Understanding the Transition Flow Region through Modeling in COMSOL Multiphysics® Software

J. Sturnfield [1],
[1] Dow Chemical, Freeport, TX, USA

The pore sizes of many membranes being studied for separating the components in gas mixtures are on the scale of nanometers. Depending on the specific gases and pressures being used, this scale will put the flows in the Transition between Slip Flow and Knudsen regime. The differential ... Read More

Multiphysics Model for Breakup of Charged Liquid Droplets in Electric Fields

S. Chaudhuri [1], W. Du [1],
[1] University of Illinois at Urbana-Champaign, Champaign, IL, USA

Predicting and controlling the formation of droplets from a liquid jet is a critical problem in a variety of applications ranging from fuel injection to paint sprays. It is known that liquid droplets subjected to an electric field acquire a net electrostatic charge via induction, and ... Read More

Cycling-Induced Degradation of Batteries

M. Vallance [1], A. Meshkov [1], R. White [2], M. Guo [2], S. Rayman [2], L. Cai [2]
[1] GE Global Research, Niskayuna, NY, USA
[2] R.E. White & Associates, Columbia, SC, USA

Rechargeable batteries solve electrification and communication problems. As examples, hybrid battery-diesel generator power supplies efficiently power cell towers in remote locations, detached from the power grid. Large battery banks are used to load level user power requirements, ... Read More

Acoustic Streaming Driven Mixing

N. Nama [1], P. Huang [1], F. Costanzo [1], T. J. Huang [1]
[1] Department of Engineering Science and Mechanics, Pennsylvania State University, PA, USA

Introduction - The ability to achieve rapid and homogeneous mixing at microscales is one of the essential requirements for various lab-on-a-chip applications [1]. The flow at microscales is characterized by low Reynolds number, resulting in laminar flow patterns. Thus, the mixing at ... Read More

Simulating Corrosion in a Crevice of Commercial Pure Titanium

G. Zhang [1, 2, 3],
[1] Department of Bioengineering, Clemson University, Clemson, SC, USA
[2] Department of Electrical and Computer Engineering, Clemson, SC, USA
[3] Institute for Biological Interfaces of Engineering, Clemson University, Clemson, SC, USA

Implant devices are assistive devices surgically placed in the human body to restore the functionality of organs and tissues. Metallic implants are often used for load bearing applications including the hip and knee joints. To allow maximum flexibility during surgery for surgeons to pick ... Read More

The Effects of the Contact Angle on the Dynamics of Water Droplet Impingement

J. Hu [1], X. Huang [2], X. Xiong [1], K. T. Wan [2],
[1] University of Bridgeport, Bridgeport, CT, USA
[2] Northeastern University, Boston, MA, USA

INTRODUCTION The dynamic behavior of droplet impingement on a solid surface is important to many engineering applications, such as rain drops on automobile windshields, inkjet deposition and metal deposition in manufacturing processes, spray cooling of electronics, and spray coating for ...

Simulation of the Impedance Response of Materials with More Than One Electrical Path

R. A. Gerhardt [1], Y. Jin [1],
[1] Georgia Institute of Technology, Atlanta, GA, USA

Introduction Polycrystalline single phase materials often display electrical properties that are a function of their grain size. Impedance spectroscopy, an alternating current technique is ideal for detecting the presence of more than one current path and has been used for many years ... Read More

Simulation of Spiral-Tube Heat Exchangers in COMSOL Multiphysics® Software

K. O. Lund [1], S. M. Lord [2],
[1] Kurt Lund Consulting (COMSOL Certified Consultant), Del Mar, CA, USA
[2] SML Associates, Encinitas, CA, USA

A frequently occurring geometry for heat exchangers is that of a long tube wound into a helix or spiral around a core volume. There is to be heat exchange between the tube and the gases (or solids) in the core. However, the length scales of these two parts of the geometry are very ... Read More

Transport Phenomena in the Conversion of an Anaerobic Landfill into an Aerobic Landfill

H. Omar [1], S. Rohani [1],
[1] University of Western Ontario, London, ON, Canada

The world’s landfills are beginning to fill up due to the growing human population. Landfills require land and there will come a time when there will be no land to be used for landfills. A solution that is gaining attraction is the conversion of traditional “dry-tomb” landfills (used for ... Read More

A Flow and Transport Model in Porous Media for Microbial Enhanced Oil Recovery Studies Using COMSOL Multiphysics® Software

M. A. Diaz-Viera [1], A. Ortiz-Tapia [1],
[1] Mexican Petroleum Institute, Mexico City, Mexico

A flow and transport model in porous media was implemented in COMSOL Multiphysics® software to simulate, analyze and interpret Microbial Enhanced Oil Recovery (MEOR) processes at core scale under laboratory conditions. The flow model is biphasic and is based on the oil phase pressure ... Read More
