Onset of visible capillary waves from high-frequency acoustic excitation
Shuai Zhang, Jeremy Orosco, James Friend
Remarkably, the interface of a fluid droplet will produce visible capillary waves when exposed to acoustic waves. For example, a small (L) sessile droplet will oscillat…
Identification of weakly- to strongly-turbulent three-wave processes in a micro-scale system
Jeremy Orosco, William Connacher, James Friend
We find capillary wave turbulence (WT) to span multiple dynamical regimes and geometries -- from weakly to strongly nonlinear WT (SWT) and from shallow to deep domains -- all withi…
On-chip unidirectional waveguiding for surface acoustic waves along a defect line in a triangular lattice
Yun Zhou, Naiqing Zhang, Dia'aaldin J. Bisharat +5
The latest advances in topological physics have yielded a rich toolset to design highly robust wave transfer systems, for overcoming issues like beam steering and lateral diffracti…
Onset of low-frequency capillary waves driven by high-frequency ultrasound
Shuai Zhang, Jeremy Orosco, James Friend
High frequency thickness mode ultrasound is an energy-efficient way to atomize high-viscosity fluid at high flow rate into fine aerosol mists of micron-sized droplet distributions.…
Modeling fast acoustic streaming: steady state and transient flow solutions
Jeremy Orosco, James Friend
We describe a novel mathematical method to supplant the classic approach and properly treat the spatiotemporal scale disparities present between the acoustics and remaining fluid d…
Unveiling the Burgers-Riccati physics of fast acoustic streaming
Jeremy Orosco, James Friend
Inaccurate slow streaming models of acoustically-induced fluid flow remain in use due to the lack of a generalized alternative. The Multiscale Articulated Differentials Method (MAD…
Extensional viscosity of copper nanowire suspensions in an aqueous polymer solution
Amarin G. McDonnell, Naveen N. Jason, Leslie Y. Yeo +3
Suspensions of copper nanowires are emerging as new electronic inks for next-generation flexible electronics. Using a novel surface acoustic wave driven extensional flow technique…
Fluid-Structure Interaction in Deformable Microchannels
Debadi Chakraborty, J. Ravi Prakash, Leslie Yeo +1
A microfluidic device is constructed from PDMS with a single channel having a short section that is a thin flexible membrane, in order to investigate the complex fluid-structure in…
