[1]ATEKNEA Solutions Hungary, Budapest, Hungary
[2]ATEKNEA Solutions Catalonia, Barcelona, Spain

The application of pulsed electric fields (PEF) is well known in the food industry as an advanced technology for mass transfer improvement. A new potential adaptation area of PEF could be extracting a valuable antioxidant called polyphenol from wet olive pomace (WOP) which is a by ... 詳細を見る

MEMS Pirani Sensor for Pressure Measurements in the Fine- and High-Vacuum Range

M. Grau[1], F. Völklein[1], A. Meier[1], C. Kunz[1], P. Woias[2]
[1]RheinMain University of Applied Sciences, Institute for Microtechnologies, Rüsselsheim, Germany
[2]University of Freiburg, Department of Microsystems Engineering, Freiburg, Germany

A high performance MEMS Pirani sensor (VAC_03) was designed and optimized based on analytics. Due to the fact that this MEMS Pirani sensor is a 3D-Object, the calculation of the thermal radiation by analytics is limited. As the radiation behavior in the system is, beside the solid ... 詳細を見る

Elastoplastic Modeling and Experimental Verification of Solder-Substrate Interaction

C. Karl[1], C. Slater[1], M. Strangwood[1], K. Tank[2], S. O'Connor[2]
[1]University of Birmingham, Birmingham, UK
[2]Strip Tinning Ltd, Birmingham, UK

Solders are typically used to join similar or dissimilar metals, referred to as substrates. In some cases solders are also used to join completely different classes of materials. For example, a joint between copper busbar and silicon solar cell represents a set of dissimilar ... 詳細を見る

Thermal Field in a NMR Cryostat

A. D'Orazio[1], C. Agostini[1], S. Fiacco[1]
[1]Dipartimento di Ingegneria Astronautica, Elettrica ed Energetica - Sapienza University of Rome, Rome, Italy

Fundamental component of the NMR tomograph is the magnet. By using the property of superconductivity it is possible to achieve an induction field extremely homogeneous, stable and high. To maintain the material below the superconducting critical temperature (7.2K), the coils are immersed ... 詳細を見る

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 ... 詳細を見る

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 ... 詳細を見る

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 ... 詳細を見る

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 ... 詳細を見る
