Thermal and Laminar-Fluidic Workbench for a metric Portion of a Gun

M. Brun
Nexter Systems, Versailles, France

Part of a 120mm gun has been represented as a perforated conic iron solid, surrounded by an annular screen. Inside the gun are limit conditions of isolation or thermal flux. The screen is described as a shell, receiving solar heat and exchanging with the outside atmosphere. It bears a defined number of holes on its top and bottom lines, maintaining semi-captive air between itself and the gun. ...

The Effect of Cartilaginous Rings on Deposition by Convection, Brownian Diffusion and Electrostatics

H. Akerstedt
Luleå University of Technology, Luleå, Sweden

This paper presents a numerical study of the deposition of spherical charged nanoparticles caused by convection and Brownian diffusion in a pipe with a cartilaginous ring structure. The model is supposed to describe deposition of charged particles in the upper generations of the tracheobronchial tree of the human lung. The upper airways are characterized by a certain wall structure called ...

Surface coating can fullfil their function satisfactorily over an extended period of time only if there is a good bond between the concrete substrate and the coating. The most numerous cases of blistering affect the airtight covers of the concrete subjected to negative pressures of humidity from the support. The general objective of this study is the understanding of the blistering phenomenon. ...

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 ...
