Characteristics of stratified flows of Newtonian/non-Newtonian shear-thinning fluids
, 2017 Exact solutions for laminar stratified flows of Newtonian/non-Newtonian shear-thinning fluids in horizontal and inclined channels are presented. An iterative algorithm is proposed to compute the laminar solution for the general case of a Carreau non ...

A three-dimensional immersed boundary method for non-Newtonian fluids [PDF]
, 2018 Fluid-structure-interaction (FSI) phenomenon is common in science and engineering. The fluid involved in an FSI problem may be non-Newtonian such as blood. A popular framework for FSI problems is Peskin's immersed boundary (IB) method.

Micropropulsion and microrheology in complex fluids via symmetry breaking
, 2012 Many biological fluids have polymeric microstructures and display non-Newtonian rheology. We take advantage of such nonlinear fluid behavior and combine it with geometrical symmetry-breaking to design a novel small-scale propeller able to move only in ...

Non-Newtonian effects in the peristaltic flow of a Maxwell fluid [PDF]
, 2001 We analyzed the effect of viscoelasticity on the dynamics of fluids in porous media by studying the flow of a Maxwell fluid in a circular tube, in which the flow is induced by a wave traveling on the tube wall.

Modeling and numerical simulation of non-Newtonian arterial blood flow for mild to severe stenosis
Alexandria Engineering Journal, 2023 The fundamental cause of coronary heart disease is thought to be atherosclerosis. Blood flow in arteries under plaque formation is widely studied using both experimental and theoretical methods in literature.

Advanced Engineering Materials, EarlyView.This study demonstrates a novel, additive manufacturing approach to produce complex, porous tungsten carbide structures using water‐based direct ink writing/robocasting. Leveraging a modified commercial printer and heat treatment, the process yields lightweight, electrically conductive 3D architectures capable of supporting a mechanical load.

The Effect of Bubbles on Particle Migration in Non-Newtonian Fluids
Separations, 2021 The movement of the gas–liquid interface caused by the movement of the bubble position will have an impact on the starting conditions for particle migration.

Nihon Reoroji Gakkaishi(Journal of the Society of Rheology, Japan), 1982 The present paper summarizes various problems on non-Newtonian fluid mechanics. Due to complex rheological behaviors of non-Newtonian fluids, constitutive equations have highly nonlinear character. As two approaches to obtain constitutive equations, continuum mechanics and molecular theory are described, and then a number of models are presented ...

Advanced Engineering Materials, EarlyView.Laser remelting of a CrMnFeCoNi high‐entropy alloy reveals that optimal chemical homogenization occurs between 30 and 40 J·mm−2. Within this range, elemental segregation is reduced by over 30% compared to the as‐cast state. The study establishes this window as a fast, effective alternative to prolonged annealing for achieving uniform elemental ...
