Collision efficiency of rapidly settling particle pairs in a turbulent flow
Pijush Patra, Donald L. Koch, Anubhab Roy
We investigate the collision dynamics of hydrodynamically interacting inertialess spherical particle pairs sedimenting in a homogeneous isotropic turbulent flow. The analysis focus…
Orientation of Finite Reynolds Number Anisotropic Particles Settling in Turbulence
Anubhab Roy, Stefan Kramel, Udayshankar Menon +2
We present experimental and computational results for the orientation distributions of slender fibers and ramified particles settling in an isotropic turbulent flow. The rotational…
Electroconvective flow in presence of polyethylene glycol oligomer additives
Arpita Sharma, Ankush Mukherjee, Alexander Warren +4
Metal electrodeposition in batteries is fundamentally unstable and affected by different instabilities depending on operating conditions and chemical composition. Particularly at h…
Suppression of electroconvection due to van der Waals attraction of polymer additives towards the metal electrode
Ankush Mukherjee, Lynden A. Archer, Donald L. Koch
Electroconvection in rechargeable batteries enhances the growth of dendrites at the electrode surface. The addition of low molecular weight polymers to the electrolyte in batteries…
Steady state extensional rheology of a dilute suspension of spheres in a dilute polymer solution
Arjun Sharma, Donald L. Koch
We investigate the steady-state extensional rheology of a dilute suspension of spherical particles in a dilute polymer solution. For a particle-free polymeric fluid, in addition to…
Suppression of Electroconvective and Morphological Instabilities by an Imposed Cross Flow of the Electrolyte
Gaojin Li, Alex Townsend, Lynden A. Archer +1
Electroconvection and its coupling with a morphological instability are important in many applications, including electrodialysis, batteries and fuel cells. In this work, we study…
Slender body theory for particles with non-circular cross-sections
Neeraj Sinai Borker, Donald L. Koch
This paper presents a theory to obtain the force per unit length acting on a slender filament with a non-circular cross-section moving in a fluid at low Reynolds number. Using a re…
Clustering of Rapidly Settling, Low-Inertia Particle Pairs in Isotropic Turbulence. II. Comparison of Theory and DNS
Sarma L. Rani, Rohit Dhariwal, Donald L. Koch
Part I of this study presented a stochastic theory for the clustering of monodisperse, rapidly settling, low-Stokes-number particle pairs in homogeneous isotropic turbulence. The t…
Clustering of Rapidly Settling, Low-Inertia Particle Pairs in Isotropic Turbulence. I. Drift and Diffusion Flux Closures
Sarma L. Rani, Vijay K. Gupta, Donald L. Koch
In this two--part study, we present the development and analysis of a stochastic theory for characterizing the relative positions of monodisperse, low-inertia particle pairs that a…
