We measured the static and dynamic (complex) shear viscosity of a single layer complex plasma by applying, respectively, a stationary and a periodically modulated shear stress induced by the light pressure of manipulating laser beams. Under static conditions the shear viscosity reproduced the ...
Dt= KbT / 3πηdh When the Boltzmann constant (Kb), Temperature (T) and bulk viscosity (η) are recognized values and only the particle size, dh, is a property of the particle. For a recognized scattering angle, θ and refractive index, n, the scattering vector q is determined from t...
In materials judging experiments, we found that human performance with rotating video stimuli is higher than that with static stimuli (simple images). Subsequently, we compared the developed model derived from motion coherency to human rating performance for transparency and specular reflection. The ...
Static and dynamic performance parameters of three-lobe fluid film bearing, operating with TiO 2 -based non-Newtonian lubricant, are obtained. The Krieger–Dougherty model of effective is used to obtain the viscosity of nanolubricant for a fixed concentration of nanoparticle dispersed in base lubrican...
A powerful application of the Reynolds number is the identification of conditions of dynamic similarity—experiments with very small or very large specimen can be impractical, but a suitable adjustment of the fluid viscosity enables accurate experiments with scaled models of more convenient size. In th...

I am trying to run a calculation to work out the overall heat transfer coefficient of an arbitrary ten plate exchanger where the fluid is not determined using Re=puD/mu where mu is dynamic viscosity. When mu is such a strong function of temperature how should I determine which valye to us...
Static mixers are effective with low-to-medium viscosity products. However, they may not achieve a sufficiently homogeneous mix under certain conditions: When the viscosity of the different adhesive components varies significantly. When the viscosity is very high or the components are strongly ...
The positional control of these valves usually presents a challenge, since they present nonlinearities as dead zones, hysteresis, and static and dynamic friction. Among these nonlinearities, we can mention the occurrence of the grip and slip (stick-slip) phenomenal on the valve stem due to static...
According to the following equation (Eqn 1) [45], the average flow-induced shear stress (τw) on sample surface can be roughly calculated:(1)τw=6ηQH2WWhere η is the shear viscosity of the fluid (1.006 mPa·s), Q is the flow rate of the fluid, H is the height of fluid ...
