This paper presents a simple approximate continuum model for contact-line advance from Newtonian aqueous surfactant solution into oil. Geometrical complexity of the underlying solid surface and the liquid/liquid interface is included in the general f

Recovery of oil from the blocks of an initially oil-wet, naturally fractured, reservoir as a result of counter-current flow following introduction of aqueous wettability-altering surfactant into the fracture system is considered, as an example of a p

It is argued in this article that the remarkable successes achieved in simulating the flow of Newtonian fluids in complex geometries cannot currently be achieved for most important flows of complex fluids. The examples chosen to illustrate this thesi

Measurements are made of the viscoelastic properties of a wormlike micellar solution undergoing steady shearing. The wormlike micellar solution has a clearly defined Maxwell response in oscillation. The features (for example, the plateau of the elast

This paper deals with reducing the number of spatial dimensions of the models used to solve stable and unstable miscible flows in saturated and homogeneous porous media. Unstable miscible displacements occur when a fluid displaces another fluid of hi

This article first provides a brief and simple account of continuum models for transport in porous media, and of the role of length scales in passing from pore-scale phenomena to “Darcy” continuum scale representations using averaged variables. I

We present experimental findings and matching modeling concerning the effect of water droplets on the rheology of a high viscosity alkyd resin. In the flow regime where significant droplet deformation occurs, the shear viscosity of the fluid containi

We present analytical tip region solutions for fracture width and pressure when a power law fluid drives a plane strain fracture in an impermeable linear elastic solid. Our main result is an intermediate asymptotic solution in which the tip region st

Flow curves are based on uniform steady simple shear flow, whether in Couette or Poiseuille realizations. It is still often argued by many authors that, for rheologically simple fluids, a maximum in a flow curve is inadmissible on physical grounds. A
