Heat Transfer and Phase Change

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 ... En savoir plus

[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. En savoir plus

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 ... En savoir plus

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

O. Capron[1], A. Samba[1], N. Omar[1], H. Gualous[2], P. Van den Bossche[1], J. Van Mierlo[1]
[1]MOBI - Mobility, Logistics and Automotive Technology Research Centre, VUB - Vrije Universiteit Brussel, Brussels, Belgium
[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 ... En savoir plus

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 ... En savoir plus

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, ... En savoir plus

Simulation and Experimental Validation of the Core Temperature Distribution of a Three-Phase Transformer

R. Barroso[1]
[1]Universidade Federal do Ceará, Fortaleza, Ceará, Brazil

This paper presents an application of COMSOL Multiphysics® software in the study of the temperature distribution of a 5kVA three-phase air-cooled transformer. A 3D, steady state model was utilized on the simulations. The interface with the surrounding air was modeled by Newton's Law of ... En savoir plus

R. Kreczkiuski[1], I. Neitzel[1]
[1]Faculdade de Telêmaco Borba - FATEB, Telêmaco Borba, Paraná, Brasil

No processo Kraft a madeira é reduzida a uma massa fibrosa. Neste processo são rompidas as ligações entre as estruturas da madeira separando as fibras. Esta operação, denominada de polpação, é realizada em um equipamento denominado de digestor. Este trabalho analisa o comportamento ... En savoir plus

Heat Transfer in Adsorption Heat Exchangers between Pellets and Fins

E. Laurenz[1], G. Füldner[1], L. Schnabel[1]
[1]Fraunhofer Institute for Solar Energy Systems (ISE), Freiburg, Germany

Adsorption heat exchangers (AdHXs) are important components in adsorption heat pumps and chillers, a primary energy efficient source of heating and cooling. Due to availability and established inexpensive manufacturing fin-and-tube type heat exchangers with beds of adsorption pellets in ... En savoir plus

Passive Indirect Evaporative Cooler

F. F. Dall'Agnol[1], A. Pavani[1]
[1]Center for Information Technology Renato Archer, Campinas, SP, Brazil

Evaporative coolers are viable alternative to air conditioners because of their low power consumption. However, in tropical humid environments the increased humidity that accompanies the cool air in the evaporative coolers causes an uncomfortable wet feeling, since it hinders the ... En savoir plus
