Critical Nucleation Length for Accelerating Frictional Slip [PDF]
Geophysical Research Letters, 2017 AbstractThe spontaneous nucleation of accelerating slip along slowly driven frictional interfaces is central to a broad range of geophysical, physical, and engineering systems, with particularly far‐reaching implications for earthquake physics. A common approach to this problem associates nucleation with an instability of an expanding creep patch upon ...

A Fractal Permeability Model of Tight Oil Reservoirs Considering the Effects of Multiple Factors
Fractal and Fractional, 2022 The prediction of permeability and the evaluation of tight oil reservoirs are very important to extract tight oil resources. Tight oil reservoirs contain enormous micro/nanopores, in which the fluid flow exhibits micro/nanoscale flow and has a slip ...

High-Velocity Shear and Soft Friction at the Nanometer Scale
Frontiers in Mechanical Engineering, 2021 We study high-speed friction on soft polymer materials by measuring the amplitude dependence of cyclic lateral forces on the atomic force microscope (AFM) tip as it slides on the surface with fixed contact force.

Giant slip length at a supercooled liquid-solid interface
Physical Review E, 2023 The effect of temperature on friction and slip at the liquid-solid interface has attracted attention over the last twenty years, both numerically and experimentally. However, the role of temperature on slip close to the glass transition has been less explored.

Applied Sciences, 2018 Boundary conditions of the liquid–solid interface of micro/nano fluid flow are of great interest, as slippage is linked with decreased drag. However, previous studies have seldom included a systematic analysis of the effect of roughness on the ...

Drag Reduction by Riblets on a Commercial UAV
Applied Sciences, 2022 Riblets are micro-grooves capable of decreasing skin-friction drag, but recent work suggests that additional benefits are possible for other components of aerodynamic drag. The effect of riblets on a fixed-wing, low-speed Unmanned Aerial Vehicle (UAV) on
