Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.
AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
The distinct element method (DEM) is an approach to modelling and simulation well suited to the study of discontinuous phenomena. By tracking each element individually and dealing explicitly with every interaction among the elements, the DEM allows one to ...
In this paper, the phenomenon of strain localization, i.e., shear banding, in densely distributed metallic assemblies has been studied. A discrete element methodology for analyzing metallic granular materials has been put forward. In this numerical model, ...
The LCI (Load commutated Inverter) is still today a suitable solution for supplying high power variable speed drive systems. The following main topics are described in this contribution: The modeling of a 20 MW LCI synchronous drive system for a compressio ...
An estimate of the rate of increase in numerical simulation grid sizes with time is obtained by counting the grids (measured in terms of number of node points) reported in the nine volumes of an established proceedings on the numerical modeling of solidifi ...
Growing population, extensive use (and abuse) of the natural resources, increasing pollutants emissions in the atmosphere: these are a few obstacles (and not the least) one has to face with nowadays to ensure the sustainability of our planet in general, an ...
A numerical model is presented for the simulation of complex fluid flows with free surfaces. The unknowns are the velocity and pressure fields in the liquid region, together with a function defining the volume fraction of liquid. Although the mathematical ...
The proposed paper describes the modelling and the prediction of the steady- state or transient behaviour of different modern variable-speed drives. The necessity of a performant numerical simulation tool in order to guarantee an optimized design is illust ...
Different measurement techniques have demonstrated that due to better alignment during the manufacturing process, the central filaments in multifilamentary Bi-2223 tapes have higher critical current density than the outer filaments. A numerical model of no ...
The dynamic and efficient usage of the resources is one of the fundamental aspects studied in the DIANA project: at first the traffic specification should reflects the real traffic demand, but, at the same time, optimize the resources requested. In applica ...
This paper presents a numerical simulation of the flow field on a one-dimensional pneumatic actuator. Unlike conventional actuators, this model uses dynamic pressure instead of friction to drive a slider. The objective of this simulation is to know the det ...
