  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 submergence of a classical cloaking device. The inherent
mechanism is explained using our theoretical model, which eventually inspires
us to develop an optimized cloaking approach. Both the near- and far-field
scatted fields are examined using high order computational acoustic methods.
The remarkably low scattering demonstrates the effectiveness of the proposed
acoustic cloaking approach for turbulent uid cases.
