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

Simulator for the Development of Electromagnetic Heart Assist Devices

D. G. Hurd [1],
[1] Iowa State University, Ames, IA, USA

Every year, in the United States alone, more than 40,000 infants are born with congenital heart defects (CHD) and an additional 550,000 adults are diagnosed with heart failure. Every year, $110 billion is spent on treating heart attacks and $20-39 billion on heart failure in the US. The ... Read More

Numerical Evaluation of the Polarizability Tensors of Stem Cells with Realistic 3D Shapes

S. Baidya [1], A. M. Hassan [1], B. A. Pazmiño Betancourt [2], J. F. Douglas [2], E. J. Garboczi [3],
[1] Computer Science Electrical Engineering Department, University of Missouri - Kansas City, Kansas City, MO, USA
[2] Materials Science and Engineering Division, National Institute of Standards and Technology, Gaithersburg, MD, USA
[3] Applied Chemicals and Materials Division, National Institute of Standards and Technology, Gaithersburg, MD, USA

Most of the reported studies on the electrical characteristics of biological cells assume that they have simple shapes like spheres or ellipsoids due to the lack of information about their accurate 3D shape. However, the actual shape of a cell can be quite fractal and it must be taken ... Read More

Improving Thermal Effect on Biological Tissue using Multiphysics Simulation and Shape Optimization

A. Ward [1],
[1] System Insight Engineering, Centennial, CO, USA

As minimally invasive and robotic surgical devices get smaller, designing precise energy delivery to create the desired tissue effect becomes a key component in product development. With many interdependent physical phenomena occurring simultaneously, it becomes necessary to use tools ... Read More

Evaporative Cooling in Solar Absorption Chiller

J. Ma [1], M. J. Suh [1],
[1] Sam Houston State University, Huntsville, TX, USA

Solar cooling systems based on evaporation and absorption processes have been actively studied and different mechanisms based on various refrigerants are designed and developed. Amongst these systems, a single-stage close cycle design utilizing lithium bromide salt and water (LiBr-H2O) ... Read More

Electromagnetic Simulation of Split-Core Current Transformer for Medium Voltage Applications

N. Paudel [1], V. Siddharth [1], S. Shaw [1], D. Raschka [1],
[1] ABB, Inc., Instrument Transformers & Distribution Components, Pinetops, NC, USA

In electric distribution network, current and voltage measurement for metering, monitoring, and protection & control applications is done via instrument transformers (current and voltage transformers). These measurement devices are deployed during the construction phase of the ... Read More

Development of Eddy Current Probe using FEM for Matte Level Detection in Pyrometallurgical Furnaces

A. Saleem [1], P. R. Underhill [1], D. Chataway [2], T. Gerritsen [2], A. Sadri [2], T. W. Krause [1],
[1] Department of Physics and Space Science, Royal Military College of Canada, Kingston, ON, Canada
[2] Hatch Ltd., Mississauga, ON, Canada

Pyrometallurgical furnaces are used to produce metals such as copper, nickel and platinum by the smelting process. During smelting, the undesired material components are separated from the desired metal resulting in the formation of a slag and matte/metal phase. The slag phase ... Read More

Automated Meshing of Evolving Microstructures from High-Throughput Grain Growth Simulations

M. Golt [1], E. Hernandez-Rivera [1],
[1] U.S. Army Research Laboratory, Aberdeen Proving Ground, MD, USA

Microstructure evolution simulations using the kinetic Monte Carlo algorithm and the phase field method are routinely used to model and simulate sintering and densification of ceramic and metallic materials. Understanding evolution of microstructural features is important as these are ... Read More

Analysis of Electromagnetic Fields in Urban Environments

J. Crompton [1], L. Gritter [1], S. Yushanov [1], K. Koppenhoefer [1],
[1] AltaSim Technologies, Columbus, OH, USA

Electromagnetic fields are pervasive in today’s urban environment and under certain circumstances exposure has led to safety hazards that have been reported to cause personal injury. The United States Department of Labor has reported multiple cases of electrical shock on construction ... Read More

Computational Fluid Dynamics Approach to Evaluate Electrostatic Precipitator Performance

M. Ahmadi [1]
[1] Faculty of Engineering Technology, University of Twente, Enschede, The Netherlands

Electrostatic precipitation is an extremely efficient way of filtering fine particles from the airstream. Electrostatic precipitators (ESPs) can control airborne emission without significantly slowing down the rate of flow, because of the low pressure drop across this type of filters. A ... Read More
