Far-field approximations for multi-timescale microswimmers near a boundary
Sara Drummond-Curtis, Mohit P. Dalwadi, Benjamin J. Walker
Hydrodynamic interactions with boundaries can significantly affect the trajectories of microscale swimmers. In simple swimmer models, a common assumption is that swimmer shape rema…

Rapidly yawing spheroids in viscous shear flow: Emergent loss of symmetry
Mohit P. Dalwadi
We investigate the emergent three-dimensional (3D) dynamics of a rapidly yawing spheroidal swimmer interacting with a viscous shear flow. We show that the rapid yawing generates no…

A homogenised model for dispersive transport and sorption in a heterogeneous porous medium
Lucy C Auton, Mohit P. Dalwadi, Ian M. Griffiths
When a fluid carrying a passive solute flows quickly through porous media, three key macroscale transport mechanisms occur. These mechanisms are diffusion, advection and dispersion…
