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…

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…
