The influence of solid-liquid interfacial energy anisotropy on equilibrium shapes, nucleation, triple lines and growth morphologies
Michel Rappaz, Mario Alberto Salgado Ordorica, Jonathan Friedli, Aurèle Mariaux
The anisotropy of the solid-liquid interfacial energy plays a key role during the formation of as-solidified microstructures. Using the xi-vector formalism of Cahn and Hoffman, this contribution presents the effect that anisotropy has on the equilibrium sh ...
Elsevier2010A method to determine the onset voltage of single and arrays of electrospray emitters
This paper reports on an accurate and rapid method to compute the onset voltage for a single or for an array of electrospray emitters with complex geometries and on the correlation of the simulation with experimental data. This method permits the exact det ...

2008A methodology for thermo-economic modeling and optimization of solid oxide fuel cell systems
François Maréchal, Daniel Favrat, Nordahl Autissier, Francesca Palazzi
In the context of stationary power generation, fuel cell-based systems are being foreseen as a valuable alternative to thermodynamic cycle-based power plants, especially in small scale applications. As the technology is not yet established, many aspects of ...
Elsevier2007An analytical, control-oriented state space model for a PEM fuel cell system
If fuel cell technology – with its inherent benefits of high efficiency and low emissions – is to be used in decentralised power sources, in mobile or transportation applications, the systems have to be able to adapt to fast load changes and varying operat ...
EPFL2006PEMFC system efficiency optimisation through model based control strategies
When running a fuel cell system in load following mode, several operating points (i.e. a combination of gas flow rates, pressures, humidities, temperatures and current density) can provide the required net power. Typically, only one of those operating poin ...
2006Thermo-Economic Modelling and Optimisation of Fuel Cell Systems
François Maréchal, Daniel Favrat, Francesca Palazzi
If process modelling is a well known approach to compute the performances of fuel cell systems, the optimal design of systems where the process configuration is not fixed a priori remains an issue. The goal of the presented methodology for integrating and ...
Wiley-Blackwell2005Similarity analysis of the subsurface flow response of hillslopes with complex geometry
The matter of the efficient and parsimonious parameterization of hillslope subsurface flow remains an important issue in catchment hydrological studies (Brutsaert, 1995). Insights into the influence of the shape and hydraulic characteristics of hillslopes ...
