An inertial slender-body theory
Anmol Joshi, Anubhab Roy, Arjun Sharma +1
We present a fully inertial slender-body theory (SBT) that incorporates the effect of fluid inertia on the scale of the length (the "outer" region) as well as the characteristic di…
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…
Extensional rheology of dilute suspensions of spheres in polymeric liquids
Arjun Sharma, Donald L. Koch
The extensional rheology of dilute suspensions of spheres in viscoelastic or polymeric liquids is studied computationally. At low polymer concentration (c) and Deborah number (De),…
Sedimentation and shear-induced dynamics of spheroids in fluids with spatial viscosity variations
Arjun Sharma, Peter A. Bosler, Rama Govindarajan +1
A generalized reciprocal theorem is used to relate the force and torque induced on a particle in an inertia-less fluid with small variation in viscosity to integrals involving Stok…
Finite difference method in prolate spheroidal coordinates for freely suspended spheroidal particles in linear flows of viscous and viscoelastic fluids
Arjun Sharma, Donald L. Koch
A finite difference scheme is used to develop a numerical method to solve the flow of an unbounded viscoelastic fluid with zero to moderate inertia around a prolate spheroidal part…
Rotation of a fiber in simple shear flow of a dilute polymer solution
Arjun Sharma, Donald L. Koch
The motion of a freely rotating prolate spheroid in a simple shear flow of a dilute polymeric solution is examined in the limit of large particle aspect ratio, . A regular pertu…
