Model of a Heavy Metal Adsorption System using the S-Layer of Bacillus Sphaericus

J. Orjuela, and A. González
Dept. de Ingeniería Química Facultad de Ingeniería
Universidad de los Andes
Bogotá
Colombia

A bidimensional and pseudo homogenous model was proposed for the study of mass transfer in the bioadsorption process of chromium VI in the S-layer of immobilized Bacillus sphaericus in a packed column. The implementation of such a model in COMSOL Multiphysics will be explained in ... Read More

Boundary Element Technique in Petroleum Reservoir Simulation

M. Liu, and G. Zhao
University of Regina
Regina, SK
Canada

Petroleum reservoir simulation is a process of modeling the complex physical phenomena inside a reservoir. This study presents an application of an analytical based numerical scheme so called the Boundary Element Method (DRBEM). It is proven to be able to provide a computationally ... Read More

Study of Hard-and Soft- Magnetorheological Elastomers (MRE’s) Actuation Capabilities

J. Roche[1], P. Von Lockette[1], and S. Lofland[2]
[1]Mechanical Engineering Dept., Rowan University, Glassboro, NJ
[2]Physics and Astronomy Dept., Rowan University, Glassboro, NJ

In this study, magneto-rheological elastomer (MRE) composite beams made of Barium hexaferrite (BaM) and Iron (Fe) powders combined with a highly-compliant matrix material were simulated using COMSOL\'s Solid Mechanics and AC/DC modules. The goal of the work was to develop models capable ... Read More

Coupled Electromagnetic - Dynamic FEM Simulation of A High Frequency MEMS Energy Harvester

E. Topal
Middle East Technical University
Ankara
Turkey

In this study, a detailed finite element model coupling the motion dynamics and electromagnetics of a diaphragm based MEMS vibration energy harvester is presented. The energy harvester converts low frequency vibrations to high frequency response by magnetic actuation of a diaphragm ... Read More

Computational Acoustic Attenuation Performance of Helicoidal Resonators

W. Lapka
Poznan University of Technology
Poznan, Poland

This paper concerns the problem of obtaining proper acoustic attenuation performance through computations. COMSOL was used to solve acoustics systems with helicoidal resonators in the frequency domain. Based on the studies of insertion and transmission loss of helicoidal resonators, a ... Read More

Numerical Study of the Effect of Fins on the Natural Convection Driven Melting of Phase Change Material

C. Liu, and D. Groulx
Mechanical Engineering
Dalhousie University
Halifax, NS
Canada

Natural convection has to be accounted and simulated for in order to properly describe the physics encounter in the phase change process. A simplified two-dimensional model was created in COMSOL 4.1. Natural convection was accounted for by adding a volume force and using the ... Read More

Poromechanics Investigation at Pore-scale Using Digital Rock Physics Laboratory

S. Zhang[1],
N. Saxena[2],
P. Barthelemy[1], and
M. Marsh[1]
[1]Visualization Sciences Group, Burlington, MA, USA
[2]Stanford University, Palo Alto, CA, USA

Understanding the rock structure at nano to micro scale is of growing importance in geology, oil and gas, and hydrology. New approaches that relies on a variety of high resolution 3D imaging techniques offered tremendous potential. These new approaches, in the meanwhile, introduce ... Read More

A Coupled Analysis of Heat and Moisture Transfer in Soils

E. Evgin, J. Infante Sedano, and Z. Fu
University of Ottawa
Ottawa, ON
Canada

This paper is a part of a study on energy piles for heating and cooling of buildings. Energy piles are used for two reasons: (1) to transfer structural loads to foundation soils, and (2) to transfer heat from foundation soils to the building for space heating in winter time and for ... Read More

Calculating and Observing Opto-Mechanically Induced Surface Acoustic Waves in a Silica Whispering Gallery Microresonator

J. Zehnpfennig
Photonics Research Center
United States Military Academy
West Point, NY

Here we calculate opto-mechanically induced Surface Acoustic Waves upon a silica microresonator using COMSOL. Using conservation of momentum, we show both analytically and numerically that the photonphonon interaction within the resonator cavity causes a moving train of electrodes - a ... Read More

Wall Effect on A Spherical Particle Settling along The Axis of Cylindrical Tubes Filled with Carreau Model Fluids

D. Song[1], R. Gupta[1], and R. Chhabra[2]
[1]Dept. of Chemical Engineering, West Virginia University, Morgantown, WV
[2]Indian Institute of Technology, Kanpur, India

The effect of finite boundaries on the drag experienced by a rigid sphere settling along the axis of cylindrical tubes filled with Carreau model fluids has been examined systematically over a wide range of condition. As expected, the presence of finite boundaries leads to an increase ... Read More
