Dynamic characteristics and growth curve of rail corrugation at saturation stage
Nihon Kikai Gakkai ronbunshu, 2021 Rail corrugation, which causes the vibration and the noise, is a phenomenon in which roughness patterns of approximately regular wavelengths are formed on the rail running surface by trains running.

Mechanisms of short pitch rail corrugation
, 2022 Short pitch corrugation is a (quasi-) sinusoidal rail vertical defect on rail surface, and it was first found more than one century ago. The wavelength of short pitch corrugation is 20-80 mm, and its amplitude can be up to 100 µm.

Singing Corrugated Pipes [PDF]
American Journal of Physics, 1974 A corrugated tube open at both ends, with air flowing through the tube, sings notes which depend on the flow velocity and the length of the tube. The notes it sings are the natural harmonics of the tube. A given note will sing when the flow velocity is such that the “bump frequency” (frequency at which the air bumps into the corrugations) equals the ...

Biopolymer Filtration in Corrugated Nanochannels [PDF]
Physical Review Letters, 2014 We examine pressure-driven non-equilibrium transport of linear, circular and star polymers through a nanochannel containing a rectangular pit with full hydrodynamic interactions and thermal fluctuations. We demonstrate that with sufficiently small pressure differences, there is contour length-dependent entropic trapping of the polymer in the pit when ...

Ice Nucleation on a Corrugated Surface [PDF]
Journal of the American Chemical Society, 2018 Heterogeneous ice nucleation is a key process in many environmental and technical fields and is of particular importance in modeling atmospheric behavior and the Earth's climate. Despite an improved understanding of how water binds at solid surfaces, no clear picture has emerged to describe how 3D ice grows from the first water layer, nor what makes a ...
