This study aims to investigate the effect of front and aft wall modifications and their
combinations on the sound pressure level response of the deep configuration of the M219 …

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

Turbulent flows at a free stream Mach number of 1.19 over an open cavity with L/D ratio of
5.0 are numerically investigated using improved delayed detached-eddy simulation based …

During ascent of launcher, the unsteady aerodynamic loads associated with transonic buffet
flow have become of considerable concern. To study the unsteady dynamics of buffet flow …

The internal weapon bay is widely used in modern aircraft; however, because the unsteady
flows of the cavity would cause dangerous store separation and intense aerodynamic noise …

Cavity-induced transition (CIT) in a hypersonic boundary layer was simulated by employing
direct numerical simulation (DNS). The upwind Roe scheme was discretized by high-order …

Numerical investigations of the leading-edge sawtooth spoiler and slanted aft wall were
performed to explore the mechanisms of the suppression of pressure fluctuations in an open …

The transition has an important effect on the aerodynamic performance and energy
consumption of the wind turbine. When the angle of attack is sufficiently large, separation …

In this paper, active control of flow-induced cavity resonance noise is addressed. A hybrid
numerical method is presented to predict the resonance frequency and, instead of traditional …

The delayed detached eddy simulation (DDES) model has achieved great success in
simulations of massive separations, but has been found to significantly delay the Kelvin …
