Shear rate versus shear stress relationship for power-law fluid: (A) pseudoplastic power-law fluid, and (B) dilatants power-law fluid. (ii) Power-Law Models: Power-law fluid can be defined as a fluid in which the shear stress at any point is proportional to the rate of shear at ...
The predictive LSSVM model enjoys a supervised learning paradigm and leads to the highest accuracy, while the physically originated CFD approach captures more consistently the nonlinear behavior of PLR versus key system features. Following the validation of our models, we study the less understood ...
If the fluid is newtonian, the experimental plot of &tgr; versus will be a straight line. The constant of proportionality is called the viscosity μ of the fluid, as stated in Eq. (2). (2)The viscosity coefficients of common fluids vary by several orders of magnitude.SeeFluid flow,Fluid...
Photo-cross-linking versus coordinative cross-linking Both irradiation and complexation lead to enhanced viscosity and eventual non-Newtonian flow of the solutions, indicating the formation of cross-links, which... R Schinner,T Wolff - 《Colloid & Polymer Science》 被引量: 16发表: 2001年 ...
“Methods” section). As a note, it is difficult to obtain the force versus displacement response of micro samples as a function of frequency directly. Hence, a numerical method was first employed to estimate the variation of the amplitude of the force for a 2D unit cell (see the “...

The effect of non-Newtonian blood flow on the value of wall shear stress (WSS) of an intracranial aneurysm was investigated using computational fluid dynamics. For cerebral arteries, blood is often assumed to behave as a Newtonian fluid, though the effects of non-Newtonian flow on the prediction...
Rheological models are used to determine rheological parameters such as shear stress, yield stress, flow index, infinite, zero-rate viscosities, and flow consistency index, which depict the general flow behaviour of the fluid. Typical plots of rheological models (shear stress versus shear rate) is...
non-newtonian fluidmass transfer coefficientThe current study reports on a series of ultrafiltration experiments using newtonian and non-newtonian fluids (pectine, xanthan and polyacrylamide solutions). For non-newtonian pseudoplastic fluids, the shape of the plot of flux versus log(bulk concentration)...
