Mixing by squirmers in stratified fluids
Vaseem A. Shaik, Gwynn J. Elfring
We find the mixing induced by a small swimming organism in a density stratified fluid. We model the swimmer as a spherical squirmer and quantify mixing through a mixing efficiency…
Densitaxis: Active particle motion in density gradients
Vaseem A. Shaik, Gwynn J. Elfring
Organisms often swim through density stratified fluids. In this Letter, we investigate the dynamics of small active particles swimming in density gradients and report theoretical e…
Confined active matter in external fields
Vaseem A. Shaik, Zhiwei Peng, John F. Brady +1
We analyze a dilute suspension of active particles confined between walls and subjected to fields that can modulate particle speed as well as orientation. Generally, the particle d…
Active particles crossing sharp viscosity gradients
Jiahao Gong, Vaseem A. Shaik, Gwynn J. Elfring
Active particles (living or synthetic) often move through inhomogeneous environments, such as gradients in light, heat or nutrient concentration, that can lead to directed motion (…
