Loudspeaker Simulations in a Car Cabin

F. Malbos [1], M. Bogdanski [2], M. Strauss [2]
[1] Harman France, Paris, France
[2] Harman Becker Automotive Systems, Straubing, Germany

The goal of this study is to improve the audio simulation accuracy for automotive applications. COMSOL® Acoustics Module and LiveLink™ for MATLAB® were used to simulate the sound pressure generated by a loudspeaker in a car cabin. A comparison between simulated and measured sound ... Read More

Parametric Investigation of the Common Geometry Shapes for Added Mass Calculation

J. H. Lee [1], A. Koushesh [1],
[1] American University of Sharjah, United Arab Emirates

This work is aimed to demonstrate how variation of geometries' parameters would affect the fluid loading effect in water using COMSOL Multiphysics and compared with analytical data. When a structure is placed in water, the interaction between the water and the structure plays an ... Read More

Multiphysics Design of a Klystron Buncher

A. Leggieri [1], D. Passi [1], F. Di Paolo [1], G. Saggio [1]
[1] University of Rome, Rome, Italy

The Multiphysics design of a 130 GHz klystron Buncher cavity is described in this paper. In this high frequency range, dimensions are critical and expose the device to multiple physics effects, due to the power dissipations, affecting the electromagnetic performances. The proposed device ... Read More

Using Multiphysics for Detecting Atmospheric Ice Through MuVi Graphene - Atmospheric Icing Sensor

U. N. Mughal [1],
[1] Narvik University College, Norway

This paper is a preliminary design study to develop a hybrid atmospheric icing sensor which have an adequate potential to detect an icing event, icing type and icing rate together with icing load. The physics to detect icing event and icing type have been numerically understood using ... Read More

Coupled Heat and Mass Transfer Model to Simulate Hygrothermal Behavior of Bio-Based Materials

M. Asli [1], F. Brachelet [1], A. Chauchois [1], E. Antczak [1]
[1] Université d'Artois, Béthune, France

This poster presents a numerical modeling approach for hygrothermal behavior of bio-based materials. The mathematical model describes the heat and moisture transfer through a wall of bio-based materials. The studied wall is subjected to both convective heat transfer and moisture flux ... Read More

Quantification of Porosity Changes Due to Precipitation of Cement Materials with iCP

D. Sampietro [1], E. Abarca [1], M. Bayer [1], S. Jordana [1], J. Molinero [1], T. Tanaka [2], S. Hashimoto [2], T. Iwatsuki [3], H. Onoe [3], H. Saegusa [3]
[1] Amphos 21 Consulting, Barcelona, Spain
[2] Obayashi Corporation, Tokyo, Japan
[3] Japan Atomic Energy Agency, Gifu, Japan

The Japan Atomic Energy Agency (JAEA) is carrying out an URL (Underground Research Laboratory) project in Mizunami city, central Japan. The project is a purpose-built generic URL project that is planned for a scientific study of the deep geological environment in fractured crystalline ... Read More

Using COMSOL Multiphysics to Model Crust Development at the Surface of Whole Beef Meat Subjected to Hot Air Jet

J. Sicard [1], S. Portanguen [1], C. Chevarin [1], A. Kondjoyan [1]
[1] INRA Auvergne-Rhône-Alpes, Saint-Genès-Champanelle, FRANCE

Crust which develops at the surface of meat leads to reactions which affect food color, flavor and safety. Whole pieces of meat are only contaminated by microorganisms at their surface. Thus intense thermal treatment can inactivate pathogenic bacteria; however the associated high ... Read More

Thermal Conductivity of Composites: How COMSOL Revealed an Omission in a Classical Paper

P. Berne [1],
[1] University Grenoble Alpes, Grenoble, France

The initial motivation for this work was to explore the relationship between the shape of particles and the thermal conductivity of nanofluids or nanocomposites containing them. Since the possibility for manufacturing exotically-shaped particles is ever growing, it was thought useful to ... Read More

Simulation of Active Underwater Cylindrical Acoustic Antenna

R. Lardat [1],
[1] Thales Underwater Systems, Sophia Antipolis, France

The simulation of a large acoustic cylindrical antenna made of numerous identical transducers is very often out of reach in terms of computational cost. Therefore the usual design procedure consist in optimizing the transducer standing alone, either in free field arrangement or sitting ... Read More

COMSOL Multiphysics® for Building Energy Simulation (BES) Using BESTEST Criteria

A.W.M. (J.) Van Schijndel [1], D. P. M. Jacobs [1],
[1] Eindhoven University of Technology, Eindhoven, Netherlands

Pioneering Computational Models for the Built Environment Energy performance is becoming more important in the build environment. With better insulated buildings, the possibility of moisture problems and thermal bridges increases. There for, it is not only important to determine the ... Read More
