Flow and slip transition in nanochannels [PDF]
Physical Review E, 2014 We experimentally investigate the Poiseuille flows in nanochannels. It is found that the flow rate undergoes a transition between two linear regimes as the shear rate is varied. The transition indicates that the nonslip boundary condition is valid at low shear rate.

Change in drag, apparent slip and optimum air layer thickness for laminar flow over an idealised superhydrophobic surface [PDF]
, 2013 Analytic results are derived for the apparent slip length, the change in drag and the optimum air layer thickness of laminar channel and pipe flow over an idealised superhydrophobic surface, i.e. a gas layer of constant thickness retained on a wall.

Blood flow, slip, and viscometry
Biophysical Journal, 1971 The viscosity of blood, measured by the usual viscometers in which slip is not considered, is found to be flow dependent, varying markedly with shear rate, pressure gradient, and vessel diameter in the lower ranges of these factors. The study postulates, on grounds thought reasonable, that slip may be present in blood flow, as a function of the nature ...

Wall slip, shear banding, and instability in the flow of a triblock copolymer micellar solution [PDF]
, 2007 The shear flow of a triblock copolymer micellar solution (PEO--PPO--PEO Pluronic P84 in brine) is investigated using simultaneous rheological and velocity profile measurements in the concentric cylinder geometry.

Nihon Kikai Gakkai ronbunshu, 2020 The water lubrication characteristic of partial water-repellent (slip) type flat thrust bearings was examined. In this bearing, water-repellent (slip) regions and hydrophilic (non-slip) regions were alternately arranged in the slip direction, and the ...

Energies, 2018 Slip boundary has an important influence on fluid flow, which is non-negligible in rock micro-fractures. In this paper, an improved pseudo-potential multi-relaxation-time (MRT) lattice Boltzmann method (LBM), which can achieve a large density ratio, is ...
