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\,(), 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 being a measure of the relative magnitudes of extension and vorticity; , and $1…
A swimming bacterium in a two-fluid model of a polymer solution
Sabarish V. Narayanan, Donald L. Koch, Sarah Hormozi
We analyse the motion of a flagellated bacterium in a two-fluid medium using slender body theory. The two-fluid model is useful for describing a body moving through a complex fluid…
