The peculiarities of simple shear flow thinning fluids over a superhydrophobic wall consisting set parallel gas-filled grooves and solid stripes (domains with slip stick boundary conditions) are studied numerically. Carreau-Yasuda model is used to provide further insight into the problem behavior non-Newtonian having decreasing viscosity rate increase. This feature demonstrated cause nonlinear velocity profile leading apparent slip. corresponding transverse longitudinal lengths striped...
By means of time-resolved small-angle X-ray scattering, we developed an analysis methodology to assess the void volume fraction ϕv in high-density polyethylene (HDPE) during tensile testing. The specimens were first drawn up different imposed strains, and subsequently subjected stress unloading strain recovery stages. During loading stage, progressively increased with level, starting from a well-defined onset prior yield point. In particular, reached maximum 8.75 vol% for 12.5% case HDPE...
This work is focused on the mechanisms of dripping and jetting flow modes viscoelastic semi-dilute polyacrylamide aqueous solutions co-flowing with silicone oil in co-axial capillaries. A phase diagram dripping, jetting, intermediate established. It was found that mode, elongation velocity filament between terminal droplet inner capillary controlled solely by continuous rate. At same time, decrease diameter due to both stretching outflow polymer solution into droplet. In thread evolve three...
Using micro-particle image velocimetry (μPIV), the convective flow inside a silicone oil droplet was investigated in detail during its formation coaxial capillaries under co-flow water/glycerol mixture continuous phase. The analysis of μPIV measured field revealed that two characteristic areas exist formation: an inflow zone and circulation zone. intensity vortex these zones estimated by calculating average angular velocity vortices condition no shear for different dispersed phase rates...
The shear-induced dynamics of two-dimensional composite droplets in a narrow channel is investigated numerically. consist viscous inner droplet (core) and shell immersed continuous Newtonian fluid. Attention focused on studying the effects confinement at different core-to-shell radii ratios, relative viscosities medium components, interfacial tensions steady-state deformation orientation droplet. role ``sustaining'' effect due to internal core competition between near-wall shear flow...

Abstract In this work we propose a new constitutive theory to estimate the stress–strain response and softening induced by Mullins effect during stretching of filled elastomers. study, used Tobin concept where elastomers are treated as composites with hard‐domains soft‐domains is due hard domain transformation into soft stretching. Gent strain energy assumed represent behavior unfilled This representation then reformulated in order consider fillers case The proposed approach takes account...
The peculiarities of viscoelastic behavior high-density polyethylene (HDPE) subjected to the uniaxial cyclic tensions and retractions below yield point are studied. This required using three different deformation programs including (i) successive increase in strain maximum each cycle, (ii) controlled upper lower stress boundaries, (iii) fixed at backtracking points. experimental data analyzed a framework modified structure-sensitive model (Oshmyan et al., 2006, “Principles...
The classical viscoelastic constitutive equations do not simulate correctly the mechanical behavior of semi crystalline polymers, particularly in case strain rate jumping or unloading to zero stress after tensile testing. main experimental observations response polyethylene and polypropylene at small strains are reviewed. A physical model, which account for deformation-induced evolution material structure, is developed compared observations. It concluded that this model most adequate...
The peculiarities of a Newtonian fluid flow structure in microchannels with striped superhydrophobic lower wall texture are studied by means numerical modeling. In the Cassie–Baxter state, an oblique orientation such induces helicoidal streamlines micro spirals. Such favors enhancement mixing efficiency, which can be quantified using total root-mean-square deviation from microchannel axis. This characteristic was shown to nonmonotonic function tilt angle and depend strongly on thickness....
