We investigate the nonlinear rheological behavior of colloidal suspensions of Laponite, a synthetic clay, driven by steady homogeneous shear strain. We show that the external drive leads to drastic slowing down of the aging dynamics or even, in some cases, in rejuvenation of the system. Under shear, after a surprisingly long time, the spontaneous aging process observed at rest is suppressed. Th...

A novel computational fluid dynamics-population balance model (CFD-PBM) for the simulation of gas mixing in activated sludge (i.e., an opaque non-Newtonian liquid) in a bubble column is developed and described to solve the problem of measuring the hydrodynamic behavior of opaque non-Newtonian liquid-gas two-phase flow. We study the effects of the inlet position and liquid-phase properties (wate...

We present a theoretical model for the characterization of behavior Newtonian and non-Newtonian fluids inside microchannel with segments different widths. This allows us to find relation required have collapsed viscosity curves in just one experiment. Diverse experiments been carried out our setup. consider hematocrit concentration samples as well blood altered solutions order modify their toni...

This article explores the influence of polymers on boundary layer flow, heat transfer, and mass transfer control non-Newtonian-based nanofluids flowing past a stretching surface. The mathematical model incorporates Oldroyd-B to analyze effects polymers, while Powell–Eyring Reiner–Philippoff viscosity models are employed study behavior non-Newtonian fluids. dispersion is adopted account for nano...

The topic of this thesis is the simulation of blood clotting using the Lattice Boltzmann method and taking into account the non-Newtonian behavior of blood. This kind of simulations could be used for the treatment of diseases like stenosis and aneurysms. Their field of application includes the diagnostic of the diseases, the planning of surgeries and the investigation of new medical treatment s...

this article investigates the nonlinear, steady boundary layer flow and heat transfer of an incompressible eyring-powell non-newtonian fluid from an isothermal sphere with biot number effects. the transformed conservation equations are solved numerically subject to physically appropriate boundary conditions using a second-order accurate implicit finite-difference keller box technique. the influ...
