Application of COMSOL to Acoustic Imaging

K. Mcilhany, and J.C Hernandez
U.S. Naval Academy, Annapolis, MD, USA

Acoustic Imaging of hand movement is being studied with COMSOL and Matlab. A hardware implementation is being pursued that will be an array of 16x16 ultra-sonic speakers placed in a grid facing a similar grid of 16x16 microphones, operating at 40kHz. COMSOL is used to repeatedly ... En savoir plus

Modeling the Heat Exchange in Cavities of Building Constructions Using COMSOL Multiphysics®

J. van Schijndel[1], B. Kersten[1]
[1]Eindhoven University of Technology, Eindhoven, The Netherlands

Double walls provide stability to the structure and separate the controlled indoor climate from the outdoor fluctuating environment. In this study we want to receive more insight in the heat exchange between the walls through the cavity in between, by computer simulations and ... En savoir plus

Shape and Failure Control of Composite Laminates Using Piezoelectric Actuators

Z. Hasan
Texas A&M University, College Station, TX, USA

The present work focuses on the use of piezoelectric materials as actuators for shape control of composite laminates such as Lead Zircronate Titanate (PZT), and other piezoelectric fiber composites such as Active fiber composites (AFCs), Microfiber Composites (MFCs) which allow for ...

Analyte Capture from Liquid Samples: Size Matters

M. Weber[1], M. Reed[1]
[1]Yale University, New Haven, CT, USA

Arrays of vertical pillars, Micro Purification Chips, have been widely used for analyte capture from liquid samples [Henderson et. al, 2006], [Toner et. al, 2007], [Stern et. al, 2010]. However exact understanding of the capture efficiency mechanisms has not been previously explained. ... En savoir plus

Improving Fuel Usage in Microchannel Based Fuel Cells

P. Fodor, and J. D'Alessandro
Dept. of Physics
Cleveland State University
Cleveland, OH

In this work a miniaturized fuel cell design based on microchannels, into which the liquid fuel and oxidizer streams are fed through T shaped connectors, is optimized for improved fuel usage. This particular design exploits the laminar nature of the fluid flow at small Reynolds numbers ... En savoir plus

Finite Element Modeling of a Pulsed Eddy Current Probe for Steam Generator Tube Inspection

S. G. Mokros[1, 2], V. K. Babbar[1], T. W. Krause[1], J. Morelli[2]
[1]Department of Physics, Royal Military College of Canada, Kingston, ON, Canada
[2]Department of Physics, Engineering Physics and Astronomy, Queen's University, Kingston, ON, Canada

Steam generator (SG) tubes in CANDU® nuclear reactors can lose efficiency in the presence of corrosion and its by-products. Condition monitoring of support structures could help direct maintenance activities and thereby increase SG tube lifetime. Pulsed eddy current (PEC) has been ... En savoir plus

Development of MEMS-based Pressure Sensor for Underwater Applications

Aarthi E[1], Pon Janani S[1], Vaidevi S[1], Meenakshi Sundaram N [1], Chandra Devi K[1]
[1]PSG College of Technology, Coimbatore, Tamil Nadu, India

Blind cave fish are capable of sensing flows and movements of nearby objects even in dark and murky water conditions with the help of arrays of pressure-gradient sensors present on their bodies called lateral-lines. To emulate this functionality of lateral-lines for autonomous underwater ... En savoir plus
