Effect of Substrate Contact Angle on Ink Transfer in Flexographic Printing

F. E. Hizir[1], D. E. Hardt[1]
[1]Massachusetts Institute of Technology, Cambridge, MA, USA

Flexography is a roll-based mass printing process used in manufacture of printed products such as sensors, self-cleaning surfaces, and flexible electronics. Flexography involves inking of a stamp wrapped around a roller, and the transfer of ink on the stamp surface to a printing ... En savoir plus

Simulation of Interaction of Low-Temperature Plasma with Immersed Solids

V. Hrubý, and R. Hrach
Department of Surface and Plasma Science, Charles University, Prague, Czech Republic

The computer simulation with COMSOL Multiphysics has become a widely used technique for the study of various problems in the field of plasma physics. Despite the increasing performance of computers, fully three-dimensional particle simulations still have got extremely high demands on ... En savoir plus

Reacting Flows in Industrial Duct-burners of a Heat Recovery Steam Generator

G. Petrone[1], G. Cammarata[1], S. Caggia[2], and M. Anastasi[2]
[1]Department of Industrial and Mechanical Engineering, University of Catania, Catania, Italy
[2]Engineering Maintenance - ISAB Energy Services, Priolo Gargallo, Italy

In this study, COMSOL Multiphysics is applied in order to simulate reacting flows for duct burner systems arranged in the post-firing section of a Heat Recovery Steam Generator of a combined cycle power plant. Two- and three-dimensional simulations are carried out in order to ... En savoir plus

Planar Geometry Ferrofluid Flows in Spatially Uniform Sinusoidally Time-Varying Magnetic Fields

S. Khushrushahi, A. Weddemann, Y. Kim, and M. Zahn
Massachusetts Institute of Technology
Cambridge, MA

Prior work has analyzed the case of planar Poiseuille ferrofluid flows in planar ducts stressed by uniform sinusoidally applied fields transverse and perpendicular to the duct axis. The coupled linear and angular momentum conservation equations with imposed magnetic flux density, Bx and ... En savoir plus

Exploratory FEM-Based Multiphysics Oxygen Transport and Cell Viability Models for Isolated Pancreatic Islets

P. Buchwald
Diabetes Research Institute and the Department of Molecular and Cellular Pharmacology, University of Miami, Miller School of Medicine, Miami, FL, USA

Cellular-level oxygen consumption and cell viability models incorporating physiologically realistic assumptions and fully scaled 2D/3D geometries have been implemented in COMSOL Multiphysics for isolated pancreatic islets. Oxygen consumption was assumed to follow Michaelis-Menten–type ... En savoir plus

Design of Passive Micromixers using the COMSOL Multiphysics software package

M. Itomlenskis, P. Fodor, and M. Kaufman

Physics Department, Cleveland State University, Cleveland, OH, USA

Relief patterning of the surface of microchannels has been actively pursued as a method of promoting mixing in systems with a low Reynold’s number (<<100). In this work, we explore, by using the COMSOL Multiphysics package and its Chemical Engineering Module, the possibility of ... En savoir plus

The Use of CFD Simulations in Learning Fluid Mechanics at the Undergraduate Level

Marc K. Smith
Professor of Mechanical Engineering, Georgia Institute of Technology

Simple, accurate CFD simulations using COMSOL Multiphysics are used in a senior-level undergraduate course as a means to explore a number of fluid flows with the intent of developing a deep understanding of the underlying fluid mechanical mechanisms involved in the flows. Students also ... En savoir plus

Space Charge Compensation of Negative Ion Beams

M.Cavenago[1], and P. Veltri[2]
[1]INFN-LNL, Legnaro, PD, Italy
[2]Consorzio RFX, Padova, Italy

Neutral Beam Injectors for ITER require development of negative ion sources and beams with carefully reduced beam divergence. In the accelerator this is compensated by the focusing due to the fringe effect of the electric field, while in the drift region, where the beam is propagating ... En savoir plus

Modeling of Transport Phenomena in Gas Tungsten Arc Welding of Ni to 304 Stainless Steel

A. Bahrami[1], D. K. Aidun[1]
[1]MAE Department, Clarkson University, Potsdam, NY, USA

COMSOL Multiphysics® is used to simulate the transport phenomena in arc welding of Nickel to 304SS. Electric Currents (ec) and Magnetic Fields (mf) are used to solve for the Lorentz force which is one of the volume forces. Laminar Flow (spf) is used to simulate flow field. The Lorentz ...
