objective(s): one applications of nanotechnology is in the area of medicine which is called nanomedicine. primary instruments in nanomedicine can help us to detect diseases and used for drug delivery to inaccessible areas of human tissues. an important issue in simulating the motion of nanoparticles is modeling blood flow as a newtonian or non-newtonian fluid. sometimes blood flow is simulated ...

Abstract The electroosmotic flow of non-Newtonian fluid–Eyring fluid in microparallel pipes under high zeta potential driven by the combination pressure and electric force is studied. Without using Debye–Hückel (DH) linear approximation, numerical solutions distribution velocity obtained finite difference method are compared with analytical approximate DH approximation. results show that this a...

A stagnation-point flow of a Powell–Eyring nanofluid along vertical stretching surface is examined. The buoyancy force effect due to mixed convection taken into consideration with the Brownian motion and thermophoresis effect. investigated under active passive controls nanoparticles at surface. associating partial differential equations are converted set nonlinear, ordinary using similarity con...

The present article addresses the steady incompressible convective flow of kinetic theory-based Eyring–Powell fluid conveying nano-sized particle from a vertical plate with boundary condition and distribution nanoparticles fraction over its surface. Cattaneo–Christov model is imposed to scrutinize heat transfer analysis. A revised Buongiorno adopted, which considers zero nanoparticle flux at wa...

The shear viscosity of liquid copper is studied using nonequilibrium molecular-dynamics simulations under planar shear flow conditions. We examined variation of viscosity as function of shear rate at a range of pressures (ca. 0 - 40 GPa). We analyzed these results using eight different phenomenological models and find that the observed non-Newtonian behavior is best described by the Powell-Eyri...
