Detached-eddy simulation of flow around a circular cylinder in ground effect

, 2006
In this study we performed a detached-eddy simulation (DES) of flow around a circular cylinder placed near and parallel to a moving ground, on which no boundary layer developed to interfere with the cylinder.

Fatigue Crack Initiation and Growth in Nanocrystalline Ni at Multiple Length‐Scales

Advanced Engineering Materials, EarlyView.
Overview of miniaturized in situ SEM fatigue setup and resultant fatigue crack growth data for nanocrystalline Ni. The presented study focuses on the analysis of fatigue crack growth rate (FCGR) in focused ion beam‐notched microcantilevers prepared from nanocrystalline (NC) Ni as a model material.

Comparative efficiency testing of a composite hydraulic cylinder

Aviation
The paper points to the increasing use of composite materials in hydraulic components. This entails many benefits, such as weight reduction which is particularly important in aviation. However, new problems arise with the use of new materials.

Influence of Test Temperature and Test Frequency on Fatigue Life of Aluminum Alloy EN AW‐2618A

Advanced Engineering Materials, EarlyView.
The influence of test temperature and test frequency on the fatigue life of EN AW‐2618A is investigated. High‐cycle fatigue tests are performed at different test temperatures and frequencies on the 1000 h/230°C overaged state. Both test parameters reduce fatigue life due to time‐dependent damage mechanisms.

The interaction between flow-induced vibration mechanisms of a square cylinder with varying angles of attack [PDF]

, 2012
This study examines the influence of angle of attack of a square section cylinder on the cylinder’s flow-induced vibration, where the direction of the vibration is transverse to the oncoming flow.

Effectiveness of kerosene/water conveying ternary (Cu–SiO2–Al2O3) nanoparticles flowing in vertical cylinder subjected to a melting phenomenon

Journal of Taibah University for Science
The circulation of ternary nanoparticles (Cu–SiO2–Al2O3) in a vertical cylinder filled with kerosene and water is important for improving the transmission of heat in modern lubricant and cooling technologies.

Cylinder-Cylinder Attraction in Uniform Flow

Natural Science, 2018
Two cylinders in a uniform flow can attract each other when their separation distance is within the zones of the perturbed velocities of the cylinders. Enhanced perturbed velocity between cylinders causes lowered pressure by Bernoulli’s law. If the cylinders touch or the gap is very small, the flow will work to separate the cylinders.

Recycling of NiTi Shape Memory Alloys: Fundamental and Technological Aspects of a Vacuum Induction Melting Processing Route

Advanced Engineering Materials, EarlyView.
The present study investigates recycling of NiTi shape memory alloys via vacuum induction melting. An ingot was synthesized from elemental Ni and Ti and subjected to three subsequent remelting cycles. Remelting increases process durations and impurity levels and adversely affects microstructures and functional properties.
