Numerical Simulation of a Class of PDAEs with a Separation of Time Scales

Modeling and simulation of dynamic systems with a separation of time-scales leads naturally to sing ular perturbation models. For systems of PDEs in time and one spatial dimension, the corresponding quasi-steady-state models yields a reduced set of PDEs (s ...

Subtilin Production by Bacillus Subtilis: Stochastic Hybrid Models and Parameter Identification

Giancarlo Ferrari Trecate

This paper presents methods for the parameter identification of a model of subtilin production by Bacillus subtilis. Based on a stochastic hybrid model, identification is split in two subproblems: estimation of the genetic network regulating subtilin produ ...

Flow in a Pelton Turbine Bucket: Numerical and Experimental Investigations

François Avellan, Mohamed Farhat, Alexandre Perrig

The aim of the paper is to present the results of investigations conducted on the free surface flow in a Pelton turbine model bucket. Unsteady numerical simulations, based on the two-phase homogeneous model, are performed together with wall pressure measur ...

Multiresolution particle-based fluids

Mark Pauly

We propose a new fluid control technique that uses scale-dependent force control to preserve small-scale fluid detail. Control particles define local force fields and can be generated automatically from either a physical simulation or a sequence of target ...

Mathematical analysis and numerical simulation of the motion of a glacier

Adrian Reist

A numerical method for the simulation of the motion of a glacier in two and three dimensions is presented. Glacier ice is treated as an incompressible viscous fluid. The model equations are based on mass, momentum, energy conservation and a specific rheolo ...

Mathematical models and numerical simulations for the America's Cup

Alfio Quarteroni, Nicola Parolini

This paper presents a review of the mathematical models which can be adopted to describe the different physical phenomena characterizing the flow around a sailing yacht. The complete model accounting for laminar-turbulent transition regime, free-surface dy ...

Numerical simulation of free surface incompressible liquid flows surrounded by compressible gas

Jacques Rappaz, Marco Picasso, Alexandre Caboussat

A numerical model for the three-dimensional simulation of liquid-gas flows with free surfaces is presented. The incompressible Navier-Stokes equations are assumed to hold in the liquid domain. In the gas domain, the velocity is disregarded, the pressure is ...

On the behavior of spherical and non-spherical grain assemblies, its modeling and numerical simulation

Lionel Pournin

This thesis deals with the numerical modeling and simulation of granular media with large populations of non-spherical particles. Granular media are highly pervasive in nature and play an important role in technology. They are present in fields as diverse ...

Numerical Simulation of Two-Phase Partition Chromatography in Microchannels for Moderated Log P Measurements

Hubert Girault, Pierre-Alain Carrupt

A finite element simulation has been used in order to study the partition chromatography process of one species between an aqueous mobile phase and an organic stationary phase located at the bottom of a rectangular microchannel. The transient model incorpo ...

144Ce as a potential candidate for interstitial and intravascular brachytherapy

Rakesh Chawla, François Bochud

To investigate the suitability of 144Ce for both interstitial and intravascular brachytherapy applications. Monte Carlo calculations of radial dose rate distributions in water were performed for 144Ce in a spring-shaped source and compared with two commonl ...
