Simulation of Acoustic Wave-Structure Interaction in a Quarter Wavelength Tube Energy Harvester

L. Melander [1], J. H. You [1],
[1] University of St. Thomas, St. Paul, MN, USA

An acoustic energy harvesting system at low frequency (~200 Hz) using lead zirconate titanate (PZT) piezoelectric cantilever plates placed inside of a quarter-wavelength straight-tube resonator has previously been studied using COMSOL and verified experimentally. When an incident ... 詳細を見る

RF NEMS Magnetoelectric Sensor Simulation and Demonstration

H. Lin [1], N. Sun [1], N. X. Sun [1],
[1] W.M. Keck Laboratory for Integrated Ferroics, ECE Department, Northeastern University, Boston, MA, USA

RF NEMS Magnetoelectric (ME) Sensor with a ferromagnetic (FeGaB)/ piezoelectric (AlN) thin film heterostructure is simulated, fabricated and measured in this work. To analyze the response of the ME structures, the coupling between the magnetic, elastic and electric field in the two ... 詳細を見る

Thermoviscous Acoustics – Piezoelectric Modeling and Simulation of Surface Acoustic Wave Devices

V. M. Dhagat [1], P. Dufilie [2],
[1] University of Connecticut, Mansfield, CT, USA
[2] Phonon Corporation, Simsbury, CT, USA

New drug discovery and development is costly; of all compounds investigated for use in humans, only a small fraction is approved for treatments around the world. The pharmaceutical industry has started switching from molecular drugs to protein-based drugs due to high specificity, ... 詳細を見る

Modeling, Simulation, and Optimization of Piezoelectric Bimorph Transducer for Broadband Vibration Energy Harvesting in Multi-Beam and Trapezoidal Approach

N. Chen [1], V. Bedekar [1],
[1] Department of Engineering Technology, Middle Tennessee State University, Murfreesboro, TN, USA

The objective of the research is to design a broadband energy harvester device through the multi-beam approach and non-linear trapezoidal geometry approach. The performance of two piezoelectric PZT-PZN polycrystalline ceramic composition samples are simulated in COMSOL Multiphysics®, and ... 詳細を見る

Time Domain Construction of Acoustic Scattering by Elastic Targets Through Finite Element Analysis

A. Gunderson [1], B. Simon [1], A. Bonomo [1], M. Isakson [1],
[1] Applied Research Laboratories, University of Texas - Austin, Austin, TX, USA

Finite element models for acoustic scattering from three dimensional underwater elastic objects, calculated in the frequency domain, are transformed to the time domain through Fourier synthesis using COMSOL Multiphysics®. The time domain mirrors the way in which experimental scattering ... 詳細を見る

Numerical Modeling and Verification of Acoustic Streaming Induced by Ultrasonic Treatment

D. Rubinetti [1], D. A. Weiss [1], J. Müller [2], A. Wahlen [2],
[1] Institute of Thermal and Fluid Engineering, University of Applied Sciences Northwestern Switzerland, Windisch, Switzerland
[2] Institute of Product and Production Engineering, University of Applied Sciences Northwestern Switzerland, Windisch, Switzerland

Acoustic streaming (AS) describes a physical phenomenon where an oscillating sound emitter induces a steady fluid motion. Metal processing industry applies this treatment for grain morphology adjustments during the solidification of metal. Improvement and further development of this ... 詳細を見る

Analysis of High-Frequency Thermoacoustic Instabilities in Lean, Premixed Gas Turbine Combustors

F. Berger [1], T. Hummel [1], P. Romero [1], M. Schulze [1], B. Schuermans [2], T. Sattelmayer [1],
[1] Lehrstuhl für Thermodynamik, TU München, Germany
[2] GE Power, Switzerland

Modern gas turbine systems for power generation are prone develop so-called thermosacoustic instabilities in the combustion chamber. Physically, these instabilities emerge as large amplitude pressure oscillations within the combustor, which are caused by constructive feedback ... 詳細を見る

Lumped Element Multimode Modeling of Balanced-armature Receiver with COMSOL Multiphysics® Software

Wei Sun [1],
[1] Institute of Acoustics, Tongji University, China

For the lack of higher order modes, lumped element (LE) models currently used may be insufficient to predict the system of balanced-armature receiver (BAR). We develop a LE multimode model for BAR in the frequency domain based on the techniques of mode decomposition, truncation, and ... 詳細を見る

Qingwei Liu [1], Hangjie Mo [1]
[1] Shanghai Jiao Tong University, Shanghai, China

This paper studies the application of laminate magnetoelectric (ME) material in displacement sensor. We studied the L-L block composite thanks to designed structure by coupling displacement signal with the displacement potential of ME composite. A nonlinear approximation is adapted to ... 詳細を見る

Design and Simulation of Capacitive Pressure Sensor for Condition Monitoring

S. Sushma[1], R. Surekha[1], K. J. Rudhresha[1], S. Sahu [1], S. Singh4 [1], S. L. Pinjare6 [1],
[1] Dept. of ECE, Nitte Meenakshi Institute of Technology, Bangalore, Karnataka, India.

This poster focuses on the development of a capacitive pressure sensor for condition monitoring applications. One method to measure vibrations is to mount an pressure sensor on the vibrating machinery or object and measure the pressure exerted due to vibrations. Measured pressure level ... 詳細を見る
