Burnett description for plane Poiseuille flow
Physical Review E, 1999 Two recent works have shown that at small Knudsen number (K) the pressure and temperature profiles in plane Poiseuille flow exhibit a different qualitative behavior from the profiles obtained by the Navier-Stokes equations. Tij and Santos [J. Stat. Phys.

Instability Of Plane Poiseuille Flow In A Fluid-Porous System
, 2008 The instability of Poiseuille flow in a fluid-porous system is investigated. The system consists of a fluid layer overlying porous media and is subjected to a horizontal plane Poiseuille flow.

Applied Rheology, 2008 In practice, while placing concrete in a formwork by pumping, the pressure generated by the pump is not controlled. In order to enhance the safety on the worksite, and in view of the current economic and ecologic arguments, it would be useful to dispose ...

Deep Underground Science and Engineering, EarlyView.This study investigates the hydro‐mechanical response and fracture evolution in depleted sandstone reservoirs during CO2 injection, considering both direct wellbore injection and hydraulic‐fracture‐assisted injection. The graphical abstract illustrates how CO2 injection induces dynamic stress redistribution, leading to natural fracture activation ...

Immersed Boundary Projection Method for Boundaries With Slip Velocities
International Journal for Numerical Methods in Fluids, EarlyView.A formulation of the immersed boundary method for incompressible flow over arbitrarily‐shaped bodies with surface slip described by the Navier boundary condition is presented. The wall slip velocity and the boundary force are determined implicitly through a projection to satisfy both the boundary condition and the divergence‐free condition of the ...

Turbulence in Automaton Solution of Poiseuille Flow.
JSME International Journal Series B, 1992 The cellular automaton method, which can generate the Navier-Stokes equation, is utilized for simulating fluid motion numerically. This method has the advantage of examining the statistical property involved in the macroscopic variables, since the elementary process is described by the stochastic process.

Non-modal stability in Hagen-Poiseuille flow of a Bingham fluid
, 2014 Linear stability in Hagen-Poiseuille flow of a Bingham fluid is considered. Bingham fluid exhibits a yield stress in addition to a plastic viscosity. A Bingham number B, which describes the ratio of yield and viscous stresses, is used to characterize the

Simultaneous Image Registration and Monocular Volumetric Reconstruction of a fluid flow [PDF]
, 2011 We propose to combine image registration and volumetric reconstruction from a monocular video of a draining off Hele-Shaw cell filled with water. A Hele-Shaw cell is a tank whose depth is small (e.g. 1 mm) compared to the other dimensions (e.g.

Journal of Magnetic Resonance Imaging, EarlyView.ABSTRACT Background Whether signal intensity (SI) on Silent MRA reflects hemodynamics in brain arteriovenous malformations (BAVMs) is unclear. Objectives To evaluate the relationship between Silent MRA SI and 4D flow‐derived hemodynamic parameters and examine whether Silent MRA‐based metrics are associated with symptomatic hemorrhage in BAVM.
