Finite Element Method Plasma Simulation of Nitrogen Contaminated Ceramic Metal Halide Lamps

P. Juhász[1], S. Beleznai[1], I. Maros[1]
[1]Budapest University of Technology and Economics, Budapest, Hungary

The ceramic metal halide lamps belong to the most efficient high intensity light sources of these days. Presently it is the nitrogen contamination that causes the most significant problems during ignition. If this material gets into the lamp's interior in high concentrations, it will ...

Modeling Transient Adsorption/Desorption Behavior in a Gas Phase Photocatalytic Fiber Reactor

S. Denys [1], J. Van Walsem [1],
[1] Sustainable Energy, Air & Water Technology, Department of Bioscience Engineering, University of Antwerp, Belgium

Integration or retrofitting of photocatalytic air purifying units into HVAC (Heating, Ventilation and Air Conditioning) equipment is an interesting approach for abating indoor air pollution and removal of volatile organic compounds. An attractive possibility is the use of glass fiber ... En savoir plus

Modeling of Transport Phenomena in Metal Foaming

B. Chinè[1], M. Monno[2]
[1]Laboratorio MUSP Piacenza, Italy; ITCR, Esc. Ciencia e Ing. Materiales, Cartago, Costa Rica
[2]Laboratorio MUSP, Piacenza, Italy; Politecnico di Milano, Dip. Meccanica, Milano, Italy

Metal foams are interesting materials with many potential applications in engineering. Foamed metals or alloys include gas voids in the material structure with the real possibility to modify ad hoc their physical properties. Following our previous efforts aimed to simulate and study the ... En savoir plus

Modeling of Expanding Metal Foams

B. Chinè[1,2], M. Monno[3]
[1]Laboratorio MUSP, Macchine Utensili e Sistemi di Produzione, Piacenza, Italy
[2]School of Materials Science and Engineering, Costa Rica Institute of Technology, Cartago, Costa Rica
[3]Politecnico di Milano, Dipartimento di Meccanica, Milano, Italy

Metal foams are interesting materials with many potential applications. They are characterized by a cellular structure represented by a metal or metal alloy and gas voids inside (Fig.1). A common metallic cellular material is aluminum foam which can be produced metallurgically by heating ... En savoir plus

Design and Simulation of Valveless Piezoelectric Micropump

L. Nayana[1], P. Manohar[1], S. Babu[1]
[1]Department of Electrical Engineering, Visvesvaraya Technological University, Bangalore, Karnataka, India

In this paper some discrete parts of a valveless piezoelectric micropump for drug delivery system is designed and simulated. The core components of the micropump are actuator unit that converts the reciprocating movement of a diaphragm actuated by a piezoelectric actuator into a pumping ... En savoir plus

Prediction of Transformer Load Noise

M. Kavasoglu[1], R. Haettel[1], and C.H. Ploetner[2]
[1]ABB Corporate Research, Västerås, Sweden
[2]ABB Transformers, Varennes, Canada

Transformers, as any other industrial products, have to comply with various requirements on noise levels. Three main sources of noise can be identified in transformers: no-load noise or core noise generated by magnetostriction in the core steel laminations, load noise produced by ... En savoir plus

Comsol’s New Thermoviscous Interface and Computationally Efficient Alternative Formulations for FEM

W. R. Kampinga[1], and Y. H. Wijnant[2]
[1]Reden, Hengelo, Netherlands
[2]University of Twente, Enschede, Netherlands

Three efficient alternatives to the model in COMSOL’s thermoacoustics interface are presented. The higher efficiency of these models are explained from theory and are demonstrated by means of two examples. En savoir plus

Using a Level-Set Model to Estimate Dwell Time in a Vacuum Dewatering Process for Paper

K. Rezk[1]
[1]Department of Energy, Environmental and Building Technology, Karlstad University, Kronoparken, Sweden

Water removal during paper manufacturing is an intensive energy process. The dewatering process generally consists of four stages in which the first three stages, water is removed mechanically through vacuum pulses and pressing.The fourth stage involve thermal drying. The vacuum ... En savoir plus
