Evaluating Clean Bench Designs Using CFD and Particle Tracing

A. Johnson [1] , M. Wright [1]
[1] Honeywell FM&T, Kansas City, MO, USA

At the Kansas City National Security Campus (KCNSC), simulation analysts are often called upon to evaluate designs and manufacturing processes performed in the plant. Precision mechanisms need to be assembled on clean benches that provide laminar airflow to prevent dust contamination. ... Mehr lesen

Computational Fluid Dynamics Modeling of the NASA Titan Wind Tunnel

[1] Space Science Institute, Boulder, CO, USA
[2] Department of Geology, University at Buffalo, Buffalo, NY, USA
[3] Department of Earth and Planetary Sciences, University of Tennessee - Knoxville, Knoxville, TN, USA

The equatorial region of Titan, the largest satellite of Saturn, has extensive expanses of aeolian dunes revealed in synthetic aperture radar (SAR) images and suggested to be composed of organics or organic-coated water ice. The dunes are among the youngest surface features and appear to ... Mehr lesen

Interaction of Microparticles in a Miniaturized Vacuum-Cleaner

[1] Vrije Universiteit Brussel, Department of Chemical Engineering, Brussels, Belgium
[2] Universiteit Twente, Mesoscale Chemical Systems MESA+, Enschede, The Netherlands

The ever-growing complexity of samples which need to be processed in e.g., environmental and biomedical/biochemical research, demand higher efficiencies of analytical techniques. Liquid chromatography (LC), mass spectrometry, among others, are analytical techniques that revolutionized ... Mehr lesen

Electron Trajectories in Scanning Field-Emission Microscopy

H. Cabrera [1],
[1] Swiss Federal Institute of Technology, Zurich, Switzerland

The Scanning Field Emission Microscopy (SFEM) is a novel technology similar to the better known Scanning Tunneling Microscopy (STM). In STM, electrons are exchanged between the outermost atom of a sharp tip and the outermost atom of a target over sub-nanometer distances by means of the ... Mehr lesen

Simulation of CMOS Compatible Sensor Structures for Dielectrophoretic Biomolecule Immobilization

H. Matbaechi Ettehad [1], S. Guha [1], C. Wenger [1],
[1] IHP, Frankfurt (Oder), Brandenburg, Germany

The aim of this paper is to optimize with COMSOL Multiphysics® simulation, the design geometry of a near field biosensor which could be used for dielectrophoretic (DEP) immobilization and simultaneous sensing of biomolecules of the order of nanometers to micrometers. COMSOL Multiphysics® ... Mehr lesen

Meshing Challenges in Simulating the Induced Currents in Vacuum Phototriode

S. Zahid [1], P. R. Hobson [1],
[1] Brunel University London, London, United Kingdom

Vacuum phototriodes (VPT) have been used as photodetectors for many years in particle physics experiments. For example, they were used in the OPAL experiment at LEP and are currently used in the endcap Electromagnetic Calorimeter of the CMS experiment, at CERN’s Large Hadron Collider. ... Mehr lesen

Innovation of Combustion Particle Control Technologies Assisted by Numerical Modeling

D. Rubinetti [1],
[1] Institute of Biomass and Resource Efficiency, University of Applied Sciences and Arts Northwestern Switzerland, Windisch, Switzerland

Worldwide efforts to promote the use of renewable energies include combustion-based technologies that produce substantial amounts of pollutants. In order to control the environmental impact a proper treatment of exhaust gases is required. This study describes the development of a ... Mehr lesen

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 ... Mehr lesen

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 ... Mehr lesen

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 ... Mehr lesen
