The fluidic wallpaper is a novel concept to reduce lowfrequency broadband noise, operating
entirely in the fluid domain without any moving parts or electrical wiring. Pressure …

Experimentally, we demonstrate the feasability of a device build from the association of two
kinds of actuators, with specific controllers, to actively control the perturbations generated by …

A model problem comprising two subsytems (acoustic and hydrodynamic), both admitting
unsteady flows, has been studied using numerical simulations. Simulations capture all key …

this work is to develop a high-fidelity simulation model for active jet noise control predictions …

Actuator and sensor placement for active control of high-Reynolds number flows is largely
based on experience and trial-and-error because of the system's large dimensionality and …

An experimental investigation was performed in an anechoic wind tunnel involving acoustic
measurements, hot-wire anemometry and surface flow visualisation techniques to …

The current work is an experimental investigation on the use of open-loop flow control
techniques to reduce trailing edge noise of a flat plate. An array of inclined transverse jet …

The research presented in this paper has been directed to study the effects of mass injection
into the flow upstream of a cavity to actively control the development of upstream boundary …

A Large-Scale Simulations (LSS) code is developed herein to model and optimize the
performance of a synthetic jet device when the forcing amplitude is an acoustic wave …
