Linear and nonlinear mechanisms of sound radiation by instability waves in subsonic jets
Significance of output:
Jet noise is the largest single source of noise of an aircraft at take-off, but noise prediction relies heavily on empirical methods. New methods based on improved fundamental understanding of jet noise mechanisms potentially offers competitive advantage to companies like Rolls-Royce, who together with EPSRC (EP/E032028/1) supported a three-year project at the University of Southampton, one of the outcomes of which was this paper which provided evidence (supported by experiments) for a different mechanism of sound generation involving deterministic and easily computable instability waves.
