Particle Tracing: Analysis of Airborne Infection Risks in Operating Theatres

P. Apell[1], S. Hjalmarsson[1], T. Lindberg[1], I. Wernström[1], Y. Tarakonov[1], A. Erichsen Andersson[2], M. Karlsteen[1]
[1]Department of Applied Physics, Chalmers University of Technology, Göteborg, Sweden
[2]Sahlgrenska University Hospital, Department of Anesthesia, Surgery and Intensive Care, Göteborg, Sweden

Patients undergoing surgery are sensitive to infections. The operation staff may spread 10^4 particles per person per minute, of which ten percent are presumed bacteria-carrying. We visualize the influence of the personnel on the air and particle flows for the two most common ventilation ... Mehr lesen

Numerical Study and Simulation in COMSOL Multiphysics of the Dilution Process during Dust Sampling in Dry Machining

B. Wenga-Ntcheping[1], A. Djebara[1], R. Kamguem[1], J. Kouam[1], V. Songmene[1]
[1]University of Quebec-École de Technologie Supérieure, Montreal, Canada

Dilution’s issue during dry machining have raised the interest’s environmental researchers and engineers. In fact, the sampling of dust emitted during dry machining was a serious problem for air quality evaluation at the workplace. Furthermore, the best sampling of fine and ultrafine ... Mehr lesen

Progress in Numerical Simulation of HIIPER Space Propulsion Device

P. Keutelian[1], A. Krishnamurthy[1], G. Chen[1], B. Ulmen[1], G.H. Miley[1]
[1]University of Illinois at Urbana-Champaign, Champaign, IL, USA

HIIPER is an experimental space propulsion device using a helicon and an IEC as a plasma generation and acceleration stage, respectively. There is an experiment in progress, but for true rapid iteration and to model the performance of the engine, COMSOL is a strong candidate for ... Mehr lesen

SWRO (Desalination) Biofilm Remediation Technology Utilizing Centrifugal Micro-Fluids

E.M. Glenn[1]
[1]University of California, Irvine, CA, USA

Water-and-energy supply is a global issue of paramount importance. The demand for safe potable water is quickly exceeding the limits of natural regional water resources. Like oil, water is a finite resource; unlike oil, however, water has no alternatives. Water, energy and their ... Mehr lesen

Modeling of Laminar Flow Static Mixers

[1]Veryst Engineering LLC, Needham, MA, USA
[2]Nordson EFD, East Providence, RI, USA

Laminar flow static mixers are accurate, inexpensive fluid mixing devices that can handle a wide range of fluids and mixing proportions. They have a wide range of industrial applications, especially in the consumer product, pharmaceutical, biomedical, and petrochemical industries. A good ... Mehr lesen

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 ... Mehr lesen

Steps for the Optimization of Pipe and Tubing Extrusion Dies

J.R. Puentes[1], T.A. Osswald[1], S. Schick[2], J. Berg[2]
[1]Polymer Engineering Center, University of Wisconsin, Madison, WI, USA
[2]TEEL Plastics, Baraboo, WI, USA

The extrusion of polyolefin pipes suffers degradation due to mechanical design problems of the extrusion die that is commonly used. This study uses numerical and computational approaches to detect problematic areas in the die geometry. Simulations show that in the conventional die there ... Mehr lesen

Modeling the ELENA Electron Cooler with COMSOL Multiphysics® Software

G. Tranquille[1]
[1]CERN, Geneva, Switzerland

ELENA is a small cooler decelerator ring at CERN which will be built to increase substantially the number of usable antiprotons delivered to experiments for studies with antihydrogen and antiprotonic nuclei. COMSOL Multiphysics® software has been used to completely model the ELENA ... Mehr lesen
