Spectral analysis of the weighted Laplacian in slip and no-slip flows
Physical Review E, 2009Slip 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, 2011We 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, 1979In 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

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.

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

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 ...

Planar Stretching Flows with Partial Slip
2013 15th International Symposium on Symbolic and Numeric Algorithms for Scientific Computing, 2013The investigation deals with the slip effects on the problem of viscous incompressible flows induced by a stretching sheet. This problem correspond to the planar stretching. The flow is governed by a third-order nonlinear boundary value problem which has been solved by Optimal Homotopy Asymptotic Method (OHAM).

A solution is presented for the flow of a viscous incompressible fluid in the entrance region of an annulus with slip occurring at the walls. The condition is imposed that the pressure drop found from momentum considerations should be the same as that from mechanical energy considerations.

AbstractSlip flow in ducts occurs in many practical fluid transport situations. The method of eigenfunction expansion and collocation is used to solve the velocity distribution for slip flow in ducts of polygonal, elliptic and cuspidal cross sections. The friction factor‐ Reynolds number products are tabulated.
