An Examination of Wall Shear Stresses in Curved Arterial Vessels Using Bioresorbable Stents

D. W. Pepper [1], S. Pirbastami [1],
[1] University of Nevada - Las Vegas, Las Vegas, NV, USA

Bioresorbable stents are providing temporary mechanical support to keep a narrowed or blocked coronary artery open and restore the blood flow and will be gradually degraded and resorbed after the healing and remodeling of arterial wall. This new generation of stents has lower rates of ... Read More

Dynamic Simulation of a Polymer Molecule Using COMSOL Multiphysics®: DNA Separation in a Microchannel

J. Park [1], S. Monjezi [1], M. Palaniappan [1], J. D. Jones [1], B. Behdani [1],
[1] Missouri University of Science and Technology, Rolla, MO, USA

In this study, COMSOL Multiphysics was used to simulate DNA separation within a microchannel based on the entropic trapping mechanism. The entropic trapping mechanism involves DNA molecules passing through a series of obstacles in a microchannel and different lengths of DNA exhibiting ... Read More

A Phase Field Model for Lithium Ion Battery Particles

R. Painter [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

In this study, a three-dimensional (3-D) phase field model was developed to better understand the parameters impacting the LiFePO4 cathode material in lithium ion batteries. LiFePO4 has a strong tendency to separate into stable high Li+ concentration and low Li+ concentration phases, ... Read More

Modeling Internal Erosion Processes in Soil Pipes

J. L. Nieber [1], G. V. Wilson [2], G. A. Fox [3],
[1] University of Minnesota, St. Paul, MN, USA
[2] United States Department of Agriculture - Agricultural Research Service National Sedimentation Laboratory, Oxford, MS, USA
[3] North Carolina State University, Raleigh, NC, USA

The erosion of the interior of soil pipes is an important process in the fields of geomechanics and geomorphology. Soil pipes can form in water holding structures like dams and levees, and water flow through these structures becomes concentrated into the soil pipes as they evolve by the ... Read More

Numerical Modeling of High Aspect Ratio µPillars at Different Viscosities and Flow Rates

A. Mustafa [1], A. Erten [2], A. Eser [3], A. Cenk Aksu [3], A. Kiraz [1], M. Tanyeri [4], O. Yalcin [3]
[1] Department of Physics, Koç University, Istanbul, Turkey
[2] Department of Electrical Engineering, Osmaniye University, Osmaniye, Turkey
[3] Department of Bio Medical Engineering/School of Medicine, Koç University, Istanbul, Turkey
[4] Institute of Molecular Engineering, University of Chicago, Chicago, IL, USA

The advent of Micro/Nano fluidic technologies has enabled researchers from various fields to use these advancements for analysis and experiments. In this work we present such a device that can be used for analyzing coagulation of blood in a microchannel by measuring the displacement of ... Read More

Evaluation of the Induced Excitation of the Peripheral Vestibular System Using Micro Scale Inductors

S. Mukesh [1], P. Bhatti [1],
[1] School of Electrical and Computer Engineering, Georgia Institute of Technology, Atlanta, GA, USA

According to the National Health and Nutrition Examination Survey data, 35 % of US adults aged 40 years and older have evidence of balance dysfunction based on the modified Romberg test. In this vestibular dysfunction, patients are not able to see stabilized images on their retina during ... Read More

Increasing Dust Removal Efficiency of Electrodynamic Screens Using Frequency Optimization via COMSOL Multiphysics®

C. Morales [1], R. Eriksen [1], M. Horenstein [1], M. Mazumder [1],
[1] Boston University, Boston, MA, USA

Utility-scale photovoltaic (PV) and concentrated solar power (CSP) generation facilities are located in desert environments throughout the world to take advantage of the high availability of sunlight in these areas. Unfortunately, naturally occurring sandstorms in these deserts often ... Read More

Simulation of Acoustic Wave-Structure Interaction in a Quarter Wavelength Tube Energy Harvester

L. Melander [1], J. H. You [1],
[1] University of St. Thomas, St. Paul, MN, USA

An acoustic energy harvesting system at low frequency (~200 Hz) using lead zirconate titanate (PZT) piezoelectric cantilever plates placed inside of a quarter-wavelength straight-tube resonator has previously been studied using COMSOL and verified experimentally. When an incident ... Read More

Electrochemical Machining with Nonsymmetric Suction of Electrolyte Flow

M. Hashiguchi [1], D. Mi [1],
[1] Keisoku Engineering System Co. Ltd., Tokyo, Japan

In electrochemical machining process, it is very important to control electrolyte flow field to remove contamination such as slug, or gas to be generated by the machining process as well as heat control for electrolyte, machining tool and work piece. To reduce the overcut of workpiece, ... Read More

Towards Easily Tunable Mid-infrared Surface Plasmon Resonance With Gold Nano-crescent Structures

F. Liu [1],
[1] St. Mary's Ryken High School, Leonardtown, MD, USA
