Multi-frequency vortex-induced vibrations of a long tensioned beam in linear and exponential shear flows [PDF]
The multi-frequency vortex-induced vibrations of a cylindrical tensioned beam of aspect ratio 200, free to move in the in-line and cross-flow directions within first a linearly and then an exponentially sheared current are investigated by means of direct

Vortex-Induced Vibration Suppression of a Circular Cylinder with Vortex Generators
The vortex-induced vibration is one of the most important factors to make the engineering failure in wind engineering. This paper focuses on the suppression method of vortex-induced vibration that occurs on a circular cylinder fitted with vortex ...

The galloping of a 4:1 rectangular cylinder at Re = 300
The flow-induced vibration (FIV) of a rectangular cylinder with a side ratio of 4 at Re = 300 is numerically investigated by a two-dimensional spectral-element method. The cylinder is constrained to vibrate only in the cross-flow direction.

Reduced-order modelling of vortex-induced vibration of catenary riser
A new reduced-order model capable of analyzing the vortex-induced vibration of catenary riser in the ocean current has been developed. This semi analytical-numerical approach is versatile and allows for a significant reduction in computational effort for

Effects of Damping and Reynolds Number on Vortex-Induced Vibrations [PDF]
Vortex-induced vibrations have been studied experimentally with emphasis on damping and Reynolds number effects. Our system was an elastically-mounted rigid circular cylinder, free to oscillate only transverse to the flow direction, with very low ...

Geometry and dynamics of vortex sheets in 3 dimensions [PDF]
We consider the properties and dynamics of vortex sheets from a geometrical, coordinate-free, perspective. Distribution-valued forms (de Rham currents) are used to represent the fluid velocity and vorticity due to the vortex sheets. The smooth velocities

Current Status and Challenges in Data Collection for Aerospace Coatings Deposited by Plasma Spraying
An innovative approach has been integrated into the GRENAT project to optimize plasma spraying and coating performance. Raw materials are accelerated and melted in the plasma generated by torches, creating coatings. Monitoring sensors collect process data which are combined with ex situ characterization data.
