Expanding Your Materials Horizons
Materials and their related properties are intrinsically fundamental to the creation, development and solution of viable exploratory models when using numerical analysis software. In many cases, simply determining the location, availability and relative accuracy of the necessary material ... 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
A Study of Lubricating Flows in MEMS Bearings
The bearing and shaft are part of a safe and arm device constructed as an assembly by a multi-layer additive/subtractive plating and planarization processes (EFAB technology). Devices are constructed by a multi-layer additive/subtractive planarization process. This paper evaluates 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
Wireless Interaction of Neighboring Two Arm Archimedes Spiral Coils in the RF Electromagnet Range
The paper addresses a class of problems for modeling and consequently simulating the electromagnetic field radiation pattern from two arms Archimedes spiral coils. The frequency spatial wavelengths relative to the coil dimensions are in a range where the electromagnetic Maxwell’s ... Read More
Finite Element Analysis of an Enzymatic Biofuel Cell: The Orientations of a chip inside a blood artery
Output performance of an implantable enzymatic biofuel cell (EBFC) with three- dimensional highly dense micro-electrode arrays has been simulated with a finite element analysis approach. The purpose of this research is to optimize the orientation of this EBFC chip inside a blood artery ... 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
