The oscillating and vibrating cylinder: a benchmark to study low Mach number aeroacoustics
Étienne Spieser, Siyang Zhong, Xin Zhang
Hydrodynamic and acoustic scales separate as the Mach number decreases, making the modelling of aeroacoustic phenomena singular in this flow regime. The benchmark of the flow devel…
Acoustic Invisibility in Turbulent Fluids
Xun Huang, Siyang Zhong
Acoustic invisibility of a cloaking system in turbulent uids has been poorly understood. Here we show that evident scattering would appear in turbulent wakes owing to the submergen…
Compressive sensing based beamforming for noisy measurements
Siyang Zhong, Xun Huang
Compressive sensing is the newly emerging method in information technology that could impact array beamforming and the associated engineering applications. However, practical measu…
Circular Sound Wave Scattering Derivation for Acoustic Cloak Detection
Siyang Zhong, Xun Huang
In this Letter we develop analytical formulations to describe sound scattering in lossless medium due to 2D circular wave incident on an acoustic cloak. A perfect acoustic cloak is…
