Breakthroughs in biomedicine and IT have provided a wealth (mountain) of data where the key post-genomic challenge is to transform this data into information that can be used to determine biomaterial function. Biomaterial functions arise from complex nonlinear interactions between biological processes occurring over multiple spatial and temporal scales Gaining an understanding of these ...

Flow separation is a common and interesting phenomenon in fluid mechanics with significant effects in practical applications. Thus, it has been the focus of intensive study for many years. The objective of this presentation is to investigate laminar separation flows over a backward-facing step and over a rectangular trench using COMSOL. --------------------------------- Carlo Gualtieri ...
From PDE Toolbox to COMSOL Multiphysics 3.2: Past, Present and Future of Teaching and Research in Thermo-fluids

This presentation deals with the investigation of new methods for the adsorption of carbon dioxide and water vapor from manned spacecraft atmospheres. The presentation touches not only the modeling of such methods, but also the important applications. Apart from modeling results on water adsorption and determination of heat transfer coefficients, an historical overview of spacecraft atmosphere ...

The thin shell of the LBT Adaptive Secondary Mirror has been manufactured, optically polished, and delivered. The operations and tests required before finally mounting it on the telescope have to be run very carefully, as they imply loads completely different from the ones of the adaptive operational modes - studied in the past with very encouraging results. Deformations and stresses that occur ...

To prepare for the installation of a combined audio-ANC-system for a very light jet (VLJ), a finite element model of the investigated cavity was developed.Both an eigenvalue analysis and a time harmonic analysis were performed. The latter was needed to determine the transfer functions between error sensors and actuators.The simulations were performed using COMSOL Multiphysics. The results of the ...

A parametric simulator for a dezincification process industrial device analysis has been developed. The device is built upon a COMSOL Multiphysics magneto-thermo-hydraulic coupled model in a cylindrical coordinate system.We study effects of electromagnetic forces on a cast iron load and consequently on Zn gas bubbles trajectories included in the metal.Trajectories are obtained according to mass ...

The research presented here shows a multiphysics model for a polymerelectrolyte transistor (PET) simulated in COMSOL Multiphysics.Dynamic transient response and current-voltage characteristics are determined from multiple simulations of an alkaline-acid-alkaline PET in a common collector configuration, showing transistor activity in the ionic currents of the device. This shows that increasing ...
Effects of Plasma Rotation and Magnetic Fields on Convection Flows in the Horizontal Burning High Intensity Discharge Lamps
OSRAM SYLVANIA, Beverly, MA, USA
In this presentation, the effect of a uniform applied magnetic field and a non-uniform field due to a line current (from the lead wire that powered the lamp) are studied and the magnetic fields required to center the arc plasmas are determined. The effects of plasma rotation induced by arc-tube rotation on plasma flows and temperatures are also studied. Critical slip velocities to change the flow ...
