Nonstandard High Voltage Electric Insulation Models

T. Christen[1]
[1]ABB, Corporate Research, Zürich, Switzerland

The design of modern electric insulation devices for medium and high voltage (HV) applications requires computational work that goes beyond solving just a Laplace equation for the electric potential, and limiting the electric field below critical values. Both field calculation and ... En savoir plus

Simulation of Differential Ion Mobility (DMS) Principle Coupled with Mass Spectrometry in Atmospheric Pressure

F. Sinatra[1], T. Wu[2], A. Avila[2], E. Nazarov[1], T. Evans-Nguyen[1], J. Wang[2]
[1]Draper Laboratory, Tampa, FL, USA
[2]University of South Florida, Tampa, FL, USA

Mass spectrometry is an analytical technique widely used in the scientific community to determine chemical composition of sample compounds. Typically, mass spectrometers perform their analysis under vacuum conditions, though atmospheric pressure mass spectrometers are becoming more ... En savoir plus

3D Simulation Of Fatty Acid Methyl Ester Production In A Packed Membrane Reactor

B. Sajjadi [1]
[1] University of Malaya, Malaysia

The current work is aimed to simulate the production of high quality fatty acid methyl ester (biodiesel) production from palm oil in a micro porous ceramic membrane reactor. The TiO2/Al2O3 ceramic membrane was used as the separator and catalytic bed. It was packed with potassium ... En savoir plus

Understanding the Transition Flow Region through Modeling in COMSOL Multiphysics® Software

J. Sturnfield [1],
[1] Dow Chemical, Freeport, TX, USA

The pore sizes of many membranes being studied for separating the components in gas mixtures are on the scale of nanometers. Depending on the specific gases and pressures being used, this scale will put the flows in the Transition between Slip Flow and Knudsen regime. The differential ... En savoir plus

Coupled Heat, Moisture and CFD Modeling in the Built Environment

K. Kompatscher [1], S. Kochen [1], A. M. W. van Schijndel [1], H. L. Schellen [1]
[1] Department of the Built Environment, Eindhoven University of Technology, Eindhoven, The Netherlands

Museum buildings strive for a stable indoor climate to reduce the risk of cultural object degradation. An incorrect temperature or relative humidity can induce or accelerate deterioration processes such as biological, chemical or mechanical degradation. In order to reduce these risks, ...

Simplified Numerical Model of an Axial Impeller

A.-M. Georgescu[1], S.-C. Georgescu[2]
[1]Hydraulics and Environmental Protection Department, Technical University of Civil Engineering, Bucharest, Romania
[2]Hydraulics Department, University “Politehnica”, Bucharest, Romania

We propose a simplified numerical method to model the flow field downstream of an axial impeller. The method can be used for any axial hydraulic machinery for which, one is less interested by the flow between the blades, than by the flow field downstream of the machinery. The method is ...

CFD Modeling for the Ventilation System of a Hospital Room

A. Kermani [1],
[1] Veryst Engineering LLC, Needham, MA, USA

Indoor ventilation with good air quality control prevents infection with minimizing the spread of airborne respiratory and other infections in hospitals. CFD can be utilized to optimize flow pattern in clean rooms especially hospital clean rooms. More than two million people in Europe ... En savoir plus

Orientation of Piezoelectric Crystals and Acoustic Wave Propagation

G. Zhang[1]
[1]Clemson University, Clemson, SC, USA

Surface acoustic wave (SAW) devices are commonly used as wireless filters, resonators, and sensors. The confinement of acoustic energy near the surface of a piezoelectric substrate in a SAW sensor makes it highly sensitive for discerning surface perturbation. As sensors, SAW devices have ...

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 ... En savoir plus

Multiphysics Process Simulation of Static Magnetic Fields in High Power Laser Beam Welding of Aluminum

M. Bachmann[1], V. Avilov[1], A. Gumenyuk[1], M. Rethmeier[1]
[1]BAM Federal Institute for Materials Research and Testing, Berlin, Germany

The article deals with the application of the Hartmann effect in high power laser beam welding of aluminum. The movement of liquid metal in a magnetic field causes electric currents which build a Lorentz force that decelerates the original flow. The numerical model calculates the ... En savoir plus
