Transport Phenomena in Chemical Engineering involves three key aspects: Momentum, Heat and Mass Transport. These areas are described by differential equations which are solved for a particular problem using independent or a set of combined equations (e.g., water flowing in a heated ... En savoir plus
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 ... En savoir plus
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 ...

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 ... En savoir plus
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 ... En savoir plus
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 ... En savoir plus
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 ... En savoir plus
Electronic devices operating at cryogenic temperatures are critical for a wide variety of applications including quantum computing, space, medicine and fundamental research [1]. The design of these devices requires accurate physical modeling of the electric fields, currents, conduction ... En savoir plus
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 ... En savoir plus
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 ... En savoir plus
