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…
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…
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…
