Inertial active particles in a Poiseuille flow: negative mobility and particle separation
Ankit Gupta, P. S. Burada
The diffusive behavior of small entities is strongly influenced by the flow of the surrounding medium, which is ubiquitous in natural and artificial environments. In this study, we…
Entropic active particle transport in pulsating 3D geometries
Rahul Sinha, Ankit Gupta, P. S. Burada
We study the transport of active Brownian particles (ABPs) in three-dimensional (3D) oscillatory geometries, which are spatially periodic. We establish a generalized Fick-Jacobs ap…
Active chiral rotors: hydrodynamics and chemotaxis
R. Maity, Snigdha Thakur, P. S. Burada
An active chiral rotor is a spherical object that can generate chiral flows in a fluid by rotating about an axis. For example, if the flow around the upper hemisphere of the chiral…
Chiral swimmer with a regular arbitrary active patch
Shiba Biswas, P. S. Burada, G. P. Raja Sekhar
We investigate the low Reynolds number hydrodynamics of a spherical swimmer with a predominantly hydrophobic surface, except for a hydrophilic active patch. This active patch cover…
Role of obstacle softness in the diffusive behavior of active Particles
Ankit Gupta, P. S. Burada
We numerically investigate the diffusive behavior of active Brownian particles in a two-dimensional confined channel filled with soft obstacles, whose softness is controlled by a p…
