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

Modeling Partially Absorbing Biosensors

D. Kappe[1], A. Hütten[1]
[1]Bielefeld University, Bielefeld, Germany

Designing and constructing a lab-on-a-chip device poses a variety of questions. Transport of all required substances, detection of the analyte and its deposition on a sensor have to be incorporated. Different strategies have been developed to achieve good coverages of the sensor, like ... En savoir plus

Modeling Low Frequency Axial Fluid Acoustic Modes in Continuous Loop Piping Systems

E. Gutierrez-Miravete[1], E.R. Marderness[2]
[1]Rensselaer Polytechnic Institute, Hartford, CT, USA
[2]General Dynamics-Electric Boat, Groton, CT, USA

Industrial fluid systems often involve continuous piping loops. These systems consist of varying lengths of pipes and hoses connecting multiple components together. Fluid resonances can detrimentally affect the operation of fluid systems and components. This work used COMSOL to ... En savoir plus

Optimization of the Supersonic Gas Jets' Parameters for In-Gas-Jet Nuclear Spectroscopy Studies

A. Zadvornaya [1], Y. Kudryavtsev [1],
[1] KU Leuven, Leuven, Belgium

The in-gas-jet laser ionization and spectroscopy method (Figure 1) that has been developed at KU Leuven allows to produce and to perform laser spectroscopy of short-lived radioactive isotopes created in different types of nuclear reactions [1,2]. To realize the advantages of in-gas-jet ... En savoir plus

Modeling and Simulation of the Consolidation Behaviour of Cemented Paste Backfill

L. Cui [1], M. Fall [1],
[1] University of Ottawa, Ottawa, ON, Canada

In underground mining operations, the mined-out spaces (called stopes) need to be backfilled to maintain the stability of surrounding rock mass and increase the ore recovery. Cemented paste backfill (CPB), a mixture of water, binder, and tailings, has been intensively utilized in ... En savoir plus

Thermal Modeling of a Honeycomb Reformer Including Radiative Heat Transfer

J. Schöne[1], A. Körnig[1], W. Beckert[1]
[1]Fraunhofer IKTS, Dresden, Germany

Reformer and catalytic burners are common components in fuel cell systems, crucial for efficient preparation of fuel and exhaust gases of the fuel cell stack. We intend to show the influence of radiation to the temperature distribution inside of a reformer unit. The model consists of an ... En savoir plus

Single-Phase Modeling in Microchannel with Piranha Pin Fin

X. Yu [1], C. Woodcock [1], Y. Peles [2], J. Plawsky [1],
[1] Rensselaer Polytechnic Institute, Troy, NY, USA
[2] University of Central Florida, Orlando, FL, USA

Microchannel has shown potential to dissipate high heat flux in past years [1][2]. At the same time, liquid cooling attracts more and more attention from researchers for its favorable thermal properties and ability to cool down hot and keep acceptable system temperature [3][4][5]. This ... En savoir plus

Numerical Modeling and Performance Optimization Study of a Diaphragm Pump for Medical Application

I. Lupelli[1], P. Gaudio[1], A. Malizia[1], R. Quaranta[1]
[1]Department of Industrial Engineering, University of Rome “Tor Vergata”, Roma, Italy

In this contribution we present the results of the numerical modeling and performance optimization study of a diaphragm pump for drug infusion. The main objective is to develop a numerical model that replicates the pumping cycle (400ms) and also provides indications about the variation ... En savoir plus

Design and Simulation of a Microscale Magnetophoretic Device for the Separation of Nucleated Fetal Red Blood Cells from Maternal Blood

G. Schiavone[1], D.M. Kavanagh[2], and M.P.Y Desmulliez[2]

[1]Politecnico di Torino, Torino, Italy
[2]MIcroSystems Engineering Centre, School of Engineering & Physical Sciences, Heriot-Watt University, Edinburgh, Scotland, United Kingdom

Intense research has been carried out into methods that aim at harvesting fetal cells from maternal blood as substitutes to amniocentesis and chorionic villus sampling. This work focuses on the separation of fetal nucleated red blood cells from the maternal circulation based on their ... En savoir plus

Assessment of Anterior Spinal Artery Blood Flow following Spinal Cord Injury

M. Alshareef[1], A. Alshareef[2], V. Krishna[3], M. Kindy[3], T. Shazly[4]
[1]College of Medicine, Medical University of South Carolina, Charleston, SC, USA
[2]Department of Biomedical Engineering, Duke University, Durham, NC, USA
[3]Department of Neurosurgery, Medical University of South Carolina, Charleston, SC, USA
[4]Department of Mechanical Engineering, University of South Carolina, Columbia, SC, USA

The incidence of spinal cord injury (SCI) in the US is approximately 12,000 individuals annually, due to various forms of trauma and disease. Diminished flow over a prolonged period of time can cause permanent spinal damage. We constructed a 3D finite element model of the spinal cord to ... En savoir plus
