Three-dimensional numerical modeling of surface acoustic wave devices: Acoustophoresis of micro- and nanoparticles including streaming
Nils R. Skov, Prateek Sehgal, Brian J. Kirby +1
Surface acoustic wave (SAW) devices form an important class of acoustofluidic devices, in which the acoustic waves are generated and propagate along the surface of a piezoelectric…

Using Acoustic Perturbations to Dynamically Tune Shear Thickening in Colloidal Suspensions
Prateek Sehgal, Meera Ramaswamy, Itai Cohen +1
Colloidal suspensions in industrial processes often exhibit shear thickening that is difficult to control actively. Here, we use piezoelectric transducers to apply acoustic perturb…
