Supersonic shear layers experience instabilities that generate significant adverse effects; in
complex configurations, these instabilities have global impacts as they foster compounding …

We investigate the perturbation dynamics in a supersonic shear layer using a combination of
large-eddy simulations (LES) and linear-operator-based input-output analysis. The flow …

For modern military aero-engine, the serpentine nozzle with aft deck is deployed to meet the
requirements of stealth and integrated design. Different from existing studies which …

A novel combination of physics-based and data-driven post-processing techniques is
proposed to extract acoustic-related shear-layer perturbation responses directly from spatio …

Large-Eddy Simulations are used to study different active and passive control of a high-
speed turbulent multi-stream shear flow. The primary goal is to mitigate the prominent tone …

We analyze a supersonic multi-stream rectangular jet flow using the linear-operator-based
input-output method. The primary objective is to unravel the fundamental dynamics of …

Since its inception in the 1930s, the evolution of the jet engine has largely been dictated by
the need to improve propulsion and fuel economy while reducing noise and environmental …
