Due to the increasingly wide application of electroosmotic flow in micromachines, this paper investigates the electroosmotic flow of the power-law fluid under high zeta potential in a cylindrical microcapillary for different dimensionless parameters. The electric potential distribution inside a cylindrical microcapillary is presented by the complete Poisson-Boltzmann equation applicable to an a...

In this paper, we explore fluid flow caused by the presence of an insoluble surfactant on a thin, incompressible power-law fluid over a horizontal substrate. The gradient in surface tension caused by the surfactant results in fluid flow away from the region where the surfactant was deposited. Work has been conducted with Newtonian fluids and surfactants; however, the extensive effect surfactant...

In this work, the effect of amphiphobic surfaces on rheological behavior and boundary slip shear thickening fluids (STFs) was investigated. The experimental results suggested viscosities were diminished, delayed weakened, an ultrahigh drag reduction obtained. Furthermore, length observed to vary with rate. Dissipative particle dynamics (DPD) simulations adopted further investigate these specifi...

BACKGROUND The epithelial-to-mesenchymal transition (EMT) of mesothelial cells was observed in patients on peritoneal dialysis and may be involved in peritoneal thickening. Conventional peritoneal dialysis fluids (PDFs) that contain glucose degradation products (GDPs), such as methylglyoxal (MGO) and formaldehyde (FA), are bioincompatible. The aim of this study is to analyse the participation o...

Increasingly restricted availability and environmental impact of mineral oils have boosted the interest in sustainable lubrication. In this study, thickening properties sodium carboxymethyl celluloses (CMCs) were investigated order to assess their potential as viscosity modifiers aqueous gear bearing fluids. The pressure, temperature shear dependence was studied at different concentrations mole...

Viscoelastic fluids exhibit rheological nonlinearity at a high shear rate. Although typical nonlinear effects, shear thinning and shear thickening, have been usually understood by variation of intrinsic quantities such as viscosity, one still requires a better understanding of the microscopic origins, currently under debate, especially on the shear-thickening mechanism. We present accurate meas...

Shear-Thickening Fluids (STFs) are a special Non-Newtonian Fluid that act like a solid when they experience a force. A simple example of this is a mixture of cornstarch and water. In this experiment, I text this mixture’s STF properties by using a ball drop to simulate an impact. By varying the ball drop height (and thus the force upon impact), and observing the bounce height, I determined wher...
