The present study is focused on the development of an empirical low-order dynamical
system (LODS) of a Mach 0.6 high-speed axisymmetric jet to be ultimately used for closed …

Efforts to reduce the noise from turbulent jets at fixed flow conditions, with aircraft noise as
the principal technological motivation, have generally involved some degree of parametric …

This body of work seeks to explore novel methods for reducing aeroacoustically generated
noise through the introduction of localized perturbations around the periphery of a Mach 0.6 …

In the last few years, flow control has become increasingly important for the aeronautical
field, since it is seen as a promising tool to design safer and more efficient aircraft. In this …

In flow acoustical problem sets, there is typically a large disparity of scales between
hydrodynamical and acoustical phenomena both in amplitude and spatial extent. This …

The emitted noise from round jets is reduced using linear feedback controllers designed
using structural sensitivity analysis. Linear global modes inform the selection and placement …

Flow-induced noise generation by external flow devices operating at low to intermediate
Reynolds number is an overriding concern associated with their design and operations …

Our recent numerical and experimental efforts are reviewed examining flow-acoustic
resonant interactions in transitional airfoil boundary layers and means of control of the …
