Acoustofluidic Suppression of Rayleigh Taylor Instability and Fluid Mixing: Stabilization of Stratified Fluids in a Minichannel
Venkatesh Seenuvasan Revathi, Jeyapradhap Thirisangu, Karthick Subramani
Rayleigh-Taylor Instability (RTI) typically arises when a dense fluid is superimposed on a lighter fluid, where the desta- bilizing gravitational force acting on miscible fluids dr…

Suspension Dynamics of Droplets in Acoustic and Gravitational Fields
Jeyapradhap Thirisangu, Anjan Mahapatra, Karthick Subramani
In the field of acoustic suspension or levitation of droplets against gravity, the application of Gorkov's acoustic radiation force for small particles (within the Rayleigh limit)…

Droplets in Acoustic Fields: A Unified Theory from Migration to Splitting
Jeyapradhap Thirisangu, Varun Kumar Rajendran, Snekan Selvakannan +3
We present a comprehensive theoretical framework governing the dynamics of droplets in acoustic fields, applicable to all droplet sizes, from the Rayleigh limit (D<<lambda) and bey…
