Scaling laws for hydraulic fractures driven by a power‐law fluid in homogeneous anisotropic rocks
International journal for numerical and analytical methods in geomechanics (Print), 2018This study investigates parametric space of solutions for a planar hydraulic fracture propagating in a homogeneous anisotropic rock. It is assumed that the fracture has an elliptical shape and is driven by a power‐law fluid.

Withdrawal of power law fluid films
Chemical Engineering Science, 1970Abstract The thickness of a layer of a power law fluid on a sheet, which is withdrawn from a bath, is determined for the three regimes of withdrawal conditions. The flux in viscous withdrawal is, like for a newtonian liquid, lower than the maximum possible flux on a sheet moving upwards with a certain velocity.

Consistometers rheometry of power-law viscous fluids
Journal of Non-Newtonian Fluid Mechanics, 2005This work provides a one-dimensional analytical theory for straight and axisymmetric consistometers, and helps with their use as rheometers. It is shown that these very economical and easy-to-use instruments provide an accurate characterisation of the rheological behaviour of shear-thinning, shear thickening and other materials of high apparent ...

Boundary-layer analysis of power-law fluids
Korean Journal of Chemical Engineering, 1989An exact numerical solution to the 2-D(Two-Dimensional) laminar boundary-layer equations of power-law non-newtonian fluids is obtained using a finite difference technique. No limitation has been imposed on the flow behavior index(n) or generalized Prandli number As a test case, velocity and temperature fields around a circular cylinder in crossflow ...

Power law fluid flow over spheroidal particles
Industrial & Engineering Chemistry Research, 1994The equations of motion have been solved numerically for the incompressible power law fluid flow past spherical and spheroidal solid particles. The finite element technique has been employed to obtain the velocity and pressure fields prevailing around a particle. These have been further processed to evaluate the individual contributions of pressure and

Power‐law fluids flow through multiparticle system
The Canadian Journal of Chemical Engineering, 1968AbstractA study on the flow of power‐law fluids through a multi‐particle system including both fixed bed and fluidized bed is presented. Equations for the pressure drop, the minimum fluidization velocity, and the bed expansion are obtained by extending the Blake‐Kozeny's equation for the pressure drop through packed beds to power‐law fluids.

Convective wall plume in power-law fluids
International Journal of Heat and Mass Transfer, 1993Abstract This paper considers the steady-state free convection flow arising from a line thermal source positioned at the leading edge of a vertical adiabatic surface embedded in polymeric fluids. The wall plume depends on two parameters : the index of the power-law fluid (n) and the generalized Prandtl number (Pr).

The Spreading of Power-Law Fluids
2001A 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, 1990ABSTRACTOrifice 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 ...
