Porous membranes with pore sizes in the micrometer scale are required in many micro systems dedicated to biological and chemical applications. If their thickness is in the same dimension like the pore diameter they are called microsieves. On the one hand, a thin membrane guarantees a small flow resistance but on the other hand the mechanical strength is reduced. We developed a process which ...

TAP (Temporary Analysis of Products) reactors are powerful instruments to study the kinetics of catalytic reactions. Their basic principle, exposition of evacuated solids of interest to narrow pulses containing very small amounts of gases, and measuring the concentrations of outgoing molecules permits to study practical catalysts under the conditions approaching those of molecular beam ...

Microsoft Technical Computing

Modelling of Selected Electromechanical Phenomena in the DC Machine

M. Antczak, P. Idziak, and W. Lyskawiski
Poznań University of Technology, Poland

The paper presents the results of the experiment consisting in determination of the influence of the magnetic field on deformations of the stator and the rotor of the DC motor. The numerical model of the motor for the frameless DC machine of the G series has been elaborated. Real material properties and the phenomenon of the magnetic circuit saturation have been taken into consideration. The ...

Analysis Of The Design Criteria For Ancient Greek And Roman Catapults

K.M. Paasch
Center for Product Development, Mads Clausen Institute, South Danish University, Denmark

This paper will give a short overview of use of COMSOL Multiphysics for analyzing ancient Greek and Roman catapults with the main focus on the energy storing torsion springs. Catapults have been known and used in the Greek and Roman world from around 399 BC and a fully standardized design for powerful torsion catapults emerged around 270 BC, based on one basic factor, the diameter of the torsion ...
