Orientational dynamics and rheology of active suspensions in weakly viscoelastic flows
Akash Choudhary, Sankalp Nambiar, Holger Stark
Microswimmer suspensions in Newtonian fluids exhibit unusual macroscale properties, such as a superfluidic behavior, which can be harnessed to perform work at microscopic scales. S…
On the cross-streamline lift of microswimmers in viscoelastic flows
Akash Choudhary, Holger Stark
The current work studies the dynamics of a microswimmer in pressure-driven flow of a weakly viscoelastic fluid. Employing the second-order fluid model, we show that the self-propel…
How inertial lift affects the dynamics of a microswimmer in Poiseuille flow
Akash Choudhary, Subhechchha Paul, Felix Rühle +1
We analyze the dynamics of a microswimmer in pressure-driven Poiseuille flow, where fluid inertia is small but non-negligible. Using perturbation theory and the reciprocal theorem,…
Self-propulsion in 2D Confinement: Phoretic and Hydrodynamic Interactions
Akash Choudhary, K. V. S. Chaithanya, Sébastien Michelin +1
Chemically active Janus particles generate tangential concentration gradients along their surface for self-propulsion. Although this is well studied in unbounded domains, the analy…
Comment on "Migration of an electrophoretic particle in a weakly inertial or viscoelastic shear flow"
Akash Choudhary, T. Renganathan, S. Pushpavanam
A recent article (Khair and Kabarowski; Phys. Rev. Fluids 5, 033702) has studied the cross-streamline migration of electrophoretic particles in unbounded shear flows with weak iner…
Motion of an active particle in a linear concentration gradient
Prathmesh M. Vinze, Akash Choudhary, S. Pushpavanam
Janus particles self-propel by generating local tangential concentration gradients along their surface. These gradients are present in a thin layer whose thickness is small compare…
Non-Newtonian effects on the slip and mobility of a self-propelling active particle
Akash Choudhary, T. Renganathan, S. Pushpavanam
Janus particles propel themselves by generating concentration gradients along their active surface. This induces a flow near the surface, known as the diffusio-osmotic slip, which…
Inertial migration of an electrophoretic rigid sphere in a two-dimensional Poiseuille flow
A. Choudhary, T. Renganathan, S. Pushpavanam
In this work, we analyze the inertial migration of an electrophoretic particle in a 2-D Poiseuille flow with an electric field applied parallel to the walls. For a thin electrical…
