Effect of Duty Cycle Variation on Acoustic Pressure Field Simulation in an Ultrasound Bioreactor

A. Rahimi [1], J. Crapps [1], N. Case [1]
[1] Biomedical Engineering, Saint Louis University, Saint Louis, MO, USA

Daily application of a low intensity pulsed ultrasound (LIPUS) regimen has been shown to have positive effects on bone fracture healing. Although LIPUS treatment can induce cellular responses supporting bone repair, the underlying mechanisms are not well understood. Further in vitro ... Read More

Dissolution Modeling of Uniform Aqueous Droplets in Two-Phase Flow in a Microfluidic Device

[4] Shriners Hospitals for Children - Boston, Boston, MA, USA

Safe preservation of mammalian cells for long term is essential for medical and pharmaceutical industries. Cryopreservation by conventional slow freezing and by vitrification below freezing temperatures are the most effective biopreservation methods compared to in vitro culture at ... Read More

Diffusive Transport in a Deep Geological Repository for Used Nuclear Fuel

M. Krol [1], S. Briggs [2],
[1] York University, Toronto, ON, Canada
[2] Nuclear Waste Management Organization, Toronto, ON, Canada

The Nuclear Waste Management Organization (NWMO) is developing a deep geological repository as part of Adaptive Phased Management (APM), Canada’s plan for the long-term management of used nuclear fuel. The repository is a multiple barrier system to protect people and the environment. To ... 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

Design of an Electro-Osmotic Microfluidic Mixer

T. Eppes [1], I. Milanovic [1], S. Keilich [1],
[1] University of Hartford, West Hartford, CT, USA

This paper explores the performance of a microfluidic mixer that uses a sinusoidal electric field to accelerate the diffusion process between two Newtonian liquid species in an electrolytic solution. The 2D model was developed using the Microfluidics module in the COMSOL Multiphysics® ... Read More

Computational Fluid Dynamics Modeling of the NASA Titan Wind Tunnel

S. E. H. Sakimoto [1, 2], D. M. Burr [3], S. L. Sutton [3],
[1] Space Science Institute, Boulder, CO, USA
[2] Department of Geology, University at Buffalo, Buffalo, NY, USA
[3] Department of Earth and Planetary Sciences, University of Tennessee - Knoxville, Knoxville, TN, USA

The equatorial region of Titan, the largest satellite of Saturn, has extensive expanses of aeolian dunes revealed in synthetic aperture radar (SAR) images and suggested to be composed of organics or organic-coated water ice. The dunes are among the youngest surface features and appear to ... Read More

CdS Thin Film Transistor Threshold Voltage Shift Investigation

W. Wondmagegn [1],
[1] Frostburg State University, Frostburg, MD, USA

A threshold voltage shift of CdS Thin Film Transistor is studied using the COMSOL Multiphysics® software's Semiconductor Module. Drift-diffusion (DD) simulation model is used in which the basic equations used are similar to those used for a single-crystal device except that traps and ... 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

Augmentor Combustion Instability with the COMSOL Multiphysics® software

V. G. Shaw [1], J. D. Clabbers [1], E. J. Gutmark [1],
[1] University of Cincinnati, Cincinnati, OH, USA

Combustion instability has been a serious issue through the developmental history of gas turbine augmentors. When heat release rate oscillations occur in phase with resonant chamber acoustic modes, a feedback cycle is formed in which the strength of local heat release rate and chamber ... 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
