The velocity of a liquid slug falling in a capillary tube is lower than predicted for Poiseuille flow due to presence of menisci, whose shapes are determined by the complex interplay of capillary, viscous, and gravitational forces. Due to the presence of menisci, a capillary pressure proportional to surface curvature acts on the slug and streamlines are bent close to the interface, resulting in...

Soft entities can be deformed by Poiseuille flows in thin microfluidic channels. Exploiting this phenomenon, we show that red blood cells exhibit a deformation-induced actuation when being subjected to asymmetric periodic flow fields, whereas rigid beads vanishing net drift.

Diffusion–convection impedance for a micro-band electrode placed in Poiseuille flow was studied experimentally under microfluidic conditions. Electrochemical spectroscopy (EIS) experiments performed with fast electrochemical system show perfect agreement previously published quantitative analytical expression the low frequency domain.

The goal of this work is to look at how heat transfer affects the oscillating flow a hydrodynamically magnetizing Prandtl-Eyring fluid through porous material under impact temperature and concentration two different engineering conditions: Poiseuille Couette flow. To get an unambiguous formula for motion, we utilized perturbation approach. Graphs are used illustrate findings..

We demonstrate that a compact manometer experiment allows direct observation of a delay to the classical electric-field-induced Freedericksz transition produced by flow in a highly dispersive nematic liquid crystal layer. The Ericksen-Leslie equations are used to show that a flow aligning torque generated in the nematic layer under Poiseuille flow competes with the orthogonal electric-field reo...

In this paper, we prove the linear stability of pipe Poiseuille flow for general perturbations at high Reynolds number regime. This has been a long-standing problem since experiments in 1883. Our work lays foundation theoretical analysis hydrodynamic flow, which is one oldest yet unsolved problems fundamental fluid dynamics. © 2022 Wiley Periodicals LLC.
