Slip flow in porous media

Fuel, 2016
Abstract The dynamics of fluids and their interaction with surfaces in Unconventional Gas Reservoirs (UGRs) are very different from those in conventional systems. The physics of flow through the matrices of these reservoirs are not well understood. The small size of flow conduits which is comparable to the gas mean free path results in a deviation ...

Observation of Slip Flow in Thermophoresis

Physical Review Letters, 2008
Two differing theories aim to describe fluidic thermophoresis, the movement of particles along a temperature gradient. While thermodynamic approaches rely on local equilibrium, hydrodynamic descriptions assume a quasi-slip-flow boundary condition at the particle's surface. Evidence for slip flow is presented for the case of thermal gradients exceeding (

Slip flow in graphene nanochannels

The Journal of Chemical Physics, 2011
We investigate the hydrodynamic boundary condition for simple nanofluidic systems such as argon and methane flowing in graphene nanochannels using equilibrium molecular dynamics simulations (EMD) in conjunction with our recently proposed method [J. S. Hansen, B. D. Todd, and P. J. Daivis, Phys. Rev. E 84, 016313 (2011)10.1103/PhysRevE.84.016313].

Slip flow due to a stretching cylinder [PDF]

International Journal of Non-Linear Mechanics, 2011
The slip flow due to a stretching cylinder is studied. A similarity transform reduces the NavierStokes equations to a set of non-linear ordinary differential equations. Asymptotic solutions for large Reynolds number and small slip show the problem can be

Liquid flow in pores: Slip, no-slip, or multilayer sticking

Physical Review A, 1989
The Hagen-Poiseuille flow of a Lennard-Jones liquid through a cylindrical pore formed by regularly arranged fixed atoms is studied by molecular-dynamics (MD) simulations. Different flow patterns develop depending on the strength of the wall-fluid interaction, the strength of the gravitational-type driving force, the thermodynamic state, and also on the

Spectral analysis of the weighted Laplacian in slip and no-slip flows

Physical Review E, 2009
Slip boundary conditions for the velocity field impact on the spectral properties of the advection-diffusion operator describing transport of passive particles in laminar parallel flows. By considering the Hermitian operator (referred to as the weighted Laplacian), describing the interplay between axial convection and cross-sectional diffusion of a ...

Controlling Viscoelastic Flow in Microchannels with Slip

Langmuir, 2011
We show that viscoelastic flow in a microchannel under a dynamic pressure gradient dramatically changes with the value of the apparent slip. We demonstrate this by using classical hydrodynamics and the Navier boundary condition for the apparent slip. At certain driving frequencies, the flow is orders of magnitude different for systems with and without ...

On the analogy in slip flows—II

Applied Scientific Research, 1979
In the present paper two examples of (i) generalized plane Couette flow over a smooth stationary plate and (ii) flow past a smooth solid sphere have been discussed to confirm the analogy in slip flows. It has been shown that the results can directly be carried over to the flow over corresponding naturally permeable surfaces up to the order of

Slip flow on a microcylinder

Zeitschrift für angewandte Mathematik und Physik, 2009
This paper is concerned with uniform axial flow of a gas along a semi-infinite microcylinder in the slip regime. Following Glauert and Lighthill (Proc R Soc 230A:188–203, 1955), the effect of slip on the skin friction is investigated by employing an asymptotic series approach for large axial distances along the cylinder.
