The Thermal Unbalance Effect Induced by a Journal Bearing in Rigid and Flexible Rotors: Experimental Analysis
Thibaud Plantegenet, Mihai Arghir, Mohamed-Amine Hassini +1
The present work presents the experimental analyses of a rigid (short) and a flexible (long) rotor subject to thermal unbalance effects. The rotors are supported by a ball bearing…
Mathematical and numerical study of a model for navigation in stratified waters
Zeina Rammal, Matthieu Brachet, Germain Rousseaux +1
We derive a linear model of navigation in a two-layer fluid with a variable velocity of the ship. A spectral version of the model including a Rayleigh damping term is analyzed. We…
Transient thermo-elasto-hydrodynamic study of herringbone-grooved mechanical face seal during start-up stage
Yongfan Li, Muming Hao, Noël Brunetière +3
A comprehensive numerical solution is developed for the transient thermo-elasto-hydrodynamic (TEHD) characteristics of mechanical face seals. Transient lubrication features of the…
Evidence of Energy Injection in the Short and Distant GRB 250221A in a High Density Environment
Camila Angulo-Valdez, Rosa L. Becerra, Ramandeep Gill +29
We present the photometric and spectroscopic analysis of the short-duration GRB 250221A ( s), using a data set from the optical facilities COLIBRÍ, the Harlingt…
VIVALDy: A Hybrid Generative Reduced-Order Model for Turbulent Flows, Applied to Vortex-Induced Vibrations
Niccolò Tonioni, Lionel Agostini, Franck Kerhervé +2
Developing reduced-order models applicable to fluid-dynamics problems involving complex geometries and different flow conditions remains a critical challenge for turbulent flows. T…
Parametric pair production of collective excitations in a Bose-Einstein condensate
Victor Gondret, Rui Dias, Clothilde Lamirault +7
By exciting the transverse breathing mode of an elongated Bose-Einstein condensate, we parametrically produce longitudinal collective excitations in a pairwise manner. This process…
