Numerical Modeling and Performance Optimization Study of a Dehumidification Process in Nuclear Waste Storage

P. Geraldini[1]
[1]Sogin Spa, Rome, Italy

One of the main parameters to consider during the nuclear waste storage design phase is the drum corrosion risk. The humid-air corrosion models available in literature predict that, for carbon steel, the phenomena start to become appreciable for relative humidity (RH) values close to ... En savoir plus

A Study into the Acoustic and Vibrational Effects of Carbon Fiber Reinforced Plastic as a Sole Manufacturing Material for Acoustic Guitars

J. O'Donnell[1], G. McRobbie[1]
[1]University of the West of Scotland, Paisley, Scotland, United Kingdom

This study will research a modern design of acoustic guitar by analysis of the vibrational modes. The guitar that will undergo testing has been provided by Emerald Guitars and is solely constructed using Carbon Fiber Reinforced Plastic (CFRP). With the use of COMSOL Multiphysics© the ...

Design and Simulation of an Orbiting Piezoelectric MEMS Gyroscope Based on Detection of Phase-Shift Signals

S. Gorelick[1], J. R. Dekker[1], B. Guo[1], H. Rimminen[1]
[1] VTT Technical Research Centre of Finland, Espoo, Finland

The feasibility of phase-sensitive detection of angular-rates using bi-directional orbiting piezoresonators suspended by thick annular springs with thin-film aluminium nitride piezoactuators on top of them was investigated. The ring-shaped flexures are more suitable for supporting the ... En savoir plus

Full System Modeling and Validation of the Carbon Dioxide Removal Assembly

R. F. Coker[1], J. Knox[1]
[1]NASA Marshall Space Flight Center, Huntsville, AL, USA

The Atmosphere Revitalization Recovery and Environmental Monitoring (ARREM) project was initiated in September of 2011 as part of the Advanced Exploration Systems (AES) program. Under the ARREM project, testing of sub-scale and full-scale systems has been combined with multiphysics ... En savoir plus

Design and Simulation of Unimorph Piezoelectric Energy Harvesting System

E. Varadarajan[1], M. Bhanusri[2],
[1]Research and Innovation Centre (RIC), IITM Research Park, Chennai, Tamil Nadu, India
[2]Department of Physics, Indian Institute of Technology (IIT) Madras, Chennai, Tamil Nadu, India

In this paper we made an attempt to maximize the power output in the different piezoelectric materials in a unimorph cantilever beam configuration. In this research, a macro scale unimorph piezoelectric power generator prototypes consists of an active piezoelectric layer, stainless steel ... En savoir plus

Modeling and Simulation of High Permittivity Core-Shell Ferroelectric Polymers for Energy Storage Solutions

N. Badi[1], R. Mekala[1]
[1]University of Houston, Houston, TX, USA

The dielectric properties of ferroelectric PVDF polymer embedded core-shell (Al-Al2o3) nanoparticle is simulated using COMSOL Multiphysics® software. Significant increase in electrical permittivity of the composite at percolation threshold (K = 2800) is achieved when compared to ... En savoir plus

Mathematical Model of Blood Flow in Carotid Bifurcation

E. Muraca[1], V. Gramigna[1], and G. Fragomeni[1]
[1]Department of Experimental Medicine and Clinic, Magna Graecia University of Catanzaro, Catanzaro, Italy

The goal of this research is to provide the medical staff with a numerical system assessment of wall shear stress in carotid bifurcation. Through this model, it will be fundamental to investigate the stress state properties of the surface in contact between the plaque and the artery, and ... En savoir plus

Modelling the Wall Vibrations of Brass Wind Instruments

V. Chatziioannou, and W. Kausel
Institute of Music Acoustics
University of Music and Performing Arts
Vienna, Austria

The vibration of the walls of brass wind instruments has been a subject of study in the field of musical acoustics throughout the last decades. The amplitude of such vibrations, stimulated by the oscillating air pressure inside the instrument bore, is very small compared to the ... En savoir plus

MEMS-Based Microdroplet Generation with Integrated Sensing

P. Ben-Tzvi, and W. Rone
George Washington University
Washington, DC

This paper presents model development and simulation results for a microdroplet generator capable of internally measuring the volume of dispensed droplets. The system’s integrated sensing is enabled by storing compressible gas adjacent to the dispenser’s liquid reservoir. During ... En savoir plus

On the Simulation of Electromagnetic Forming Process of a Tube using Multiphysics Software

S. Gawade[1], P. P. Date[2], and S. B. Sharma[1]
[1]Production Engineering. Dept. SGGS IE&T, Nanded, India
[2]Mechanical Engineering. Dept, IIT, Bombay, India

Electromagnetic forming (EMF) is a typical high speed forming process using the energy density of a pulsed magnetic field to form workpieces made of metals with high electrical conductivity like e.g. aluminium. This forming process can be very advantageous as compared to conventional ... En savoir plus
