow and on the jet acoustics. Finally the paper presents the contribution of chevrons in noise pollution reduction. |
