This project modeled an industrial chromium plating process for automotive components. The process was modeled via the COMSOL Multiphysics® Electrodeposition Module. The simulation examined the effect of solution conductivity, electrode spacing, and anode height utilizing a factorial ... En savoir plus
Galvanic corrosion is encountered in marine applications because one often has dissimilar metal joints and seawater acts as an electrolyte. One metal acts predominantly as anode and undergoes material dissolution while the other acts predominantly as cathode and is the site where a ... En savoir plus
A characteristic feature of nanochannels is that surface properties (e.g., electrical charge) play a more significant role in the transport of fluid and electrolyte. Two oppositely directed flows (electroosmotic flow and pressure-driven flow) determine the flow profile at the nanopore ... En savoir plus
The reciprocating paddle cell is a known practical method for depositing alloy films on wafer substrates. Recently, the mass transfer boundary layer within an industrial wafer plating cell was studied based on the measurement of limiting current. It was indicated that a shear-plate fluid ...

Proton exchange membrane fuel cells (PEMFCs) were investigated using COMSOL Multiphysics with the AC/DC Module and Chemical Engineering Module. Simulation may be used to increase the performance while decreasing the cost of the catalyst later (CL). Experimental validation of single and ... En savoir plus
We present a novel multi-layered electrode fabrication technique for polymer electrolyte membrane fuel cells (PEMFCs). This method consists of alternate layers of Pt deposition (0.05 mg/cm²) by sputtering on the painted multi-walled carbon-Nafion layer (CNL) with larger concentration of ... En savoir plus
A 2D isothermal axisymmetric model of an anode-supported Solid Oxide Fuel Cell (SOFC) has been developed. Also a parametric analysis to find the effect of important parameters on the cell performance has been done. This simulation has been carried out at 1 atm and 1073 K. The PEN ... En savoir plus
This paper discusses the simulation studies on a vibration based energy harvesting system to convert the undesirable mechanical vibration to useful green power. The design consists of a resonating proof mass and a spring system enclosed in housing and fixed on the source of vibration. A ... En savoir plus
Low cost high energy density batteries that can be charged and discharged rapidly are required in a number of applications. Tapping energy from renewal resources such as solar, wind and tide requires rapidly generated energy to be first stored and then used round the clock. Storing ... En savoir plus
The Pulse Electrochemical Machining is especially suitable for the precise production of complex geometric contours with high precision and high surface quality demands in workpieces in series manufacturing. During this process, the negative structure of an electrode is copied to the ... En savoir plus
