Optimization of Dynamic Embedded, Water Based Surface Heat (and Cold) Emitting System for Buildings
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
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
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
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
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
An Agglomerate Model for the Rationalisation of MCFC Cathode Degradation
This paper describes the numerical modeling of a key material-stability issue within the realm of Molten Carbonate Fuel Cells (MCFC). The model describes the morphological and attending electrocatalytic evolution of porous NiO electrodes and is apt to predict electrochemical observables ... Read More
Large Scale 3D Flow Distribution Analysis in HTPEM Fuel Cells
Accurate bipolar-plate and flow-field layout is one crucial task for optimizing fuel cells. These cell components perform several functions, including charge transport or gas and water transport throughout the cell just to name a few. Overall, the design depends on the fuel cell ... Read More
Contactless Excitation of MEMS Resonant Sensors by Electromagnetic Driving
A contactless electromagnetic principle for the excitation of mechanical vibrations in resonant structures has been investigated. The principle relies on no specific magnetic property of the resonator except electrical conductivity and can be adopted for employing the structures as ... Read More
Droplet Generation by Means of a Two-Fluid Probe
This paper presents a simulation of the operation of a new type of droplet generation probe. This probe, consisting of two concentrically-arranged tubings, is immersed in a beaker of cell medium so that oil is pumped through the outer tubing at a pumping speed less than fluid is drawn ... Read More
Control of Rolling Direction for Released Strained Wrinkled Nanomembrane
Strained wrinkled and flat nanomembranes have different bending properties when they are released from the underlying substrate. This is caused by increased bending rigidity of the wrinkled film in one direction. We provide theoretical and numerical analysis of the directional rolling of ... Read More
