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…
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),…
Solla: Towards a Speech-Oriented LLM That Hears Acoustic Context
Junyi Ao, Dekun Chen, Xiaohai Tian +6
Large Language Models (LLMs) have recently shown remarkable ability to process not only text but also multimodal inputs such as speech and audio. However, most existing models prim…
