Particle Focusing in a Straight Microchannel with Non-Rectangular Cross-Section

open access: yesMicromachines, 2022
Recently, studies on particle behavior under Newtonian and non-Newtonian fluids in microchannel have attracted considerable attention because particles and cells of interest can be manipulated and separated from biological samples without any external ...

Two-dimensional flagellar synchronization in viscoelastic fluids [PDF]

open access: yes, 2009
Experimental studies have demonstrated that spermatozoa synchronize their flagella when swimming in close proximity. In a Newtonian fluid, it was shown theoretically that such synchronization arises passively due to hydrodynamic forces between the two ...

Computational Predictions for Boger Fluids and Circular Contraction Flow under Various Aspect Ratios

open access: yesFluids, 2020
This work puts forward a modeling study contrasted against experimental, with focus on abrupt circular contraction flow of two highly-elastic constant shear-viscosity Boger fluids, i.e., a polyacrylamide dissolved in corn-syrup PAA/CS (Fluid-1) and a ...

The Newtonian Limit for Perfect Fluids [PDF]

open access: yesCommunications in Mathematical Physics, 2007
We prove that there exists a class of non-stationary solutions to the Einstein-Euler equations which have a Newtonian limit. The proof of this result is based on a symmetric hyperbolic formulation of the Einstein-Euler equations which contains a singular parameter $\ep = v_T/c$ where $v_T$ is a characteristic velocity scale associated with the fluid ...

General Relativistic Effects on Nonlinear Power Spectra [PDF]

open access: yes, 2010
The nonlinear nature of Einstein’s equation introduces genuine relativistic higher order corrections to the usual Newtonian fluid equations describing the evolution of cosmological perturbations.

Investigation of Non-Newtonian Characteristics of Water Flow in Micro-/Nanochannels and Tight Reservoirs

open access: yesGeofluids, 2022
The characteristic scale of pore flow in tight reservoirs is generally in the range of 0.1 μm to 1 μm, which shows the obvious micro- and nanoscale effect.

Numerical Solution of Non-Newtonian Fluid Flow Due to Rotatory Rigid Disk

open access: yesSymmetry, 2019
In this article, the non-Newtonian fluid model named Casson fluid is considered. The semi-infinite domain of disk is fitted out with magnetized Casson liquid.

Polymeric filament thinning and breakup in microchannels [PDF]

open access: yes, 2007
The effects of elasticity on filament thinning and breakup are investigated in microchannel cross flow. When a viscous solution is stretched by an external immiscible fluid, a low 100 ppm polymer concentration strongly affects the breakup process ...

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 ...
