Pore-scale permeability prediction for Newtonian and non-Newtonian fluids [PDF]

open access: yesSolid Earth, 2019
The flow of fluids through porous media such as groundwater flow or magma migration is a key process in geological sciences. Flow is controlled by the permeability of the rock; thus, an accurate determination and prediction of its value is of crucial ...

Simulation Analysis of Power Consumption and Mixing Time of Pseudoplastic Non-Newtonian Fluids with a Propeller Agitator

open access: yesEnergies, 2022
In order to study the effect of a high twist rate propeller on the flow field characteristics of pseudoplastic non-Newtonian fluids, the numerical simulation method was used to analyze the mixing flow field of pseudoplastic non-Newtonian fluids at ...

Microrheometer for Biofluidic Analysis: Electronic Detection of the Fluid-Front Advancement

open access: yesMicromachines, 2021
The motivation for this study was to develop a microdevice for the precise rheological characterization of biofluids, especially blood. The method presented was based on the principles of rheometry and fluid mechanics at the microscale.

A Fractal Rheological Model for SiC Paste using a Fractal Derivative [PDF]

open access: yesJournal of Applied and Computational Mechanics, 2021
The rheological property plays an important role in a free-form extrusion 3D printing process, no rheological model was available in open literature that could effectively take into account effects of both the non-Newtonian viscosity and the ...

The inertial dynamics of thin film flow of non-Newtonian fluids [PDF]

open access: yes, 2007
Consider the flow of a thin layer of non-Newtonian fluid over a solid surface. I model the case of a viscosity that depends nonlinearly on the shear-rate; power law fluids are an important example, but the analysis here is for general nonlinear ...

Stress Overshoot Analysis in Flow Start-Up Tests: Aging Time Fitting of the Different Gel-Based Drilling Fluids

open access: yesGels
Drilling fluids are essential for maintaining cutting suspension during drilling, exhibiting gel-like behavior at rest and liquid-like behavior under shearing. These fluids display shear-thinning behavior, yield stress, and thixotropy.

The Bouncing Jet: A Newtonian Liquid Rebounding off a Free Surface [PDF]

open access: yes, 2007
We find that a liquid jet can bounce off a bath of the same liquid if the bath is moving horizontally with respect to the jet. Previous observations of jets rebounding off a bath (e.g.

Natural convection of viscoplastic fluids in side-heated open cavities

open access: yesCase Studies in Thermal Engineering
This study considers the natural convection process of viscoplastic fluid in a side-open cavity filled with conductive solid blocks, which are uniformly distributed and form a square lattice.

Active colloids in complex fluids [PDF]

open access: yes, 2016
We review recent work on active colloids or swimmers, such as self-propelled microorganisms, phoretic colloidal particles, and artificial micro-robotic systems, moving in fluid-like environments. These environments can be water-like and Newtonian but can
