Sound generation and upstream influence due to instability waves interacting with non-uniform mean flows
Published online by Cambridge University Press: 20 April 2006
Abstract
Recent experiments reveal that mean spreading rates of artificially excited shear layers undergo abrupt changes at certain discrete positions within the flow. This paper is concerned with the interaction between externally excited instability waves and these regions of relatively sudden change in mean flow. While the main emphasis is on the acoustic field produced by these interactions, the upstream influence at the nozzle lip is also considered.
