Lagrangian evaluation of polymeric stress in viscoelastic fluids
Mohammad Majidi, Rishu Gandhi, Louison Thorens +3
Polymeric stresses in viscoelastic flows arise from the deformation of polymer chains and are commonly computed using Eulerian constitutive models, in which the conformation tensor…
Turbulent oscillation in unbalanced T-junction flows
Dongjie Jia, Arezoo Ardekani
The T-junction impinging flow occurs in many fluid dynamics systems. In particular, the T-junction micromixer has recently been widely used for nanoparticle production, where the t…
Swimmer-Types of Optimum Surface-Driven Active Particles
Rafe Md Abu Zayed, Arezoo M. Ardekani, Amir Nourhani
An optimal microswimmer with a given geometry has a surface velocity profile that minimizes energy dissipation for a given swimming speed. An axisymmetric swimmer can be puller-, p…
Rheology of concentrated suspension of fibers with load dependent friction coefficient
Monsurul Khan, Rishabh V. More, Arash Alizad Banaei +2
We numerically investigate the effects of fiber aspect ratio, roughness, flexibility, and flow inertia on the rheology of concentrated suspensions. We perform direct numerical simu…
Orientation instability of settling spheroids in a linearly density stratified fluid
Rishabh V. More, Mehdi N. Ardekani, Luca Brandt +1
Much work has been done to understand the settling dynamics of spherical particles in a homogeneous and a stratified fluid. However, the effects of shape anisotropy on the settling…
Implementing contact angle boundary conditions for second-order Phase-Field models of wall-bounded multiphase flows
Ziyang Huang, Guang Lin, Arezoo M. Ardekani
In the present work, a general formulation is proposed to implement the contact angle boundary conditions for the second-order Phase-Field models, which is applicable to -phase…
