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 …

Flows past cavities at high-speeds have become increasingly important in applications such
as flame-holding and propulsion unstart control. Recently maturated linear techniques have …

Synchronized time-resolved schlieren and far-field pressure measurements were used to
examine control of a supersonic multi-aperture rectangular single-expansion ramp nozzle …

Supersonic multistream engines with single-expansion ramp nozzles use splitter plates to
separate the core from bypass streams. The resulting shear-layer instability imposes …

applied to a modern adaptive engine design and its effectiveness compared to an unaltered …

Experiments are conducted on a supersonic Multi-Aperture Rectangular Single Expansion
Ramp Nozzle with both passive and active flow control techniques. The baseline flow is …

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 …
