THEORETICAL STUDY ON THE CRASHWORTHINESS OF CORRUGATED TUBE
Jixie qiangdu, 2015 The energy absorbing property of corrugated tube subjected to axial crushing was researched through theoretical analysis. In view of the energy absorbing mechanism for axisymmetric deformation mode,a calculation formula for the mean crush load was put ...

Study on Behavior of the Heat Exchanger with Conically-Corrugated Tubes and HDD Baffles
ChemEngineering, 2022 Baffles with holes in different diameters (or HDD baffles) and conically-corrugated tubes are respectively longitudinal flow baffle and high-efficiency heat exchange tubes proposed by the author. In this paper, vibrations of tube bundles with HDD baffles

Aeroacoustics of the swinging corrugated tube: Voice of the Dragon [PDF]
The Journal of the Acoustical Society of America, 2012 When one swings a short corrugated pipe segment around one’s head, it produces a musically interesting whistling sound. As a musical toy it is called a “Hummer” and as a musical instrument, the “Voice of the Dragon.” The fluid dynamics aspects of the instrument are addressed, corresponding to the sound generation mechanism.

Unbiased diffusion in tubes with corrugated walls [PDF]
The Journal of Chemical Physics, 2010 This study is devoted to unbiased motion of a point Brownian particle in a tube with corrugated walls made of conical sections of a varying length. Effective one-dimensional description in terms of the generalized Fick-Jacobs equation is used to derive a formula which gives the effective diffusion coefficient of the particle as a function of the ...

Biased Brownian motion in extremely corrugated tubes [PDF]
Chaos: An Interdisciplinary Journal of Nonlinear Science, 2011 Biased Brownian motion of point-size particles in a three-dimensional tube with varying cross-section is investigated. In the fashion of our recent work, Martens et al. [Phys. Rev. E 83, 051135 (2011)] we employ an asymptotic analysis to the stationary probability density in a geometric parameter of the tube geometry.
