Corner Flow of Power Law Fluids [PDF]
Journal of Rheology, 1989 A local analysis of the flow of power law fluids near corners is performed. The equation for the stream function is shown to allow separated solutions in plane polar coordinates. The radial behavior is shown to be algebraic and results are given for the exponent for different values of corner angle and power law exponent.

Steady flow of power-law fluids in a 1:3 planar sudden expansion [PDF]
, 2013 The laminar flow of inelastic non-Newtonian fluids, obeying the power-law model, through a planar sudden expansion with a 1:3 expansion ratio was investigated numerically using a finite volume method. A broad range of power-law indices in the range 0.2 n

Similarity solutions for unsteady shear-stress-driven flow of Newtonian and power-law fluids : slender rivulets and dry patches [PDF]
, 2011 Unsteady flow of a thin film of a Newtonian fluid or a non-Newtonian power-law fluid with power-law index N driven by a constant shear stress applied at the free surface, on a plane inclined at an angle α to the horizontal, is considered.

Results in Engineering, 2023 The presence of cuttings bed in deviated wellbores has an undesirable effect on wellbore hydraulics by reducing the open flow area. In addition, pipe eccentricity affects the annular frictional pressure gradient under such configurations.

Experiment-based Comparison of Prediction Methods for Pump Head Degradation with Viscous and Power-law Fluids [PDF]
Chemical and Biochemical Engineering Quarterly, 2022 Although several methods are known to calculate pump performance with highly viscous and non-Newtonian fluids, research has not yet determined all the key parameters of these predictions. It is unclear how these parameters depend on the pump geometry and

Instabilities of a dam-break wave of power-law fluids [PDF]
, 2023 The paper theoretically investigates the stability properties of the dam–break wave of a fluid with power–law rheology. Assuming the long–wave approximation, a depth–averaged flow model is considered.

Wall effects on the transportation of a cylindrical particle in power-law fluids [PDF]
, 2011 The present work deals with the numerical calculation of the Stokes-type drag undergone by a cylindrical particle perpendicularly to its axis in a power-law fluid.
