The orientation dynamics of a massive ellipsoid in simple shear flow
Giridar Vishwanathan, Sangamesh Gudda, Ganesh Subramanian
The orientation dynamics of a massive rigid ellipsoid in simple shear flow of a Newtonian fluid is investigated in detail. The term `massive' refers to dominant particle inertia, a…
Synchronous oscillatory electro-inertial focusing of microparticles
Giridar Vishwanathan, Gabriel Juarez
Here, results are presented on the focusing of m polystyrene particle suspensions using a synchronous oscillatory pressure-driven flow and oscillatory electric field in a mi…
Multi-curvature viscous streaming: flow topology and particle manipulation
Yashraj Bhosale, Giridar Vishwanathan, Tejaswin Parthasarathy +2
Viscous streaming refers to the rectified, steady flows that emerge when a liquid oscillates around an immersed microfeature, typically a solid body or a bubble. The ability of suc…
Generation and application of sub-kilohertz oscillatory flows in microchannels
Giridar Vishwanathan, Gabriel Juarez
We present a user-friendly and versatile experimental technique that generates sub-kilohertz sinusoidal oscillatory flows within microchannels. The method involves the direct inter…
Steady streaming flows in viscoelastic liquids
Giridar Vishwanathan, Gabriel Juarez
We discuss experimental investigations on steady streaming flows of dilute and semi-dilute polymer solutions in microfluidic devices. The effect of non-Newtonian behavior on steady…
Steady streaming viscometry of Newtonian liquids in microfluidic devices
Giridar Vishwanathan, Gabriel Juarez
We report a novel technique capable of measuring the kinematic shear viscosity of Newtonian liquids with steady streaming in microfluidic devices. This probe-free microrheological…
