Fluid Structure Interaction of Arch Dam on Full Reservoir Level under Seismic Loading

R. Manikandan[1], R. Jayashiri [1], R. Indumathi [1], J. Archana [1],
[1] Dhirajlal Gandhi College of Technology, Salem, Tamil Nadu, India

The Finite Element Model is analyzed with impounded water considering appropriate boundary conditions between the water & the upstream face of the dam .The fluid on the upstream side is considered to be incompressible, inviscous, and irrotational. Here the effect of fluid ... En savoir plus

Inlay Fixed Partial Denture Framework 3-D Structural Integrity Validation Using COMSOL Multiphysics^®

T.M.R. Alho[1]

[1]Department of Electrical Engineering and Automation, University of Vaasa, Vaasa, Finland

Manual manufacturing of inlay fixed partial denture frameworks by metal casting can take hours of dental practitioners work time. This paper introduces 3-D simulations of premanufactured inlay fixed partial denture framework assembled from laser cut sheet metal parts. The study gives a ... En savoir plus

Support-Q Optimisation of a Trapped Mode Beam Resonator

T. H. Hanley[1], H. T. D. Grigg[1], B. J. Gallacher[1]
[1]Newcastle University, Newcastle-Upon-Tyne, UK

Introducing a disorder into a finite periodic oscillatory system induces the presence of a 'trapped mode': a mode in which the displacement field is localised to the region of the disorder. A main inhibitor to MEMS resonators achieving a high quality (Q) factor is energy radiation ... En savoir plus

Optimization of Device Geometry of a Fully-Implantable Hearing Aid Microphone

A. Dwivedi [1], G. Khanna [1],
[1] National Institute of Technology Hamirpur, Himachal Pradesh, India

The hearing impairment is affecting more than 360 million people all over the world.In India alone, 63 million people suffer from the significant auditory loss. Conventional hearing aids suffer from reliability, practicality and social stigma concerns. The totally implantable devices ... En savoir plus

COMSOL® Analysis for Duct Acoustic

M. M. Ghulam [1], E. J. Gutmark [1],
[1] Aerospace Department, University of Cincinnati, Cincinnati, OH, USA

COMSOL analysis of the acoustic modes of two different Combustion Wind Tunnel Facility’s test sections was conducted in this project. The test sections are rectangular ducts, therefore the mathematical expressions to predict the longitudinal and transverse modes inside a tube were used ... En savoir plus

Simulation of Acoustic Energy Harvesting Using Piezoelectric Plates in a Quarter-Wavelength Straight-Tube Resonator

B. Li[1], J.H. You[1]
[1]Southern Methodist University, Dallas, TX, USA

An acoustic energy harvesting mechanism at low frequency (~200 Hz) using lead zirconate titanate (PZT) piezoelectric cantilever plates placed inside a quarter-wavelength straight-tube resonator has been studied using COMSOL Multiphysics 4.3 and compared with experimental data. When the ... En savoir plus

Modeling, Simulation, and Control of Dual Electromagnet Active Magnetic Levitation

A.K. Pi?at[1]
[1]AGH University of Science and Technology, Kraków, Poland

Introduction: The dual electromagnet configuration of Active Magnetic Levitation system (AML) where the electromagnets are locate opposite to each other, constitutes and single axis of the Active Magnetic Bearing. The same configuration can be used to test the single electromagnet AML ... En savoir plus

Mathematical Model for Prediction of Transmission Loss for Clay Brick Walls

J. Ratnieks[1], A. Jakovics[1], J. Klavins[1]
[1]Laboratory for Modeling Technological and Environmental Processes, University of Latvia, Riga, Latvia

A 2D numerical model for determination of sound reduction index is set up in this work. Results are in good agreement in middle and high frequency range when using solid structure approximation. Results are compared with experiment. En savoir plus

Impact Simulation of Extreme Wind Generated Missiles on Radioactive Waste Storage Facilities

G. Barbella[1]
[1]Sogin SpA, Roma, Italy

The structural design of temporary storage facilities for radioactive waste generally requires the fulfillment of highly severe performance criteria if compared to conventional buildings. This work focuses on the study of the behavior of a steel door subject to the impact of extreme wind ... En savoir plus

3D Acoustic Streaming Field in High-Intensity Discharge Lamps

B. Baumann[1], J. Schwieger[1], M. Wolff[1], F. Manders[2], J. Suijker[2]
[1]Hamburg University of Applied Sciences, Hamburg, Germany
[2]Philips Lighting, Turnhout, Belgium

High-intensity discharge lamps will in the foreseeable future be important light sources despite a growing market share of LEDs. Cost and energy efficient high frequency (300 kHz) operation is hampered by the excitation of acoustic resonances inside the arc tube, which results in low ... En savoir plus
