Re-examining the boundary conditions in modelling SAW-driven acoustofluidic streaming
Qinran Wei, Suyu Ding, Yang Zhao +4
Numerical simulations of surface acoustic wave (SAW)-induced acoustic streaming are highly sensitive to the choice of second-order boundary conditions. This study systematically co…

Time-Reversed Water Waves Generated from an Instantaneous Time Mirror
Danming Peng, Yiyang Fan, Ruochen Liu +2
An instantaneous time mirror (ITM) is an interesting approach to manipulate wave propagation from the time boundaries. In the time domain, the reversed wave is previously proven to…

Topological-charge dependence of radiation torque for an acoustic-vortex spanner
Yuzhi Li, Gepu Guo, Juan Tu +5
Based on the analyses of the wave front and the wave vector of an acoustic-vortex (AV) spanner generated by a circular array of point source, the principle of object rotation is in…
