Abstract: Les essais ont ete realises en utilisant une surface elastique rigide supporte par un cylindre pres d'une frontiere plane dans un ecoulement constant avec des intensites de turbulence de 3,4, 5,5, et 9,5% de quatre trous de rapports de diametre G/D egaux a 0,5, 0,75, 1,0 et 3,0. Le domaine des nombres de Reynolds bases sur une vitesse moyenne d'ecoulement et un diametre de cylindre etait de 0,65•10 4 a 0.35×10 5

Transverse vortex-induced vibration of spring-supported circular cylinder translating near a plane wall
TL;DR: In this article, the transverse vortex induced vibration of a spring-supported circular cylinder of low mass and zero damping translating near a plane wall at Re = 100 was numerically studied.

TL;DR: The von Karman vortex-street as discussed by the authors is a well-known model for vortex shedding in fluid flows, where the boundary layer vorticity convects aft and coalesces into discrete swirling vortices in the near wake.

Influence of loads in the process of laying on the resource of sea pipelines
TL;DR: In this paper, the effect of pre-operational loads on the resource of marine pipelines was analyzed. But the authors focused on the impact of the pre-construction process on the deformation behavior of the pipeline material.
