Pedicle Length and Degree of Slip in Lumbosacral Isthmic Spondylolisthesis [PDF]
Orthopaedic Surgery, 2015 ObjectiveThe present retrospective study was performed to assess the anatomical features of the pedicle in isthmic spondylolisthesis and to correlate this with degree of slip.MethodsTwenty‐six patients with isthmic spondylolytic spondylolisthesis were studied.

Local Flow Field and Slip Length of Superhydrophobic Surfaces [PDF]
Physical Review Letters, 2016 While the global slippage of water past superhydrophobic surfaces has attracted wide interest, the local distribution of slip still remains unclear. Using fluorescence correlation spectroscopy, we performed detailed measurements of the local flow field and slip length for water in the Cassie state on a microstructured superhydrophobic surface.

Electroviscous effect on fluid drag in a microchannel with large zeta potential
Beilstein Journal of Nanotechnology, 2015 The electroviscous effect has been widely studied to investigate the effect of surface charge-induced electric double layers (EDL) on the pressure-driven flow in a micro/nano channel.

Lubrication Models with Small to Large Slip Lengths
Journal of Engineering Mathematics, 2005 A set of lubrication models for the thin film flow of incompressible fluids on solid substrates is derived and studied.The models are obtained as asymptotic limits of the Navier-Stokes equations with the Navier-slip boundary condition for different orders of magnitude for the slip-length parameter.

Study on the drag reduction mechanism of spheres with various hydrophobic types
Comptes Rendus. Mécanique, 2022 In this paper, a 3D hydrophobic model was developed using User-Defined Functions to investigate the flow characteristics and drag reduction mechanism of spheres with various hydrophobic types. The results confirmed that for the fully hydrophobic spheres,

Equilibrium measurement method of slip length based on fluctuating hydrodynamics [PDF]
Physical Review E, 2020 We perform equilibrium molecular dynamics simulations for nanoscale fluids confined between two parallel walls and investigate how the autocorrelation function of force acting on one wall is related to the slip length. We demonstrate that for atomically smooth surfaces, the autocorrelation function is accurately described by linearized fluctuating ...
