The Spreading of Power-Law Fluids

2001
A thin-film formulation for the capillary-driven spreading of a power-law fluid is analysed to clarify, in particular, the relationship between macroscopic and microscopic contact angles and the dynamics of spreading in the completely-wetting case. The Newtonian fluid emerges as a critical case within the one-parameter family of evolution equations ...

ORIFICE DISCHARGE COEFFICIENTS FOR POWER‐LAW FLUIDS

Journal of Food Process Engineering, 1990
ABSTRACTOrifice discharge coefficients for non‐Newtonian (power‐law) fluids (5, 7.5 and 10% corn starch solutions) were measured using a closed end pipe with different orifice diameters. Results indicate that orifice discharge coefficients, found to be in the range of 0 – 0.7, are a function of the orifice diameter, fluid velocity in the orifice and ...

Blade coating of a power-law fluid

Physics of Fluids, 1999
In this paper we re-examine the problem of applying a thin layer of a power-law fluid to a solid substrate by means of a simple blade coater. Specifically we use lubrication theory to examine steady plane flow of a power-law fluid in the narrow nonuniform channel formed between a fixed blade of prescribed shape and a plane substrate moving parallel to ...

Turbulent pipe flow of power-law fluids

International Communications in Heat and Mass Transfer, 1997
Abstract This paper reports on the numerical computation of the turbulent flow of power-law fluids in smooth circular tubes. The turbulence is represented by means of a modified version of an existing two-equation turbulence model. Numerical results are presented for the fully-developed friction factor and velocity profile, and compared with ...

Relaxation Dynamics of Non-Power-Law Fluids

International Journal of Thermophysics, 2013
The relaxation of non-Newtonian liquids with non-power-law rheology on partially wetted surfaces is rarely investigated. This study assesses the relaxation behavior of 14 partial wetting systems with non-power-law fluids by sessile drop method. These systems are two carboxymethylcellulose sodium solutions on two kinds of slides, cover glass, and ...

Hiemenz Magnetic Flow of Power-Law Fluids

Journal of Applied Mechanics, 1974
The Galerkin approximative technique is used to solve the problem of stagnation in plane flow, the so-called “Hiemenz flow”, of a non-Newtonian power-law fluid in presence of a constant transverse magnetic field. The influence of the magnetic field strength on the wall shear stress is analyzed.

Alternatives to the Power-Law Fluid Model for Crosslinked Fluids

Society of Petroleum Engineers Journal, 1985
AbstractMeasuring 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 ...

Sedimentation of a circular disk in power law fluids

Journal of Colloid and Interface Science, 2006
The 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 ...

Creeping flow of power‐law fluid over newtonian fluid sphere

AIChE Journal, 1968
AbstractA technique which is a combination of Galerkin's method and variational principle was developed and used for the approximate solution of creeping flow of power‐law fluid over a Newtonian fluid sphere. The stream functions (both internal and external) and drag coefficient are expressed in terms of three parameters: the flow behavior index of the
