On the convergence rate of the Kačanov scheme for shear-thinning fluids [PDF]
Calcolo, 2021 AbstractWe explore the convergence rate of the Kačanov iteration scheme for different models of shear-thinning fluids, including Carreau and power-law type explicit quasi-Newtonian constitutive laws. It is shown that the energy difference contracts along the sequence generated by the iteration. In addition, an a posteriori computable contraction factor

Shear-Thinning Fluid Flow in Variable-Aperture Channels [PDF]
Water, 2020 Non-Newtonian fluid flow in a single fracture is a 3-D nonlinear phenomenon that is often averaged across the fracture aperture and described as 2-D. To capture the key interactions between fluid rheology and spatial heterogeneity, we adopt a simplified geometric model to describe the aperture variability, consisting of adjacent one-dimensional ...

Liquid–Liquid Flows with Non-Newtonian Dispersed Phase in a T-Junction Microchannel
Micromachines, 2021 Immiscible liquid–liquid flows in microchannels are used extensively in various chemical and biological lab-on-a-chip systems when it is very important to predict the expected flow pattern for a variety of fluids and channel geometries.
