SOLUTIONS TO THE NAVIER-STOKES EQUATIONS IN A NON-INERTIAL REFERENCE FRAME

open access: yes, 2003
A general rotating frame formulation of the Navier-Stokes equations has been added to the incompressible and arbitrary Mach number versions of UNCLE. While eliminating the need for moving grids, this formulation also reduces the error caused by linear ...

Intelligent Acousto‐Electrical Metamaterials (IAM) for Sound Source Detection

open access: yesAdvanced Materials, EarlyView.
Our proposed metamaterial concept enables sound source detection using a single material, in contrast to conventional arrays that require dozens or even hundreds of transducers. We show that the coupled acoustic–vibrational–electrical responses in piezoelectric metamaterials give rise to topology‐governed charge transport, producing distinct voltage ...
