Anodic Dissolution Model Parameterization for Pulsed Electrochemical Machining Coupled with a Magnetic Field
Manufacture of complex micro-scale parts such as biomedical devices and micro tools that require an excellent surface finish has required non-conventional manufacturing processes such as pulsed electrochemical machining (PECM). Additional reverse polarity pulses make the PECM bipolar ... En savoir plus
Analyzing Electromagnetic Modes of Integrated Busbars Implemented as Printed Circuit Boards (PCB)
This report addresses design of a PCB intended for use as a busbar integrated with multiple DC-link (rail) capacitors in a high power inverter. The geometry and current ratings are typical of a 50 kW unit operating at 60kHz in an intermittent mode. First, circuit aspects are analyzed. ... En savoir plus
Analysis of the Cyclability of Lithium-polymer Batteries
Lithium ion batteries and similar energy storage devices have an increasing importance for the modern society as they are present in many portable electronic devices and have perspectives in the fields of electric vehicles and renewable energy accumulation. Herein, we present results ... En savoir plus
Analysis of D-Shaped Toroidal Superconductive Coils for Medium Size Fusion Experiment Facility
The research in magnetic confinement fusion is carried out through electromagnetic machines, with a toroidal geometry, where a hot plasma of heavy hydrogen isotopes (deuterium and tritium) is contained in a vacuum vessel. Due to the very high temperatures reached by the plasma, strong ... En savoir plus
A Multi-phase Heat Transfer Model of Cooling Lava
Field observations suggest that two-phase "heat-pipe" processes are active around magmatic intrusions. We are numerically testing the viability of this process around a volcanic sill, embedded in wet sediment. The model focuses on the heat transported by water in the vapor and liquid ...

A 3D Simulation of the Diffusion Profile of Brain Derived Neurotrophic Factor in the Inner Ear Using the COMSOL Multiphysics® software
Sensorineural hearing loss, which is the most common type of hearing impairment, originates from damaged inner ear nerves. However, this can be treated in many cases by regenerating the synaptic connections between the extant Spiral Ganglion Neurons (SGNs) and transplanted human stem ... En savoir plus
3D Unsteady CFD Simulation of Seasonal Solar Thermochemical Heat Storage System for Buildings
Solar energy storage has been an extensive research topic among the several thermal energy applications over the past three decades. Thermal energy storage (TES) systems in general, improve the energy efficiency of systems and sustainability of buildings by reducing the mismatch between ... En savoir plus
3D Modeling of Transformation Optics based Flattened Luneburg Lens Using the COMSOL Multiphysics® Software
Three-dimensionally varying flattened Luneburg Lens structure whose axisymmetric invariance of material parameters is calculated by conformal mapping, presents a numerical challenge for three dimensional modelling. To address this problem, conventionally a two dimensional quasi-conformal ... En savoir plus
Using the COMSOL Multiphysics® software for simulation of TEGs for Waste Thermal Energy Harvesting
Navy systems, such as turbine engines, produce large quantities of thermal energy. This energy is a byproduct of the work produced by the engine during operation and is typically rejected to its surroundings. The temperature difference between the turbines and the ocean is substantial ... En savoir plus
Using Multiphysics to Quantify Leakage Rates in New and Rehabilitated Sewer and Water Pipes
Traditionally, municipal sewer and water agencies have relied on acoustic data loggers and closed-circuit television cameras to inspect pipes for leaks. In addition, the same legacy techniques have been used to certify new and rehabilitated pipes as watertight. Unfortunately, visually ... En savoir plus
