An Experimental Approach towards Motion Modeling and Control of a Vehicle Transiting a Non-Newtonian Environment

open access: yesFractal and Fractional, 2021
The present work tackles the modeling of the motion dynamics of an object submerged in a non-Newtonian environment. The mathematical model is developed starting from already known Newtonian interactions between the submersible and the fluid. The obtained

Microfluidic Rheology of Non-Newtonian Liquids [PDF]

open access: yesAnalytical Chemistry, 2007
We investigate the rheological properties of a non-Newtonian glass-former liquid within lithographically defined microchannels in the range of temperatures above the vitrification region. The non-Newtonian behavior of the fluid, as evidenced by rotational rheology, is well described by a power law dependence of the viscosity on the shear rate.

Non‐Newtonian stokes flow with frictional boundary conditions

open access: yesMathematical Modelling and Analysis, 2007
In this work we deal with the boundary value problem for the non‐Newtonian fluid flow with boundary conditions of friction type, mostly by means of variational inequalities.

Melting of non-Newtonian phase change material in a finned triple-tube: Efficacy of non-uniform magnetic field

open access: yesCase Studies in Thermal Engineering, 2021
In this paper, a numerical study is presented on the melting process and heat transfer enhancement of a non-Newtonian phase change material (NPCM) in a double tube and a finned triple tube.

The shear-driven Rayleigh problem for generalised Newtonian fluids

open access: yes, 2014
We consider a variant of the classical ‘Rayleigh problem’ (‘Stokes’s first problem’) in which a semi-infinite region of initially quiescent fluid is mobilised by a shear stress applied suddenly to its boundary. We show that self-similar solutions for the

The thinning of lamellae in surfactant-free foams with non-Newtonian liquid phase [PDF]

open access: yes, 2008
Thinning rates of liquid lamellae in surfactant-free non-Newtonian gas–liquid foams, appropriate for ceramic or polymer melts and also in metals near the melting point, are derived in two dimensions by matched asymptotic analysis valid at small capillary

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.

Rheological Characterization of Non-Newtonian Mixtures by Pressure Pipe Tests [PDF]

open access: yes, 2021
The rheological behavior of non-Newtonian fluids in turbulent conditions is an important topic in several fields of engineering. Nevertheless, this topic was not deeply investigated in the past due to the complexity of the experimental tests for the ...
