This paper presents the heat flow model and the experimental test bench developed to optimize a new kind of heating floor. In the first part of the text is described the new kind of high reactivity emitting device for building heating and cooling. The second part illustrates the ... Read More

Modelling of the Hydrogen Diffusion in Martensitic Steel in Contact with H2SO4 Media

J. Bouhattate[1], X. Feaugas[1], and S. Frappart[1][2]
[1]Laboratoire d’Etudes des Matériaux en Milieux Agressifs,
Université de La Rochelle, La Rochelle, France
[2]V&M France, CEV, Aulnoye-Aymeries, France

Hydrogen Embrittlement (HE) is one of the mechanisms responsible for premature failure of structures. In the context of environmental sustainability, it is compelling to improve or conceive new processes and/or new materials capable of reducing fracture induced by HE. We analyzed the ... Read More

Classical Models of the Interface Between an Electrode and an Electrolyte

E. Gongadze[1], S. Petersen[1], U. Beck[2], and U. van Rienen[1]
[1]Institute of General Electrical Engineering, University of Rostock, Rostock, Germany
[2]Institute of Electronic Appliances and Circuits, University of Rostock,
Rostock, Germany

The Electrical Double Layer (EDL) plays a major role in understanding the interface between a charged surface (e.g. an implant) and ionic liquids (e.g. body fluids). The three classical models of the EDL (Helmholtz, Gouy, and Chapman-Stern) are numerically solved for a flat surface ... Read More

COMSOL Multiphysics® as a General Platform for the Simulation of Complex Electrochemical Systems

A. Lavacchi[1]
[1]Department of Chemistry, University of Firenze, Sesto Fiorentino, FI, Italy

Microelectrodes demonstrate that modeling is crucial for understanding the behavior of complex electrochemical systems. The use of the finite element methods in electrochemistry may be of much more general interest for its ability to handle complex geometries. In this context a ... Read More

Current Density Simulations in the Electrodeposition from Ionic Liquids: Effects of the Conductivity

I. Perissi[1], C. Borri[1], S. Caporali[1], and A. Lavacchi[1]
[1]Department of Chemistry, University of Firenze, Sesto Fiorentino, FI, Italy

The overall goal of this work is the use of COMSOL Multiphysics® in the modeling of the current density distributions for the electrodeposition of aluminum coatings from ionic liquids. The local current distribution is strongly dependant on the conductivity and on the geometry of the ... Read More
