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 ...

International 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 Hydrodynamics of Non-Newtonian Fluids. II [PDF]
Mathematical Proceedings of the Cambridge Philosophical Society, 1948 In this paper, the general hydrodynamic theory of visco-inelastic, incompressible, non-Newtonian fluids, developed in a previous paper (l), is applied to the problem of the flow of such a fluid through a tube of circular cross-section. It is found that the absolute values of the normal stress components are no longer uniform over a cross-section of the

Rheology of waxy oils: A critical review
Applications in Engineering ScienceWaxy oil is a rheologically complex material presenting shear-rate-dependent viscosity, static and dynamic yield stresses, gel elasto-viscoplasticity, time/deformation-dependent gel structure, and irreversibility.

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.

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 ...

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

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 ...
