Design of Precision Magnetic Fields for Fundamental Neutron Symmetries new

M. Higginson-Rollins[1], C. Crawford[2]
[1]Department of Electrical & Computer Engineering, University of Kentucky, Lexington, KY, USA
[2]Department of Physics & Astronomy, University of Kentucky, Lexington, KY, USA

The traditionally magnetic design process involves guessing at a reasonable conductor geometry, using finite element analysis (FEA) software to calculate the resulting fields, and modifying the configuration iteratively to reach an acceptable solution. Taking the opposite approach, we ... Read More

Tuning Sensitivity to Ectopeptidase Rates in the Rat Hippocampus Using Numerical Simulations new

Y. Ou[1], S. Weber[1]
[1]University of Pittsburgh, Pittsburgh, PA, USA

We have created and optimized a multiphysics model in COMSOL Multiphysics® software that studies sensitivity to ectopeptidase rates in the rat hippocampus. Ectopeptidases are membrane-bound enzymes whose catalytic domains face the extracellular space (ECS) (Figure 1). They have ... Read More

Simulation of the Temperature Profile During Welding with COMSOL Multiphysics® Software Using Rosenthal's Approach new

A. Lecoanet[1], D. G. Ivey[1], H. Henein[1]
[1]Department of Chemical & Materials Engineering, University of Alberta, Edmonton, AB, Canada

A 3D finite element analysis is carried out, using COMSOL® software, to reproduce the thermal profile obtained with Rosenthal’s equation. The implemented heat transfer equation has been modified as a means to approximate Rosenthal’s solution. An analysis of the differences between the ... Read More

Modeling of Arc Welding Power Source new

E. S. Tschoepke[1], J. A. E. Mazzaferro[1], G. Paz[1]
[1]Universidade Federal do Rio Grande do Sul, Porto Alegre, RS, Brazil

Introduction: The main objective of the present work consists in modeling an arc welding heat source to allow predict peak temperature and cooling rate at specific points. The filler metal was deposited on a plate of 32mm thick with no chamfer, in bead on plate configuration, using five ... Read More

Analysis of 3-D Printed Structural Components for Cube Satellites new

C. Herzfeld[1]
[1]SPAWAR Systems Center (SSC) ATLANTIC, Charleston, SC, USA

Additive manufacturing uses 3D printing to build physical parts from CAD-based designs. The technology includes fused deposition modeling (FDM) and selective laser sintering (SLS) methods. 3-D printing is of particular interest for smaller, one-of-a-kind, customizable products. A cube ... Read More

Numerical Investigation of Micronozzle Performance for Various Nozzle Geometries new

P. A. Haris[1], T. Ramesh[1]
[1]National Institute of Technology Tiruchirappalli, Tiruchirappalli, Tamil Nadu, India

Design and manufacture of thrusters for producing very low thrust force in the range of milli or micro newtons using micronozzles has been actively developed in the last decade. The nature of propellant flow in such micronozzles differs from that of macro nozzles. In micronozzles, ... Read More

Using Computational Fluid-Dynamics (CFD) for the Evaluation of Tomato Puree Pasteurization: Effect of Orientation of Bottle new

A. R. Lespinard[1, 2], R. H. Mascheroni[1, 2]
[1]Centro de Investigación y Desarrollo en Criotecnología de Alimentos (CIDCA), La Plata, Buenos Aires, Argentina
[2]Universidad Nacional de La Plata (UNLP), La Plata, Buenos Aires, Argentina

Determination of the temperature in liquid foods may be derived by measurements or by modeling. However, the placement of thermocouple probes to record temperature in the container disturbs the flow patterns. For this purpose, Computational fluid-dynamics (CFD) offers a powerful tool for ...

Simulation of a Piezoelectric Loudspeaker for Hearing Aids and Experimental Validation new

G. C. Martins[1], P. R. Nunes[1], J. A. Cordioli[1]
[1]Federal University of Santa Catarina, Florianópolis, SC, Brazil

The use of piezoelectric materials in hearing aid loudspeakers, also called receivers, presents technical and economic advantages such as reducing the number of parts of the system and its manufacturing cost. However, the performance of such systems is still not competitive when compared ... Read More

An Approach to Modeling Vacuum Desorption new

C. F. Gomez[1], R. Schunk[1], R. F. Coker[1], J. Knox[1]
[1]NASA Marshall Space Flight Center, Huntsville, AL, USA

The objective of this simulation effort is to develop a mathematical model of vacuum desorption on a POC (Proof of Concept) canister loaded with Zeolite 13X/5A . This canister contains a pelletized adsorption bed which is used to adsorb H2O and CO2. Once this bed is fully saturated with ... Read More
