Design of a Flexure-Based Flywheel for the Storage of Angular Momentum and Kinetic Energy
Simon Nessim Henein, Florent Cosandier, Hubert Pierre-Marie Benoît Schneegans, Patrick Robert Flückiger
The flywheel is a widespread mechanical component used for the storage of kinetic energy and angular momentum. It typically consists of cylindrical inertia rotating about its axis on rolling bearings, which involves undesired friction, lubrication, and wea ...
2024On A Special Symmetry In The Dynamics Of Complex Systems In A Holographic-Type Perspective
By operating with the Scale Relativity Theory in the dynamics of complex systems, we can achieve a description of these complex systems through a holographic-type perspective. Then, gauge invariances of a Riccati-type become functional in complex system dy ...
UNIV POLITEHNICA BUCHAREST, SCI BULL2023Morphology and Transport Characterization of Catalyst Layers for CO2 Reduction
Sophia Haussener, Francesca Lorenzutti
Gas diffusion electrodes (GDEs) help to reduce transport limitations in devices for electrochemical CO2 reduction. Homogenized modeling of such devices requires input of morphological characteristics and effective transport properties of the porous structu ...
2023A mathematical theory for mass lumping and its generalization with applications to isogeometric analysis
Annalisa Buffa, Espen Sande, Yannis Dirk Voet
Explicit time integration schemes coupled with Galerkin discretizations of time-dependent partial differential equations require solving a linear system with the mass matrix at each time step. For applications in structural dynamics, the solution of the li ...
2022Planar Equilibria of an Elastic Rod Wrapped Around a Circular Capstan
We present a study on planar equilibria of a terminally loaded elastic rod wrapped around a rigid circular capstan. Both frictionless and frictional contact between the rod and the capstan are considered. We identify three cases of frictionless contact - n ...
SPRINGER2022On predicting pore fluid pressure changes in unsaturated porous media subject to undrained processes
Lyesse Laloui, Alessio Ferrari, Angelica Tuttolomondo
Predicting the induced change of fluid pressure in an unsaturated porous medium during undrained loading/unloading processes is challenging because two different fluids (a liquid and a gaseous solution) and a mixture of solid particles are involved. The re ...
