Designing a flow-controlled STA-MCA anastomosis based on the Hagen–Poiseuille law for preventing postoperative hyperperfusion in adult moyamoya disease

open access: yesTherapeutic Advances in Chronic Disease, 2023
Background: Technical improvements for preventing postoperative symptomatic cerebral hyperperfusion (CHP) during superficial temporal artery-middle cerebral artery (STA-MCA) anastomosis for moyamoya disease (MMD) were seldom reported. Objectives: The aim

Brownian dynamics simulations on the trapping characteristics of magnetic disk-like particles flowing in a Hagen-Poiseuille flow

open access: yesNihon Kikai Gakkai ronbunshu, 2023
In the present study, we have elucidated the behavior of a suspension composed of magnetic disk-like particles that flow in a Hagen-Poiseuille flow in a gradient magnetic field and the trapping characteristics of the magnetic particles by means of multi ...

Couette–poiseuille flow in semi-elliptic channels

open access: yes, 2022
We present a novel analytical solution for Couette flows of incompressible Newtonian fluids in channels with a semi-elliptical cross section. The flow is steady, unidirectional, satisfies the no-slip condition at the boundaries, and is driven by the ...

Simulation of liquid movement in cylindrical shells

open access: yesВісник Харківського національного університету імені В.Н. Каразіна. Серія: Математичне моделювання, інформаційні технології, автоматизовані системи управління, 2020
The motion of a viscous incompressible fluid with constant coefficients in case of the Hagen-Poiseuille  flow is considered in this paper. The equation of motion of the elastic shell in the absence of external perturbations is obtained on the basis of ...

Electronic Poiseuille flow in hexagonal boron nitride encapsulated graphene field effect transistors

open access: yesPhysical Review Research, 2023
Electron-electron interactions in graphene are sufficiently strong to induce a correlated and momentum-conserving flow such that charge carriers behave similarly to the Hagen-Poiseuille flow of a classical fluid.

Hagen-Poiseuille Flow Linear Instability

open access: yesCardiometry, 2014
In the suggested here linear theory of hydrodynamic instability of the Hagen Poiseuille flow it is counted the possibility of quasi periodic longitudinal variations, when there is no separation of the longitudinal and radial variables in the description of the disturbances field. It is proposed to use the energetic method and the Galerkin approximation

Nonlinear travelling waves in rotating Hagen–Poiseuille flow [PDF]

open access: yesFluid Dynamics Research, 2018
Abstract The dynamics of viscous flow through a rotating pipe is considered. Small-amplitude stability characteristics are obtained by linearizing the Navier–Stokes equations around the base flow and solving the resulting eigenvalue problems.

Development of a Flowmeter for Sub Micro Liter per Second Order Unsteady Flow Rate Based on the Pressure Difference in a Capillary

open access: yesJournal of Fluid Science and Technology, 2008
In order to measure unsteady flow rate of the order of less than 1μl/sec, a new flowmeter consisting of a capillary and a pressure gauge has been developed.

Design of poiseuille flow controllers using the method of inequalities [PDF]

open access: yes, 2009
This paper investigates the use of the method of inequalities (MoI) to design output-feedback compensators for the problem of the control of instabilities in a laminar plane Poiseuille flow.

Significance of Brownian Motion for Nanoparticle and Virus Capture in Nanocellulose-Based Filter Paper

open access: yesMembranes, 2018
Pressure-dependent breakthrough of nanobioparticles in filtration was observed and it was related to depend on both convective forces due to flow and diffusion as a result of Brownian motion.
