Analytical solutions of couple stress fluid flows with slip boundary conditions

Alexandria Engineering Journal, 2014
In the present article, the exact solutions for fundamental flows namely Couette, Poiseuille and generalized Couette flows of an incompressible couple stress fluid between parallel plates are obtained using slip boundary conditions. The effect of various

Anisotropy in Homogeneous Rotating Turbulence

, 2003
The effective stress tensor of a homogeneous turbulent rotating fluid is anisotropic. This leads us to consider the most general axisymmetric four-rank ``viscosity tensor'' for a Newtonian fluid and the new terms in the turbulent effective force on large

A Class of Flows for Couple Stress Fluids

Journal of Basic & Applied Sciences, 2012
Exact solutions are derived for a class of two dimensional couple stress flows. This class consists of flows for which the vorticity distribution is characterized by the Eq. (12). The solutions are obtained by introducing the functions Ψ, H and the canonical transformation.

Pore-scale modeling of fluid-particles interaction and emerging poromechanical effects

, 2013
A micro-hydromechanical model for granular materials is presented. It combines the discrete element method (DEM) for the modeling of the solid phase and a pore-scale finite volume (PFV) formulation for the flow of an incompressible pore fluid.

Investigation of combined heat and mass transfer between vertical parallel plates in a two-layer flow of couple stress nanofluid

Open Engineering, 2016
This study is an investigation of fully-developed laminar flow in a two-layer vertical channel; one part filled with couple stress nanofluid and the other part with clear couple stress fluid. The flow is examined for combined heat and mass transfer using

Frictional Stabilities on Induced Earthquake Fault Planes at Fox Creek, Alberta: A Pore Fluid Pressure Dilemma

, 2019
Earthquakes induced during hydraulic fracturing operations have occurred in a number of locales. However, in-situ studies aimed to discern the triggering mechanism remains exclusively statistical in their nature.
