D. Malomo [1], V. Varano [2],
[1] DICEA, University of Rome, Italy
[2] LAMS, University of Rome, Italy

The "Lithic Hypar" research is based on the mechanical analysis of an innovative reinforced stone's structure, architecturally designed by Prof. Fallacara, University of Bari (Italy): the headquarters entrance portal of the French company SNBR (Société Nouvelle Batiment Régional) located in Troyes (France), the realization of which is planned for October 2015. The main idea of this lithic ...

Drop Simulation of Disposable Elastomeric Pump Using COMSOL Multiphysics® Software

R. Kapuganti [1], S. Anbazhagan[1],
[1] HCL Technologies, Chennai, India.

Drop test simulation is one of the important tool used for the impact behaviour study of electronic components. It identifies the flaws in design. The reliability and performance of electronic consoles after the drop is a major concern. Devices are expected to continue functioning after suffering a drop. The model is allowed to fall freely due to gravity load application. Drop test standard ...

Design and Simulation of MEMS Based Gyroscope for Vestibular Prosthesis

The primary function of the vestibular system is to provide the brain with information about the body\'s motion and orientation. The absence of this information causes blurred vision and spatial disorientation, vertigo, dizziness, imbalance, nausea, vomiting, and other symptoms often characterize dysfunction of the vestibular system. Our aim is to design vestibular prosthesis using COMSOL ...

Simulation of Microstructured Rolling-Sliding Contacts - new

M. Weschta[1], S. Tremmel[1], S. Wartzack[1]
[1]Engineering Design, Friedrich-Alexander-University Erlangen-Nürnberg (FAU), Erlangen, Bavaria, Germany

To reduce friction in lubricated tribological contacts, the surfaces of the contacting bodies can be microstructured to improve lubricating conditions. For lower loaded contacts this approach has already reached industrial applications, e.g. the piston-liner contact. For higher loaded contacts the effects are currently in basic research. Elastic deformation in the contact area plays an important ...

Simulation of a Thermoelectric Spiral Structure

[1] Computer, Electrical and Mathematical Sciences and Engineering (CEMSE), King Abdullah University of Science and Technology (KAUST), Thuwal, Saudi Arabia
[2] The University of British Columbia, School of Engineering, Okanagan Campus, Canada

Energy efficiency and harvest, speed and performance, flexibility and portability are key elements for innovation in the current consumer electronics markets. Thermoelectric Generators can convert energy from heat gradients into electricity. Every source of heat from an electronics device can potentially be used as a source of energy. This generators have the advantage of: being silent, compact, ...

COMSOL Multiphysics® Software: Simplifying Workflow and Promoting Innovations in Nuclear Engineering at ORNL

P. K. Jain [1], J. D. Freels [1],
[1] Oak Ridge National Laboratory, Oak Ridge, TN, USA

At Oak Ridge National Laboratory (ORNL), COMSOL Multiphysics® software has become a preferred software for certain multiphysics applications in nuclear engineering. This presentation will highlight some of the ongoing activities in the following areas: (1) Highly enriched uranium (HEU) to low enriched uranium (LEU) conversion of the High Flux Isotope Reactor (HFIR), (2) New and improved safety ...

Analysis of Cost Effective Vertical Axis Wind Turbine (CEVAWT)

H. Shaikh[1], A. Arjun[1], R. Kumbhar[2]

[2]WIL Walchandnagar, Pandharpur, Maharashtra, India

Wind turbines are the conventional type of energy source. The main focus of this work is the analysis and fabrication of cost effective VAWT. Cost of the turbine is reduced by low cost material and minimizing its total weight. There are two main types of the wind turbines i.e. Horizontal Axis Wind Turbine and Vertical Axis Wind Turbine. Savonious VAWT is preferable for energy generation, because ...

[1] FATEB, Telêmaco Borba, PR, Brazil

The liquid food product packaging are today predominantly made with board LPB type board (Liquid Packaging Board) composite formed by board, which offers mechanical strength, polyethylene, constituent responsible for protection against the passage humidity, and aluminum foil, which helps protect against oxygen flow. On the day, paper and board are words used as synonyms for each other. ...

Finite Element Modeling of Dispersion and Thermal Noise in Whispering-Gallery Mode Cavities

N. M. Kondratiev [1], M. L. Gorodetsky [1]
[1] Russian Quantum Center (RQC), Moscow, Russia

This work is dedicated to exact numerical modeling of modal dispersion and thermal noise in arbitrary cylindrical symmetric WGM structure. We develop a method and compare the results with experimental data from literature. We show that the real form of the resonator makes small influence on the thermorefractive noise spectrum and old infinite-space formula is quite universal. The modelled ...
