Time-resolved measurement of quadrupole wakefields in corrugated structures

Physical Review Accelerators and Beams, 2016
Corrugated structures have recently been widely used for manipulating electron beam longitudinal phase space and for producing THz radiation. Here we report on time-resolved measurements of the quadrupole wakefields in planar corrugated structures. It is

Effects of fin corrugation and tube geometry on the airside performance of fin-and-tube heat exchangers - Part I; dry surface

Journal of Thermal Science and Technology, 2021
For a cooling or heating coil of a building air conditioning system, large diameter tubes (over 12.7 mm) with wave fins are frequently used. Furthermore, there have been attempts to apply oval tubes to the heating or cooling coils.

Analysis of the influence of corrugated steel thickness on the damage characteristics and explosion resistance of corrugated steel-concrete composite structure

Case Studies in Construction Materials, 2023
A three-dimensional refined numerical simulation model of corrugated steel-concrete slab composite structure under contact explosion load was established by using FEM-SPH coupling method to explore the anti-explosion performance of corrugated steel ...

A Comparison of Two Artificial Intelligence Approaches for Corrugated Board Type Classification

Engineering Proceedings, 2023
Corrugated board is an environmentally friendly, commonly used packing material. Its basic structure consists of two liners and a flute between them. The mechanical properties and strength of the corrugated board depend not only on the constituent papers

An experimental investigation on the airside performance of fin-and-tube heat exchangers having corrugated louver fins - Part I; dry surface

Journal of Thermal Science and Technology, 2020
Corrugated louver fin, which has louvers on wavy surface, may be a promising mean to augment the air-side heat transfer of fin-and-tube heat exchangers. However, only limited prior studies are available.

Analysis of energy absorption characteristics of corrugated top beams of anti-impact hydraulic supports

Alexandria Engineering Journal, 2022
To enhance the inferior energy-absorption performance of a hydraulic support during coal mine rock burst, which leads to failure and damage, a framework including a kind of corrugated laminated energy-absorbing component on the top beam of the hydraulic ...

Corrugation of roads [PDF]

Physica A: Statistical Mechanics and its Applications, 2001
We present a one dimensional model for the development of corrugations in roads subjected to compressive forces from a flux of cars. The cars are modeled as damped harmonic oscillators translating with constant horizontal velocity across the surface, and the road surface is subject to diffusive relaxation.

An experimental investigation on the airside performance of fin-and-tube heat exchangers having corrugated louver fins - Part II; wet surface

Journal of Thermal Science and Technology, 2020
In this study, two kinds of corrugated louver fin-and-tube heat exchangers – one having one corrugation per row and the other having two corrugations per row – were tested under wet condition, and the results were compared with those of the standard ...
