Extraction of Electrical Equivalent Circuit of One Port SAW Resonator Using FEM-based Simulation

A. K. Namdeo [1], H. B. Nemade [1],
[1] Department of Electronics and Electrical Engineering, Indian Institute of Technology Guwahati, Guwahati, Assam, India

The paper presents a method of extraction of electrical equivalent circuit of a one port surface acoustic wave (SAW) resonator from the results of simulation based on finite element method (FEM) using COMSOL Multiphysics software. A one port SAW resonator consists of large number of ... Read More

A MEMS Condenser Microphone for Consumer Applications

S. L. Pinjare, V. S. Nagaraj, S. N. Savitha, S. Kesari, M. S. Sagar, and K. R. Roshan
Nitte Meenakshi Institute of Technology

The MEMS microphone is also called microphone chip or silicon microphone. The pressure sensitive diaphragm is etched directly into a silicon chip by MEMS techniques and is usually accompanied with integrated preamplifier. Most MEMS microphones are variants of the condenser microphone ... Read More

Using Multiphysics to Quantify Leakage Rates in New and Rehabilitated Sewer and Water Pipes

C. Hansen [1],
[1] Electro Scan Inc., Sacramento, CA, USA

Traditionally, municipal sewer and water agencies have relied on acoustic data loggers and closed-circuit television cameras to inspect pipes for leaks. In addition, the same legacy techniques have been used to certify new and rehabilitated pipes as watertight. Unfortunately, visually ... Read More

Damping in Dense Gas Acoustic Structure Interaction

J. P. M. Smeulers [1], H. P. Pereboom [1], N. González Díez [1],
[1] TNO, Delft, The Netherlands

Large centrifugal compressors, which are commonly applied in the oil and gas and in the process industry, may fail due to vibrations of the impeller. These vibrations are induced by pressure pulsations in a compressor stage. These vibrations can be especially strong in so-called dense ... Read More

Parametric Simulation of PZT Diameter to Hole Ratio for Optimized Membrane Displacement

A. Arevalo [1], D. Castro [1], D. Conchouso [1], I. G. Foulds [2]
[1] Computer, Electrical and Mathematical Sciences and Engineering (CEMSE), King Abdullah University of Science and Technology (KAUST), Saudi Arabia
[2] The University of British Columbia, School of Engineering, Okanagan Campus, Saudi Arabia

For our simulation we used the Piezoelectric Devices interface. The structure was set with (clamped) fix constraint boundaries to both ends. The bottom electrode was set to be the ground for the electrostatic physics and the top electrode was set to be a Terminal with potential of 10V. A ... Read More

[2]Centre for Nanobioscience, Agharkar Research Institute, India

This paper presents a design of polymer based micro heater operating in the temperature range of 200- 250°C which could be operated at low voltage (battery operated). The micro heater has been designed and simulated using COMSOL 4.1, FEM simulation tool. Simulation was performed for ... Read More

Prototype Probe Development for Liquid Injection Shutdown System Tube Gap Detection by Remote Field Pulsed Eddy Current Technique

T. V. Shyam[1], B. S. V. G. Sharma[1], J. N. Kayal[1]
[1]Bhabha Atomic Research Centre, Trombay, Mumbai, India

Pressurised Heavy Water Reactors (PHWR) play a prominent role in contributing power for the Nuclear Energy Programme in India. In 540MWe type PHWR reactors, there are horizontally placed Liquid Injection Shutdown System (LISS) tubes for injecting poison into the moderator to clamp down ... Read More

Simulation of the Geometric Design Parameters’ Impact on the Performance of EHD Ion-Drag Micropump

M. Badran [1],
[1] Future University in Egypt, New Cairo, Egypt

A two-dimensional numerical simulation study has been performed to model an electrohydrodynamic (EHD) micropump. The emphasis of this study was on simulating the effect of the different geometric design parameters on the micropump pressure head and volume flow rate. The simulated design ... Read More
