Use of COMSOL Multiphysics® for IAQ Monitoring in Cleanrooms

G. Petrone[1], C. Balocco[2]
[1]BE CAE & Test, Catania, Italy
[2]Department of Industrial Engineering, University of Firenze, Firenze, Italy

High levels of Indoor Air Quality (IAQ) in Operating Theatres (OT) is an important issue in order to contribute in prevention of Surgical Site Infections (SSI). Despite of specific plant layouts are applied for OT ventilation (e.g. unidirectional flow), the effective use conditions can ... Read More

Investigation of Mean-Flow Effects on Tubular Combustion Chamber Thermoacoustics Using a Burner Transfer Matrix Approach

A. Andreini[1], B. Facchini[1], A. Innocenti[1], D. Pampaloni[1]
[1]University of Florence, Florence, Italy

The paper presents a methodology to account for local mean-flow effects on thermo-acoustic instabilities to improve typical calculations performed under the zero-Mach number assumption. A 3D FEM model of a simplified combustor is solved with COMSOL Multiphysics® Pressure Acoustics ... Read More

Heat Transfer and Working Temperature Field of a Photovoltaic Panel under Realistic Environmental Conditions

E. Ruiz-Reina[1], M. Sidrach-de-Cardona[1], M. Piliougine[1]
[1]University of Málaga, Málaga, Spain

The aim of this work is the numerical study, by finite element analysis using COMSOL Multiphysics®, of the heat transfer and working temperature field of a photovoltaic panel under realistic wind and irradiation conditions. It is well-known that a great portion of the solar radiation ... Read More

Simulating Wear in Disc Brakes

N. H. Elabbasi[1], M. J. Hancock[1], S. B. Brown[1]
[1]Veryst Engineering, LLC., Needham, MA, USA

Wear is a complex phenomenon relevant to many problems involving frictional contact, such as mechanical brakes, seals, metal forming, and orthopedic implants. The rate of wear depends on the properties of the contacting materials and operating conditions. One widely used model of wear is ... Read More

[1]Technical School of Engineering, University of Valencia, Valencia, Spain
[2]Department of Applied Physics, Politechnical University of Valencia, Valencia, Spain

It has been demonstrated that is possible obtain the thermal parameters of geological layers of a BHE (Borehole Heat Exchanger) by fitting temperature evolution in an observer pipe inserted into borehole. Read More

Modelling of the Dynamical Fluorescent Micro-Thermal Imaging Experiment on the Heat Diffusion in the La5Ca9Cu24O41 Spin Ladder Compound

E. Khadikova[1], F. de Haan[1], P. H. M. van Loosdrecht[2]
[1]Zernike Institute for Advanced Materials, University of Groningen, Groningen, The Netherlands
[2]Department of Physics, University of Cologne, Köln, Germany

The dynamical fluorescent micro-thermal imaging (FMI) experiment has been used to investigate the phonon-magnon interaction in the 1D Heisenberg antiferromagnet La5Ca9Cu24O41. This material shows highly anisotropic heat conductivity due to the efficient magnetic heat transport along the ... Read More

Large and High Power Cylindrical Batteries - Analysis of the Battery Pack Temperature Distributions Using the COMSOL Multiphysics® and MATLAB® Simulation Softwares

[2]Laboratoire LUSAC, Université de Caen Basse Normandie, Cherbourg-Octeville, France

The temperature distributions inside two packs (in-line and staggered) made of large cylindrical lithium iron phosphate cells (of 18 Ah nominal capacity) are analysed in this paper during a 90 A constant discharge current. The analysis of the battery packs temperature distributions is ... Read More

Mathematical Model of Vacuum Foam Drying

M. Sramek[1], J. Weiss[2], R. Kohlus[1]
[1]Department of Food Processing Engineering, Institute of Food Science and Biotechnology, Hohenheim University, Stuttgart, Germany
[2]Department of Meat Science and Food Physics, Institute of Food Science and Biotechnology, Hohenheim University, Stuttgart, Germany

The mathematical model is closely related to the development of a novel drying method for high viscous and sticky materials. The foamed state facilitates diffusive moisture transport and therefore accelerating the drying process. Moreover the dried porous material can be easily converted ... Read More

Numerical Analysis of the Self-Heating Behaviour of Coal Dust Accumulations

D.Wu[1], E. Van den Bulck[1]
[1]Katholieke Universiteit Leuven, Department of Mechanical Engineering, KU Leuven, Belgium

Introduction Self-heating behaviour of dust accumulations is a multiphysics field coupled heat and mass transfer in the porous media. A typical experimental apparatus with a hot storage oven and mesh wire baskets has been taken as the study object. The influence of gas flow velocity, ... Read More
