Simulated Annealing and Genetic Algorithm Optimization using COMSOL Multiphysics®: Applications to the Analysis of Ground Deformation in Active Volcanic Areas

A. Manconi[1], P. Tizzani[1][2], G. Zeni[1], S. Pepe[1], and G. Solaro[1][2]
[1]IREA, CNR, Napoli, Italy
[2]INGV, Osservatorio Vesuviano, Napoli, Italy

We combine the potentiality of COMSOL with Monte Carlo optimization procedures, referred to as Simulated Annealing and Genetic Algorithm, in order to analyze and interpret ground deformation measured in active volcanic areas. Through MATLAB® subroutines, we use FE (Finite Element) ... Read More

Hydrogen Vehicle Leak Modelling in Indoor Ventilated Environments

A. Hallgarth[1], A. Zayer[1], A. Gatward[2], and J. Davies[2]
[1]Hazard Research & Risk Consultants Ltd, Aberystwyth, Wales, United Kingdom

This paper presents and discusses HazRes’ research and results associated with the simulation and modelling of hydrogen release and dispersion events in indoor enclosed environments, using COMSOL Multiphysics. HazRes has developed a gas dispersion model in COMSOL, which takes into ... Read More

3D Modeling of Microwave Plasma Using Funer Model

O. Geoffroy[1] and H. Rouch[1]
[1]INOPRO, Villard de Lans, France

After previous microwave simulations done with very hard assumptions, we improve the model by using Funer model to improve prediction of plasma effects on the microwave coupling. Some parameters are still not well known and are used as adaptation parameters. An experience plan technique ... Read More

Long Term Performance Of Borehole Heat Exchanger Fields With Groundwater Movement

S. Lazzari, A. Priarone, and E. Zanchini
DIENCA, University of Bologna, Bologna, Italy

A numerical investigation of the long-term performance of double U-tube borehole heat exchanger (BHE) fields, in the case of non-negligible effects of groundwater movement, is performed by means of COMSOL Multiphysics. Two time periodic heat loads, with a period of one year, are studied: ... Read More

Absorbing Boundary Domain for CSEM 3D Modeling

J. Park[1], T.I. Bjørnarå[1], and B.A. Farrelly [2]
[1]Norwegian Geotechnical Institute(NGI), Oslo, Norway
[2]MultiField Geophysics AS, Norway

In the study, we present an efficient absorbing boundary domain technique whose main application is the 3D finite element (FE) modelling of the so-called controlled-source electromagnetic (CSEM) data, collected for the geophysical exploration. The developed technique is based on the ... Read More

Numerical Investigation of Mass Transfer with Two-Phase Slug Flow in a Capillary

W. Han, and B.H. Dennis
University of Texas, Arlington, TX, USA

The multiphase flow of two immiscible liquids in a microchannel was investigated numerically. A Y-shape micromixer was designed to produce a pattern of slugs from the flowing liquids. The mass transfer characteristics of this flow pattern are of primary interest in this study. A simple ... Read More

Strong Magnetic Field and Its Application

Y. Song
Huazhong University of Science and Technology, Wuhan, China

High magnetic field research has yielded fruitful results. Since 1913, associated with the magnetic field there are 19 Nobel Prizes, including a prize for medicine, five chemistry prizes, and 13 physics prizes. In recent years, the international community under the conditions of strong ... Read More

Numerical Analysis of the 3-omega-method

M. Feuchter, and M. Kamlah
Karlsruhe Institute of Technology (KIT)
Institute for Applied Materials
Karlsruhe, Germany

Determining the thermal conductivity of condensed matter attracted much attention in past years. While several techniques exist to measure the thermal conductivity of solids or thin films, the 3-omega-method is one of the most well-established due to its high accuracy. First, COMSOL ... Read More

Design and Analysis of Micro-tweezers with Alumina as Gripper Using COMSOL Multiphysics
