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…
Using graph neural networks to predict many-body interactions in amorphous materials
Mehryar Jannesari Ghomsheh, Donald L. Koch, Sarah Hormozi
Many-body interactions govern the complex behavior of many amorphous materials, from metallic glasses to biological tissues, yet are often replaced by pairwise additive frameworks…
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…
Stress analysis of dilute particle suspensions in non-Newtonian fluids with efficient evaluation in the weakly non-Newtonian limit
Arjun Sharma, Donald L. Koch
We present a semi-analytical framework to compute the suspension stress in dilute particle-laden non-Newtonian fluids, separating Newtonian and non-Newtonian contributions. The ens…
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…
