This special edition of the International Journal of Aeroacoustics contains 12 papers originally presented at the Noise & Turbulence: Perspectives Past & Present Symposium (2009: University of Southampton). The symposium was held in honor of Professor Geoffrey M. Lilley, a multi-faceted educator and researcher. Selected are the papers specific to aeroacoustics covering aerodynamic noise theory, airframe noise, flow control, and experimental jet noise studies. Topics include a brief biography of Lilley, the relation between the generalized acoustic analogy and Lilley's contributions to aeronautics, solving the Lilley equation with quadrupole and dipole jet noise sources, hot jets and sources of jet noise, wave packet modules for large-scale mixing noise, and plasma actuators for noise control.
Editor Dr. Philip J. Morris (Aerospace Engineering, Penn State University) and 22 prominent co-authors contributed.
