Measurement of slip length on superhydrophobic surfaces [PDF]
Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2012 In this paper, a review of different techniques used to measure the slip length on superhydrophobic surfaces with large slip length is presented. First, we present the theoretical models used to calculate the effective slip length on superhydrophobic surfaces in different configurations of liquid flow.

The effect of slip variability on earthquake slip-length scaling [PDF]
Geophysical Journal International, 2005 SUMMARY There has been debate on whether average slip D in long ruptures should scale with rupture length L ,o rwith rupture width W . This scaling discussion is equivalent to asking whether average stress drop σ ,w hich is sometimes considered an intrinsic frictional property of af ault, is approximately constant over a wide range of earthquake sizes.

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.

Slip Length Dependent Propulsion Speed of Catalytic Colloidal Swimmers near Walls [PDF]
Physical Review Letters, 2020 Catalytic colloidal swimmers that propel due to self-generated fluid flows exhibit strong affinity for surfaces. We here report experimental measurements of significantly different velocities of such microswimmers in the vicinity of substrates made from different materials.

EFFECTIVE SLIP LENGTH OF NANOSCALE MIXED-SLIP SURFACES [PDF]
The ANZIAM Journal, 2009 AbstractWe present an approximate relation for the effective slip length for flows over mixed-slip surfaces with patterning at the nanoscale, whose minimum slip length is greater than the pattern length scale.

Slip length measurement of gas flow [PDF]
Nanotechnology, 2016 In this paper, we present a review of the most important techniques used to measure the slip length of gas flow on isothermal surfaces. First, we present the famous Millikan experiment and then the rotating cylinder and spinning rotor gauge methods.

The drag reduction mechanism of liquid-infused surface based on lattice boltzmann method
Zhongguo Jianchuan Yanjiu, 2021 ObjectivesNewly proposed in recent years, the liquid-infused surface (LIS) is a drag reduction surface which replaces the residual air conserved by the microgrooves of a traditional superhydrophobic surface with a lubricant, thereby vastly improving the ...
