Thermo-fluidic significance of non Newtonian fluid with hybrid nanostructures

open access: yesCase Studies in Thermal Engineering, 2021
The main purpose of this investigation is to analyze the flow and heat transfer behavior of a non Newtonian fluid (Oldroyd B fluid) with hybrid nanostructure subject to externally inclined magnetic field. Cattaneo Christov heat flux model is incorporated

Superchaotropic Nano‐ion Binding as a Gelation Motif in Cellulose Ether Solutions

open access: yesAngewandte Chemie International Edition, Volume 62, Issue 3, January 16, 2023., 2023
Nano‐ions, like polyoxometalates and boron clusters, co‐assemble strongly with non‐ionic solutes in water driven by the chaotropic effect. Here, nano‐ion assembly with non‐ionic cellulose ethers (CE) is shown to result in unprecedented thickening effects and gelation of CE‐solutions. An interplay of electrostatic repulsion and attraction between chains

New analytical equations for productivity estimation of the cyclic CO2-assisted steam stimulation process considering the non-Newtonian percolation characteristics

open access: yesJournal of Petroleum Exploration and Production Technology, 2018
The research course in the estimation of productivity of cyclic steam stimulation wells can be divided into three stages: (a) the mobility of heavy oil in the cold area is neglected, (b) the mobility of heavy oil in the cold area is considered—however ...

On the resolvability of the dynamics of one fluid flow via a testing fluid in a two-fluids flow model [PDF]

open access: yesarXiv, 2022
In this work, by considering an isentropic fluid-fluid interaction model with a large symmetric drag force, a commonly used simplified two-fluids flow model is justified as the asymptotic limit. Equations for each fluid component with an interaction term are identified in addition to the simplified two-fluids flow model, which can be used to resolve ...

Multi‐scale study of the structuration of candle blends with a high content of vegetable fats to replace paraffins: Effect of 12‐hydroxystearic acid content

open access: yesJournal of the American Oil Chemists' Society, Volume 99, Issue 12, Page 1137-1150, December 2022., 2022
Abstract The aim is to replace mineral waxes with vegetable fats as an organogel for candle manufacturing while keeping the same texture. The physico‐chemical characteristics of renewable vegetable raw materials differ from those of mineral waxes and consequently the structure of the blends in which they are used is modified.

Electrowriting of silk fibroin: Towards 3D fabrication for tissue engineering applications

open access: yesJournal of Applied Polymer Science, Volume 140, Issue 4, January 20, 2023., 2023
Abstract Electrowriting (EW) successfully combines the principles of two widely studied biofabrication techniques; 3D printing and electrospinning, and is capable of producing complex architectures, with submicron resolutions. However, the EW process so far is limited mainly to thermoplastic polymers of synthetic origin such as poly ε‐caprolactone ...

Numerical Simulation of Gas-Liquid Flow in a Bubble Column by Intermittent Aeration in Newtonian Liquid/Non-Newtonian Liquid

open access: yesInternational Journal of Chemical Engineering, 2018
The dynamic behaviors of gas-liquid two-phase flow were simulated in a lab-scale intermittent bubble column by Euler-Euler two-fluid model coupled with the PBM (population balance model) using two different liquid phases, i.e., Newtonian fluid (water ...

The cost of swimming in generalized Newtonian fluids: Experiments with C. elegans [PDF]

open access: yesJ. Fluid Mech. (2016), vol. 800, pp. 753-765, 2016
Numerous natural processes are contingent on microorganisms' ability to swim through fluids with non-Newtonian rheology. Here, we use the model organism Caenorhabditis elegans and tracking methods to experimentally investigate the dynamics of undulatory swimming in shear-thinning fluids. Theory and simulation have proposed that the cost of swimming, or

On a degenerate parabolic equation with Newtonian fluid∼non-Newtonian fluid mixed type

open access: yesJournal of Inequalities and Applications, 2021
We study the existence of weak solutions to a Newtonian fluid∼non-Newtonian fluid mixed-type equation u t = div ( b ( x , t ) | ∇ A ( u ) | p ( x ) − 2 ∇ A ( u ) + α ( x , t ) ∇ A ( u ) ) + f ( u , x , t ) .
