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 ...
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 ...
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 ...
Electroceramics research is driven by technology and device applications. This growing field includes a vast number of magnetic, dielectric, ionically conducting, semiconducting, and superconducting ceramics used in domains as diverse as transportation, in ...
This paper analyzes by numerical simulation the formation, the fragmentation, and the penetration in a plate of a copper jet that develops in a shaped charge. A finite element Lagrangian code has been used to gain insight into this problem. The study is co ...
Large Eddy simulation (LES) of shock/homogeneous turbulence have been performed at two different Mach numbers (1.2 and 2) with four different subgrid scale (SGS) models (Smagorinsky model, mixed scale model, dynamic Smagorinsky model, dynamic mixed model). ...
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 aim of this study was to provide a complete experimental and numerical analysis of the flow in a rotating Pelton bucket. For the experimental analysis, several functioning points have been used in order to study differences which may occur in various s ...

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 ...
It is well known that a simple binary feedback rate--based congestion avoidance scheme cannot ensure a fairness goal of the Available Bit Rate (ABR) service, namely, max-min fairness. In this paper we show how the rates are distributed for the network cons ...
