shear rate

By contrast, the viscosity of a melt of a plastic at a constant temperature changes markedly as the shear rate changes.

The formulations of the shear stresses and shear rate are given. The position on which the maximum shear stress acts is determined.

To understand and control melt processes, it is necessary to define the way in which melt viscosity changes with temperature and shear rate.

As the shear rate increased, the slurry viscosity fell and dropped greatly at the early stages of shear rate decrease.

The viscometer was composed of mechanical rotating parts creating different shear rate, a sample cup and a cone plank.

Cavity "B" is short, so plastic is still moving, shear rate is high, and viscosity is low, perhaps like cold molasses.

This paper presents the working principle, structure, characteristics of viscometer at a high shear rate of drilling fluid.

The rheology of a thermoplastics melt is complex, being very dependent on temperature and shear rate.

As the shear rate increased, the apparent viscosity of the solution gradually decreased.

Results showed that more dispersion phase caused droplet size bigger, droplet size is influenced by the shear rate and the elastic mod. . .

During filling of each cavity, the shear rate is high, viscosity is low (easy flowing), and all is fine.

The effective viscosity and elastic viscosity increased as the shear rate increased.

The shear rate is a measure of how fast the melt passes through a channel or orifice.

The shear stress and apparent viscosity of the masterbatch decreased with the increase of the shear rate and temperature.

Under the experimental shear rate, the macroscopical rheological behaviors of HAPS show shear thinning and shear thickening.

the extrusion swelling increased as the shear rate increased.

At low shear rate, the blood of human body perform as Casson fluid, but at high shear rate incline toward Newtonian fluid.

When the shear rate was high, the cell morphology could be improved by applying a weak vibration, no matter what the foaming system was.

As the shear rate increased the elongation at break increased and the tensile strength increased at first but decreased finally.

Some equations of shear rate estimation for Newtonian fluid and the power law fluid were derived.

With the increase of shear rate, the volume of foaming oil increases, Half-life grows.

viscous flow activation energy with the shear rate increases.

A fluid in which the shear rate is directly proportional to the shear stress.

Based on the numerical simulation of instantaneous static flow fields, the shear rate field and pressure field are analyzed.

The effects of shear rate, relaxation time and slip length on extrudate swell ratio were investigated using simulation.

Some flow parameters, such as mean velocity, fluctuating velocity distribution, flow patterns, shear rate and Reynolds stress were obtained.

The flowactive energy decreases with the increase of the shear rate.

When the shear rate is relatively low, the increased pressure can increase aphron fluid viscosity.

The flowage mode is judged according to the shear rate in the pipeline.

A simple fluid such as water has a constant viscosity value regardless of shear rate.
