twin-jet configuration often seen in military aircraft, the jets can become coupled, resulting in …

Flow control is typically used to manipulate a flow's natural behavior to alter its effects on a
vehicle or system. When active flow control (AFC) is used in aerospace applications, the …

A pressure distribution inside a two-dimensional rectangular cavity with a ratio L/D= 5.0 of
the cavity length L to the depth D over a supersonic flow was obtained using an improved …

A control method is developed to suppress pressure oscillations induced by supersonic
cavity flow using high-speed upstream injection. The injection is generated with a large …

Numerical aeroacoustic analysis was conducted on an M219 cavity geometry, incorporating
signature suppression features and leading-edge fluidic spoilers. The numerical model was …

Written by a leading expert in the field, this book presents a novel method for controlling high-
speed flows past aerodynamic shapes using energy deposition via direct current (DC), laser …

AERODYNAMIC control is one of the major challenges in supersonic/hypersonic vehicle
design. Effective manipulation of the flowfield can lead to a number of significant benefits to …
