Electrokinetically modulated peristaltic transport of power-law fluids.
Microvascular Research, 2016The electrokinetically modulated peristaltic transport of power-law fluids through a narrow confinement in the form of a deformable tube is investigated. The fluid is considered to be divided into two regions - a non-Newtonian core region (described by the power-law behavior) which is surrounded by a thin wall-adhering layer of Newtonian fluid.

Helical flow of power‐law fluids
AIChE Journal, 1990A numerical solution is presented for the helical flow of a power-law fluid between coaxial cylinders. The solution is valid for isothermal steady creeping flow in an annular space of arbitrary thickness. Results are presented in the form of relations between dimensionless integral flow characteristics (e.g.

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

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 ...

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.

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 ...

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

Entrance effects for power‐law fluid
Polymer Engineering & Science, 1994AbstractEntrance pressure losses for the creeping flow of a power‐law fluid are calculated for an abrupt contraction of ratio 2, 4, 8 and ∞ for both the axisymmetric and planar cases using P2P1 and PP1 finite elements. Contrary to some earlier findings in the literature, the entrance pressure loss obtained by using the two different types of finite ...
