[1] Department of Mechanical Engineering, Alexandria University, Alexandria, Egypt

For the commercialization of membraneless microfluidic fuel cell, voltage and minimum power demand for various applications need a precise selection of fuel and oxidant flow rates to achieve the optimum cell performance. A numerical study on a membraneless microfluidic fuel cell was made ... Mehr lesen

3D Printed Microfluidic Medical Devices: Rapid Prototyping Using LiveLink™ for MATLAB®

A. P. Spann [1], M. J. Hancock [1],
[1] Veryst Engineering LLC., Needham, MA, USA

Recent advances in additive manufacturing enable rapid production of low-cost custom devices.[1-2] Despite modern 3D printers apparent resolutions on the order of tens of microns, for microfluidic applications there are challenges associated with the creation of channels below a few ... Mehr lesen

Accelerated Electrochemical Machining Tool Design

[1] Faraday Technology, Inc., Clayton, OH, USA
[2] University of Nebraska, Lincoln, NE, USA

Electrochemical machining (ECM) is a manufacturing technology that allows metal to be precisely removed by electrochemical oxidation and dissolution into an electrolyte solution. ECM is suited for machining parts fabricated from “difficult to cut” materials and/or parts with complicated ... Mehr lesen

Simulation of a Vortex Ring: Dealing with the Unbounded, Doubly Connected Domain

J. M. Russell [1],
[1] Emeritus Professor, Florida Institute of Technology, Melbourne, FL, USA

This talk is for intermediate-level users of COMSOL who, like the present author, are relative newcomers to numerical simulation but have a strong grounding in Hydrodynamics or related areas of Mathematical Physics. Most turn-key Computational Fluid Dynamics packages, including COMSOL ... Mehr lesen

Electromagnetic Modeling of Field Emitter Cathodes Inside an L-Band RF Gun at Fermilab Using COMSOL®

H. Panuganti [1,2,3], P. Piot [1,3],
[1] Northern Illinois Center for Accelerator and Detector Development (NICADD), Northern Illinois University, DeKalb, IL USA
[2] Department of Mechanical Engineering, Northern Illinois University, DeKalb, IL, USA
[3] Fermi National Accelerator Laboratory (FNAL), Batavia, IL, USA

Field-emitter (FE) electron sources offer significant advantages over photocathode and thermionic sources due to their ability to be operated without the need for an auxiliary laser system or a heating source. While FE cathodes have been traditionally used in DC environments, we explore ... Mehr lesen

Numerical Modeling of Resistive Switching in a RRAM Device

D. Niraula [1], V. Karpov [1],
[1] University of Toledo, Toledo, OH, USA

A new nonvolatile memory device based on its resistance state has emerged known as resistive random access memory (RRAM). It operates by switching between the high resistance and low resistance states which can be interpreted as logical 0 and 1 variables. Understanding the resistive ... Mehr lesen

[1] University of Calgary, Calgary, AB, Canada

COMSOL Multiphysics® is used to simulate electric currents in pore-level unconsolidated and consolidated packings of spherical grains. In a nutshell 1) Predefined particle size distribution curves and porosities are used to reconstruct unconsolidated packings; 2) A modified image ... Mehr lesen

Multiphysics Modeling of the Graphite Electrode Joint in Electric Arc Furnaces for Steel Recycling

N. May [1], M. Waldner [2],
[1] GrafTech International Holdings, Inc., Independence, OH, USA
[2] Case Western Reserve University, Cleveland, OH, USA

Electric Arc Furnaces (EAF) use graphite electrodes to strike an arc to melt scrap steel, recycling it for further use. These graphite electrodes oxidize and are consumed over time. To maintain operation new electrodes are attached to others via a joint of complex geometry and fed ... Mehr lesen
