Force moments of an active particle in a complex fluid

, 2017
A generalized reciprocal theorem is formulated for the motion and hydrodynamic force moments of an active particle in an arbitrary background flow of a (weakly nonlinear) complex fluid.

Time-Periodic Weak Solutions to Incompressible Generalized Newtonian Fluids [PDF]

Journal of Mathematical Fluid Mechanics, 2021
AbstractIn this study we are interested in the Navier–Stokes-like system for generalized viscous fluids whose viscosity has a power-structure with exponentq. We develop an existence theory of time-periodic three-dimensional flows.

Effective Rheology of Immiscible Two-Phase Flow in Porous Media

, 2012
We demonstrate through numerical simulations and a mean field calculation that immiscible two-phase flow in a porous medium behaves effectively as a Bingham viscoplastic fluid.

Analysis of heat and fluid flow for peristaltic wave phenomenon in sisko fluid with temperature-dependent viscosity

Case Studies in Thermal Engineering
Peristaltic flow of Sisko fluid with temperature-dependent viscosity and viscous dissipation is considered in this paper. The constitutive equations for viscous and non-Newtonian power-law fluids are generalized to Sisko fluid.

Using the stress function in the flow of generalized Newtonian fluids through pipes and slits

, 2015
We use a generic and general numerical method to obtain solutions for the flow of generalized Newtonian fluids through circular pipes and plane slits. The method, which is simple and robust can produce highly accurate solutions which virtually match any ...

Peristaltic transport of a power-law fluid in an elastic tube

Journal of Taibah University for Science, 2018
A mathematical model is proposed to study the influence of elasticity on the peristaltic flow of a generalized Newtonian fluid in a tube. A power-law model is considered in the present study to understand the effect of elasticity on the peristaltic flow ...

Uniformly Rotating Homogeneous Rings in post-Newtonian Gravity [PDF]

, 2010
In this paper uniformly rotating relativistic rings are investigated analytically utilizing two different approximations simultaneously: (1) an expansion about the thin ring limit (the cross-section is small compared with the size of the whole ring) (2 ...

Two-layer gravity currents of generalized Newtonian fluids

Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2023
We examine gravity-driven two-layer flow of generalized Newtonian fluids. The two layers have different densities and constitutive laws, and the flow is assumed to be shallow and inertia-less. A depth-integrated model for flow over one-dimensional topography is derived with the volume fluxes written in terms of functions that depend only on the fluids’
