Variability of Energy Dissipation and Shear Rate with Geometry in Unbaffled Surface Aerator

open access: yesBulletin of Chemical Reaction Engineering & Catalysis, 2009
mixing in surface aerators. At constant dynamic variables (rotational speed), both  and γ are greatly affected by the geometric parameters (impeller diameter, cross-sectional area of the tank, liquid height, rotor blade length and immersion height).

Shear Strength of Clay at Different Shear Rates [PDF]

open access: yesJournal of Geotechnical and Geoenvironmental Engineering, 2015
AbstractA test procedure that involved shearing soil specimens at different shear rates was proposed to study the effect of shear rate on the strength recovery of three natural clays. The obtained results indicated that an increase in shear strength occurred when the shear rate decreased.

Assessment of phenomenological models for viscosity of liquids based on nonequilibrium atomistic simulations of copper [PDF]

open access: yes, 2005
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).

Shear Rate and Permeability in Water Flooding [PDF]

open access: yesTransport in Porous Media, 2008
Water breakthrough during oil recovery can be inhibited by the use of novel shear-induced structure additives. These affect the shear rate experienced by fluid inside the rock matrix. We relate this to the permeability for the purpose of applying these novel non-Newtonian materials which thicken viscosity only in the shear range associated with the ...

AT1R blocker prevents mental stress induced retrograde blood flow in overweight/obese men

open access: yesPhysiological Reports, 2023
The main goal was to determine the impact of mental stress (MS) on blood flow regulation in overweight/obese men. Fourteen overweight/obese men (27 ± 7 years; 29.8 ± 2.6 kg/m2) participated in two randomized experimental sessions with oral administration

Rheology and ultrasonic properties of Pt57.5Ni5.3Cu14.7P22.5 liquid [PDF]

open access: yes, 2007
The equilibrium and nonequilibrium viscosity and isoconfigurational shear modulus of Pt57.5Ni5.3Cu14.7P22.5 supercooled liquid are evaluated using continuous–strain-rate compression experiments and ultrasonic measurements. By means of a thermodynamically-

Whole blood viscosity modeling using power law, Casson, and Carreau Yasuda models integrated with image scanning U-tube viscometer technique [PDF]

open access: yesSongklanakarin Journal of Science and Technology (SJST), 2017
This study presented the image scanning U-tube viscometer technique to measure the whole blood viscosity. Two different constitutive models, power law and Casson, were selected to calculate blood viscosity.
