Trapping DNA Molecules in Fluids Using Electrokinetic Effects Generated by Different Electrode Geometries

S. Ghonge[1], S. Kapur [1], S. Banerjee[1]
[1]Birla Institute of Technology and Science, Pilani - Hyderabad Campus, Hyderabad, Telangana, India

In this paper we present results of simulations done to predict the behavior of a system consisting of DNA molecules in an aqueous medium under the combined effect of AC Electroosmosis and Dielectrophoresis (DEP). ACEO is caused by the movement of fluid particles under the influence of ... En savoir plus

COMSOL Multiphysics® Models Combined with Experiments to Teach PID Controller Tuning

W. Clark[1]
[1]Chemical Engineering Department, Worcester Polytechnic Institute, Worcester, MA, USA

A laboratory exercise to learn PID controller tuning can be time consuming and taxing on the equipment. A purely equation-based, virtual controller tuning exercise might not seem relevant to real world processes. We have combined a physical process with a COMSOL Multiphysics model to ...

Thermal Study of Valve Regulated Lead Acid Batteries and Electronics Chamber Used in Stand-Alone Street Lighting Applications

D. Groulx[1], J. Skaalum[1], T. Jamieson[1]
[1]Mechanical Engineering, Dalhousie University, Halifax, NS, Canada

This paper presents a study on the heat generation of Valve-Regulated Lead Acid (VRLA) batteries used in off-grid streetlighting applications from PoleCo, a Halifax based company. One goal of the project was to produce validated COMSOL® models of the enclosure that holds these VRLA ... En savoir plus

Finite Element Modeling for Inspection of CANDU® Steam Generators

S. G. Mokros[1], P. R. Underhill[2], J. Morelli[1], T. W. Krause[2]
[1]Department of Physics, Engineering Physics & Astronomy, Queen's University, Kingston, ON, Canada
[2]Department of Physics, Royal Military College of Canada, Kingston, ON, Canada

Steam generators (SGs) are used in CANDU® nuclear reactors as heat exchangers to convert water into steam using heat generated in the reactor core. Ferrous trefoil broach support structures prevent excessive vibration of thousands of SG tubes. A probe that uses pulsed eddy current (PEC) ... En savoir plus

CFD Modeling and Analysis of a Planar Anode Supported Intermediate Temperature Solid Oxide Fuel Cell

N. Lemcoff[1], M. Tweedie[2]
[1]Rensselaer Polytechnic Institute Hartford, Hartford, CT, USA
[2]Enthone, West Haven, CT, USA

A planar anode-supported intermediate temperature solid oxide fuel cell operating on syngas fuel at 750°C was analyzed in this study. The effects of varying syngas fuel inlet compositions on species and temperature distributions, water gas shift reaction rate, potential for carbon ... En savoir plus

A CFD Analysis of the Operating Conditions of a Multitube Pd Membrane for H2 Purification

B. Castro-Dominguez[1], R. Ma[1], A. G. Dixon[1], Y. H. Ma[1]
[1]Chemical Engineering Department, Worcester Polytechnic Institute, Worcester, MA, USA

The optimization of operating conditions in multitube membrane modules is highly complex. The multiple physics and irregular geometries involved create a challenge for predicting their behavior. This work analyzes the performance of H2 purification through a module containing seven ... En savoir plus

A Single Particle Thermal Model for Lithium Ion Batteries

R. Painter[1], S. Berryhill[1], L. Sharpe[2], S. K. Hargrove[2]
[1]Department of Civil Engineering, Tennessee State University, Nashville, TN, USA
[2]Department of Mechanical Engineering, Tennessee State University, Nashville, TN, USA

COMSOL® "Single Particle Model for Lithium-Ion Batteries” (Model ID: 14527) is generalized to include an energy balance. This is accomplished by approximating the solution phase polarization as a function of current and temperature. The theoretical approach for this work is similar to ... En savoir plus

Reliable Full-Wave EM Simulation of a Single-Layer SIW Interconnect with Transitions to Microstrip Lines

J. L. Chavez-Hurtado[1], J. E. Rayas-Sanchez[1], Z. Brito-Brito[1]
[1]ITESO - Universidad Jesuita de Guadalajara, Tlaquepaque, Jalisco, Mexico

We present a procedure to obtain reliable EM responses for a SIW interconnect with microstrip line transitions. The procedure focuses on two COMSOL® configuration settings: meshing size and simulation bounding box. Once both are properly configured, the implemented structure is tested by ... En savoir plus
