Friction Modification by Shifting of Phonon Energy Dissipation in Solid Atoms
Tribology Online, 2015 Numerous researchers have focused on the relation between kinetic friction and the surface properties of materials, such as their surface roughness and chemical state, because kinetic friction is the loss of kinetic energy at a sliding interface ...

Large-eddy simulation of a hypersonic turbulent boundary layer over a compression corner
AIP Advances, 2023 In this paper, large-eddy simulation of the interaction between a shock wave and the hypersonic turbulent boundary layer in a compression corner with a fixed 34° deflection angle at Ma = 6 for different Reynolds number cases is conducted.

Anisotropic Wettability of Bioinspired Surface Characterized by Friction Force
Biomimetics, 2022 Bioinspired surfaces with special wettabilities attract increasing attention due to their extensive applications in many fields. However, the characterizations of surface wettability by contact angle (CA) and sliding angle (SA) have clear drawbacks. Here,

Kinetic Friction of Boardercross-snowboards
Procedia Engineering, 2014 Abstract The purpose of this study was to analyze the kinetic friction of different combinations of snowboard base structures and waxes. On a linear tribometer in a cold lab 3 snowboards with 3 different base structures were first waxed with a training wax. Then the friction coefficient was assessed at 2 m/s, 5 m/s and 8 m/s.
