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 ...

Verification and Time Performance Analysis of COMSOL v3.5a for Solving the Electromagnetic Problem in a Superconductor Slab

Numerical analysis based on finite element method (FEM) represents a powerful approach to solve electromagnetic problems. For instance, FEM methods have been broadly used to calculate the critical state current distribution in high temperature superconductors of various geometries. In the near future, we intend to develop a tool in COMSOL v3.5a for the analysis of power applications, such as ...

Evaluation of CO2 Leakages From An Aquifer Storage

A. Thoraval[1], R. Farret[2], A. Cherkaoui[2], and P. Gombert[2]
[1]INERIS, Nancy, France
[2]INERIS, Verneuil, France

This paper presents preliminary estimations of CO2 overpressure into the reservoir and CO2 leakage through the caprock and the overburden. A simple, two-phase flow model in porous media based on Darcy’s law was used, in order to explore easily long time periods. The models produced by COMSOL Multiphysics allow sensitivity studies and preliminary evaluations of the relations between CO2 leakage ...

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 ...
