Simulating the swimming motion of a flagellated bacterium in a microstructured bio-fluid

Arjun Sharma, Sabarish V. Narayanan, Sarah Hormozi +1

We develop a numerical framework to simulate the locomotion of a flagellated bacterium with a spheroidal head (such as Escherichia coli) in biological fluids like mucus, which are…

Convective scalar transport from spherical drops in complex shearing flows

Sabarish V. Narayanan, Ganesh Subramanian

We calculate the scalar transport rate, as characterized by the Nusselt number\,( $N u$ ), from a neutrally buoyant spherical drop in an ambient linear flow, in the absence of inertia…

A viscous drop in a planar linear flow -- the role of deformation on streamline topology

Sabarish V. Narayanan, Ganesh Subramanian

Planar linear flows are a one-parameter family, with the parameter $I^^\pm \in [- 1, 1]$ being a measure of the relative magnitudes of extension and vorticity; $I^^\pm = - 1$ , $0$ and…
