Sedimentation of a circular disk in power law fluids
Journal of Colloid and Interface Science, 2006The continuity and momentum equations have been solved numerically for the two-dimensional steady flow of power law fluids over a thin circular disk oriented normal to the direction of flow. Extensive results on the individual and total drag coefficients are obtained as functions of the power law flow behavior index (0.4 < or = n < or = 1.0), Reynolds ...

Spreading dynamics of power-law fluid droplets
Journal of Physics: Condensed Matter, 2009This paper aims at providing a summary of the theoretical models available for non-Newtonian fluid spreading dynamics. Experimental findings and model predictions for a Newtonian fluid spreading test are briefly reviewed. Then how the complete wetting and partial wetting power-law fluids spread over a solid substrate is examined. The possible extension

On the boundary–layer equations for power–law fluids
Proceedings of the Royal Society of London. Series A: Mathematical, Physical and Engineering Sciences, 2004Summary: We reconsider the problem of the boundary-layer flow of a non-Newtonian fluid whose constitutive law is given by the classical Ostwald-de Waele power-law model. The boundary-layer equations are solved in similarity form. The resulting similarity solutions for shear-thickening fluids are shown to have a finite-width crisis resulting in the ...

Stretching a Surface in a Rotating Power‐Law Fluid
ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, 1995The authors consider the steady flow of an incompressible power-law fluid past a horizontal stretching plate that rotates around a vertical axis. The equations are formulated for the velocity and the stress tensor. Assuming the boundary layer approximation from [the authors, Z. Angew. Math. Mech. 75, No.

Solution of Unsteady Flow of Power Law Fluids
AIAA Journal, 1972The experimental results have verified the linear behavior of the intensity of Raman scattered light as a function of specie concentration. It can be concluded that the technique is capable of identifying and measuring concentrations of individual gaseous species in a mixture during a single 10-nanosec sampling time.

Nonlinear Analysis: Theory, Methods & Applications, 1985
The paper is concerned with initial boundary value problems for the scalar equation \(u_ t(x,t)+A(u)(x,t)=v(t)\phi (x)\) in \(\Omega\) x(0,T)\(\subset {\mathbb{R}}^ 4,\) where \(A(w)=-\nabla \cdot (| \nabla w|^{p-2}\cdot \nabla w)\), \(\phi\) is given, and v is an L 2-control that is sought to minimize \[ J(v)=\int_{\Omega}| u(\cdot,T)- z(\cdot)| \quad

Alternatives to the Power-Law Fluid Model for Crosslinked Fluids
Society of Petroleum Engineers Journal, 1985AbstractMeasuring the rheological properties of crosslinked fracturing fluids is difficult but important. Fluid properties play a key role in the determination of the final geometry of die created fracture and in the distribution of proppant within the fracture; therefore, an accurate knowledge of these parameters is necessary for optimum treatment ...

POWER-LAW FLUIDS IN POROUS MEDIA
Chemical Engineering Communications, 1987An analysis is presented to describe the parallel flow of power-law fluids within a channel bounded by porous media. It is shown that there is an excess flow above the Darcy's law prediction for the porous medium region adjacent to the channel/ porous medium boundary. This also leads to a higher flow rate in the channel.

AN ADHESIVE PROBLEM FOR A POWER-LAW FLUID
Chemical Engineering Communications, 2012The flow caused by the pulling of a circular disk away from a plane rigid surface is investigated when the disk and the surface are separated by a thin layer of power-law fluid of thickness h(t). It is observed that the force exerted by the fluid on the disk is a suction force F, which tends to make the disk adhere to the rigid surface.
