Multiphase Laminar Flow with More Than Two Phases

W. T. Vetterling [1],
[1] Zink Imaging, Inc., Billerica, MA, USA

Introduction The COMSOL Multiphysics® software and its CFD Module have a physics interface for solving Laminar Two-Phase Flow problems using the Level Set method (1). This paper discusses how the tool may be used with more than two phases when the flow is laminar. It then introduces a ... En savoir plus

Optimal Placement of Piezoelectric Plates to Control Multimode Vibrations of Rotating Beam

F. Botta[1], D. Dini[2], S. Gentili[1], G. Cerri[1]
[1]Dipartimento di Ingegneria Meccanica e Industriale, Università degli Studi di Roma Tre, Roma, Italy
[2]Department of Mechanical Engineering, Imperial College London, London, United Kingdom

Turbomachines blades are forced by a load resulting from the interaction with the fluid. The consequent vibrations, and the associated fatigue phenomena, can give catastrophic failures and the reduction of the blades life. It could be increased if damping system are used. The ... En savoir plus

Analysis Of Linearly Polarized Modes

I. Avram, and I. Gavril Tarnovan
The Technical University of Cluj Napoca
Cluj, Romania

This paper presents a study on the propagation modes of electromagnetic waves through a step index fiber optics. To analyze the propagation of electromagnetic field, a simulation in Comsol 4.0 has been implemented using two different optical fibers. Obtaining the propagation modes, ... En savoir plus

How Apps Can Support COMSOL Multiphysics® Users?

G. Petrone [1], C. Barbagallo [1],
[1] BE CAE & Test, Catania, Italy

Disposing of easy-to-use COMSOL Multiphysics® app to exploit FE-based simulations represents an important opportunity for people working in several industrial areas – from the electronics to the process engineering. In supplying consultancy services, Engineers at BE CAE & Test ... En savoir plus

3D Modeling and Analysis of a Mock-up Ironless Stator Design for Electrical Machines

T. Aravindakshan¹, Dr. P. Masson²
¹Florida Institute of Technology, Melbourne, FL, USA
²AML Superconductivity and Magnetics, Melbourne, FL, USA

With the evolving trend of electrification in transportation, electric machines with higher power density and higher efficiency are demanded which results in the thermal limit of the stator winding becoming more of a key constraint. The achievable current density in stator windings is ... En savoir plus

A Computational Study of Stoichiometry Sensitivity of a PEM Fuel Cell with Multi-Parallel Flow Channels

M. A. Rahman [1], J. M. Mora [2], P. A. Chuang [1],
[1] School of Engineering, University of California, Merced, CA, USA
[2] University of the Philippines - Diliman, Quezon City, Philippines

Flow channel design in a PEM fuel cell plays a critical role for uniformly distributing reactants to the reaction sites and effectively removing product water to prevent flooding. Simplistic design and uniform reactant distribution make parallel channels a potential candidate for ... 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

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

Numerical Simulation of Exact Two-Dimensional Governing Equations for Internal Condensing Flows

S. Mitra, R. Naik, and A. Narain
Michigan Technological University, Houghton, MI, USA

The paper outlines a two-dimensional computational methodology and presents results for laminar/laminar condensing flows inside mm- scale ducts. The methodology has been developed using MATLAB/COMSOL platform and is currently capable of simulating film-wise condensation for steady and ... En savoir plus

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
