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

Using High Pressure Chemical Vapor Deposition to Make Multimaterial Optical Fibers

S. Chaudhuri [1], J. V. Badding [1],
[1] Pennsylvania State University, University Park, PA, USA

Ever since its advent optical fibers have revolutionized the communication technology but apart from communication they are being used in a variety of other areas such as medical technology, sensing, laser sources in the form of fiber lasers, amplifiers, cutting and drilling, defense ... Read More

Application of COMSOL Multiphysics® Software to Model Temperature Changes in Buildings with PCM Incorporated in Their Elements

N. P. Sharifi [1], A. A. N. Shaikh [1], A. R. Sakulich [1],
[1]Department of Civil and Environmental Engineering, Worcester Polytechnic Institute, Worcester, MA, USA

Reducing HVAC energy consumption in buildings has provoked a lot of thought and has, subsequently, drawn a lot of attention. Out of the several methods that have been introduced to achieve this goal, the usage of Phase Change Materials (PCMs) in the structural components is one of the ... Read More

3D Simulation of Laser Interstitial Thermal Therapy in the Treatment of Brain Tumors

M. Nour [1], A. Lakhssassi [1], E. Kengne [1], M. Bougataya [1],
[1] Université du Québec en Outaouais, Gatineau, QC, Canada

Abstract: Due to the restriction of the number of probes that a patient can tolerate, and the inaccurate information provided by the invasive temperature measurements, which provide information only at discrete points, a mathematical model simulation is more effective to help doctors in ...

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 ... Read More

Parameter Estimation in a Single Particle Model Using COMSOL Multiphysics® Software and MATLAB® Optimization

B. Rajabloo [1], M. Désilets [1], Y. Choquette [2],
[1] Département de Génie Chimique et de Génie Biotechnologique, Université de Sherbrooke, QC, Canada
[2] Institut de recherche d’Hydro-Québec, Varennes, QC, Canada

When it comes to study the behavior of the secondary batteries, physics-based models are more representative of the real behaviour than equivalent circuit models, especially for the estimation of the life and capacity fading. On the other hand, the complexity and computational cost of ... 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

A Computational Acoustic Interrogation of Damage to Wind Turbine Blades

R. Canturk [1], M. Inalpolat [1],
[1] University of Massachusetts - Lowell, Lowell, MA, USA

Modern wind turbine blades consist of composite airfoil shaped structures that form a hollow acoustic cavity. Because of continually varying aerodynamic forces, gravitational loads, lightning strikes, and weather conditions, all blades will experience leading and trailing edge splits, ... Read More

[1] University of Tennessee, Knoxville, TN, USA
[2] Oak Ridge National Laboratory, Oak Ridge, TN, USA

Introduction: The numerical solution to the neutron transport equation is employed to study a variety of problems in nuclear engineering applications, including for both eigenvalue and fixed source studies. Historically, multiphysics analysis at the HFIR has utilized these solutions to ... Read More

Computational Design and Optimization of Bone Tissue Engineering Scaffold Topology

N. P. Uth [1], J. Mueller [2], B. Smucker [3], A. Yousefi [1],
[1] Department of Chemical, Paper, and Biomedical Engineering, Miami University, Oxford, OH, USA
[2] Research Computing Support, Miami University, Oxford, OH, USA
[3] Department of Statistics, Miami University, Oxford, OH, USA

Introduction: Bone tissue has a limited ability for regeneration; critically sized defects cannot self-heal and require medical intervention. Bone tissue engineering (TE) circumvents this issue by growing replacement bone tissue from the patient’s own cells inside scaffolds. TE scaffolds ... Read More
