[1]Department of Architecture, Middle East Technical University, Ankara, Turkey
[2]School of Architecture, Rensselaer Polytechnic Institute, Troy, NY, USA
[3]Department of Mechanical Engineering, Middle East Technical University, Ankara, Turkey

Sound energy distribution patterns within enclosed spaces are the basic concerns of architectural acoustics. Energy decays are analyzed for major acoustical parameter estimations, while spatial energy distribution and flow vectors are indicative in the analysis of sound energy ... Read More

Control of Real Distributed Parameter Systems Modeled by COMSOL Multiphysics® Software new

C. Belavý[1], G. Hulkó[1], S. Lipár[1], B. Barbolyas[1]
[1]Institute of Automation, Measurement and Applied Informatics, Faculty of Mechanical Engineering, Slovak University of Technology in Bratislava, Bratislava, Slovak Republic

In the paper, first a basic concept of the engineering approach for modeling and control of distributed parameter systems (DPS) based on interpretation of controlled systems as lumped input and distributed output systems (LDS) is introduced. Next, FEM modeling of temperature fields in ... Read More

Influence of a Refurbishing on an Old Residential Building’s Wall in Paris in Summer: Mass and Heat Transfer Approach new

K. Azos-Diaz[1], B. Tremeac[2], F. Simon[2], D. Corgier[2], C. Marvillet[1]
[1]Laboratoire de Chimie Moléculaire, Génie des Procédés Chimique et Energétique, Paris, France
[2]MANASLU Ing., Savoie Technolac, Le Bourget du Lac, France

The implementation of thermal insulation in old residential building walls could compromise the hygrothermal behavior of the construction, especially in summer time when it is placed inside. A bad installation of insulation could have consequences on the quality of indoor air conditions ... Read More

From Music to Non-Invasive Therapies via COMSOL Multiphysics® Models new

[1]Polytechnic University of Bucharest, Bucharest, Romania
[2]Student-Polytechnic University of Bucharest, Bucharest, Romania
[3]INFLPR -National Institute for Laser Plasma and Radiation Physics, Bucharest, Romania

Vibration and music therapies are non-invasive treatments having effective results although their basics are still disputed. By the application of COMSOL Multiphysics® software for modeling and analysis, some of the nonlinear physical phenomena laying on these applications may be ... Read More

Numerical Simulation of Evaporation Processes in Electron Beam Welding new

E. Salomatova[1], D. Trushnikov[1], V. Belenkiy[1], V. Tsaplin[1]
[1]Perm National Research Polytechnic University, Perm, Russia

In this paper describes an original method for indirect measurement of the vapor pressure and temperature in the keyhole in electron beam welding. This method is based on the determination of the concentration of chemical elements in the vapor above the welding zone. Taking into account ... Read More

Cloud Computations for Acoustics with Coupled Physics new

A. Daneryd[1], D. Ericsson[2]
[1]ABB Corporate Research, Västerås, Sweden
[2]COMSOL AB, Stockholm, Sweden

For certain classes of scientific and technical computations the cloud may offer easily accessible, scalable, and affordable gigantic computing power. A power that for these classes may lead to a step change in model and analysis complexity compared to what is feasible with dedicated ... Read More

Powder Densification Modeling of the Spark-Plasma-Sintering Process new

C. Maniere[1], C. Estournes[2], L. Durand[3], G. Chevallier[1], K. Afanga[1]
[1]Institute Carnot CIRIMAT, Toulouse, France
[2]University Paul-Sabatier, Toulouse, France
[3]CEMES, Toulouse, Toulouse, France

The Spark Plasma Sintering is a breakthrough way of elaboration of more or less complex shape materials from powder. This process allows the sintering of materials in few minutes compare to hours by conventional sintering. One of the main goals of the SPS modeling is to be able to ... Read More

Submarine Gas Hydrate Reservoir Simulations - A Gas/Liquid Fluid Flow Model for Gas Hydrate Containing Sediments new

S. Schlüter[1], T. Hennig[1], G. Janicki[1], G. Deerberg[1]
[1]Fraunhofer UMSICHT, Oberhausen, Germany

In the medium term, gas hydrate reservoirs in the subsea sediment are intended as deposits for carbon dioxide (CO2) from fossil fuel consumption. This idea is supported by the fact, that CO2 hydrates are more stable than methane hydrates at certain conditions. The potential of producing ... Read More

Optimization of the Slot Dimensions of a Large Air-gap Linear Synchronous Motor new

F. Giacometti[1], C. R. Lines[1], R. J. Cruise[1]
[1]Texchange Limited, London, UK

A COMSOL Multiphysics® model is used to optimise the slot geometry of a large air-gap linear synchronous motor. Fixed dimensions are used for the pole pitch, stator depth, stator width and air-gap, since the amount of available space is usually limited. A parametric sweep of the slot ... Read More
