Corrugated pipe as a beam dechirper [PDF]
Nuclear Instruments and Methods in Physics Research, Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2012 We have studied the use of a metallic pipe with small corrugations for the purpose of passively dechirping, through its wakefield, a short, intense electron bunch. The corrugated pipe is attractive for this purpose because its wake: (i) has near maximal possible amplitude for a given aperture and (ii) has a relatively large oscillation wave length ...

Journal of the Hydraulics Division, 1976
The detailed measurement and analysis of the turbulent velocity distribution and friction loss data associated with the flow of water in a 100-mm diam corrugated plastic pipe is described. For the roughness geometry adopted, the friction factor - Reynolds number characteristic revealed a distinct peak in the initial stages of transition and fully ...

On the Whistling of Corrugated Pipes With Narrow Cavities
Volume 4: Fluid-Structure Interaction, 2013Pipes with a corrugated inner surface, as used in flexible pipes for gas production and transport, can be subject to Flow-Induced Pulsations when the flow velocities are higher than a certain onset velocity. The onset velocity for classical corrugated pipes can be predicted on basis of the geometry of the corrugations, the operational conditions and ...

On the whistling of corrugated pipes
Journal of fluid mechanics, 2011Whistling behaviour of two geometrically periodic systems, namely corrugated pipes and multiple side branch systems, is investigated both experimentally and numerically. Tests are performed on corrugated pipes with various lengths and cavity geometries.

Viscous Flows in Corrugated Pipes
ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, 1995Analytical solutions describing Stokes flows in a corrugated pipe of a special form and in annular region between such two pipes are obtained using epitrochoid and hypotrochoid conformal mappings. There are two parameters in the mappings: one is the amplitude of the corrugation, and the other is related to the wavelength of the corrugation.
