Acoustic characteristics of the flow over different shapes of nozzle chevrons
Journal Title: INCAS BULLETIN - Year 2013, Vol 5, Issue 3
Abstract
The objective of this paper is to present a comparison between different types of chevrons and their influence on the acoustic power level radiated by the flow over them. The comparison was performed using a two-dimensional simulation of the flow over four different shapes of chevrons resulting propagation of the acoustic waves for each shape. Acoustic characteristics were revealed studying the main flow parameters (pressure, velocity, kinetic energy) in order to be able to discover the most efficient shape of chevron regarding the acoustic power level emitted.
