Modeling and Analysis of Aberrations in Electron Beam Melting (EBM) Systems

D. Svensson [1], A. Azhirnian [2],
[1] Arcam AB, Mölndal, Sweden
[2] Chalmers University of Technology, Gothenburg, Sweden

Arcam AB has pioneered additive manufacturing using the electron beam melting (EBM) technology which provides a cost efficient and novel way of producing titanium components for the orthopedic and aerospace industries. In the heart of the EBM technology is the electron beam – whose ... Per saperne di più

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 ... Per saperne di più

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 ... Per saperne di più

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 ... Per saperne di più

Microfluidic Simulation of a Separation System of T.cruzi from Blood Samples

[1] Department of Biomedical Engineering, University of Los Andes, Bogotá, Colombia
[2] Department of Electrical and Electronics Engineering, Microelectronics Center, University of Los Andes, Bogotá, Colombia

In 2014, it was estimated that there are between 6 to 7 million people worldwide infected by Chagas disease and approximately 25 million people are currently at risk. The parasite Trypanosoma cruzi (T. cruzi) causes this disease and according to the World Health Organization (WHO) it can ... Per saperne di più

HIIPER Space Propulsion Simulation Using AC/DC Module

Z. Chen [1], D. Ahern [1], G. Miley [1],
[1] University of Illinois at Urbana-Champaign, Urbana, IL, USA

The Helicon Injected Inertial Plasma Electrostatic Rocket (HIIPER) is an electric space propulsion concept being studied that utilizes a helicon source to generate a plasma and metal grids from inertial electrostatic confinement (IEC) fusion experiments to accelerate ions, generating a ...

Electromagnetic Modeling of Field Emitter Cathodes Inside an L-Band RF Gun at Fermilab Using COMSOL®

H. Panuganti [1,2,3], P. Piot [1,3],
[1] Northern Illinois Center for Accelerator and Detector Development (NICADD), Northern Illinois University, DeKalb, IL USA
[2] Department of Mechanical Engineering, Northern Illinois University, DeKalb, IL, USA
[3] Fermi National Accelerator Laboratory (FNAL), Batavia, IL, USA

Field-emitter (FE) electron sources offer significant advantages over photocathode and thermionic sources due to their ability to be operated without the need for an auxiliary laser system or a heating source. While FE cathodes have been traditionally used in DC environments, we explore ... Per saperne di più

Quantitative Assessment of Secondary Flows of Single-phase Fluid through Pipe Bends

Z. Kaldy [1], O. Ayala [1],
[1] Department of Engineering Technology, Old Dominion University, Norfolk, VA, USA

Single-phase fluid flow was simulated passing through various three dimensional pipe elbows. The simulations varied by Reynolds number, curvature ratios, and sweep angles and were all conducted using the k-ε model available in COMSOL Multiphysics® software. The intent of this research ...
