Flotation Height in 'Air Hockey' Spatial Atomic Layer Deposition

J. Grasso [1], B. Willis [1],
[1] Department of Chemical and Biomolecular Engineering, University of Connecticut, Storrs, CT, USA

Atomic layer deposition(ALD) is one proven method to deposit ultra-thin films. ALD is advantageous for its atomic-level thickness control and conformity; leading to high quality films. Slow deposition rates for conventional ALD contribute to the impracticality of utilization of this ... Read More

COMSOL® Modeling and Tensile Loading of Aluminum Material Test Samples

J. L. Palladino [1],
[1] Trinity College, Hartford, CT, USA

Material test samples are commonly subjected to tensile testing, with an extensometer used to measure changes in length of the material to determine strain. Lacking an extensometer, strain gages were used to measure longitudinal and transverse strain, with the location and magnitudes of ... Read More

COMSOL Multiphysics® as a Tool for Biomedical Engineering Students to Harness Physical Processes

J. Bush [1],
[1] Old Dominion University, Norfolk, VA, USA

The field of Biomedical Engineering is expanding at an exponential rate. As we began to unravel clues about our complex biological vessels, we uncovered more questions than answers. Our collective curiosity has led biomedical engineering into a broadening field by study of physiological ... Read More

Computational Fluid Dynamic Study of Fixed Bed Reactor of Hydrotreating of Vegetable Oil

N. Casillas [1], L. Olivo [1],
[1] Instituto Politécnico Nacional, Ciudad de México, México

Hydrodynamics of fixed bed reactors involve complex interactions of gas and liquid phases with packed solids. Such complex interactions manifest in different flow regimes occurring in trickle-bed reactors. A comprehensive CFD model was developed to predict measured hydrodynamic ... Read More

Catalytic Oxidative Dehydrogenation of Propane to Propylene

E. B. Ledesma [1],
[1] University of St. Thomas, Houston, TX, USA

Propylene is the second most important olefin and the second largest volume industrial chemical produced globally. In 2015, the global demand for propylene was about 94 million metric tons. The largest use for propylene is the production of polypropylene, consuming 67% of propylene ... Read More

Analyzing Electromagnetic Modes of Integrated Busbars Implemented as Printed Circuit Boards (PCB)

A. Pokryvailo [1],
[1] Spellman High Voltage Electronics Corp., Hauppauge, NY, USA

This report addresses design of a PCB intended for use as a busbar integrated with multiple DC-link (rail) capacitors in a high power inverter. The geometry and current ratings are typical of a 50 kW unit operating at 60kHz in an intermittent mode. First, circuit aspects are analyzed. ... Read More

A Multi-phase Heat Transfer Model of Cooling Lava

M. E. Rumpf [1], K. Williams [1], L. Kestay [1],
[1] Astrogeology Science Center, U.S. Geological Survey, Flagstaff, AZ, USA

Field observations suggest that two-phase "heat-pipe" processes are active around magmatic intrusions. We are numerically testing the viability of this process around a volcanic sill, embedded in wet sediment. The model focuses on the heat transported by water in the vapor and liquid ... Read More

A 3D Simulation of the Diffusion Profile of Brain Derived Neurotrophic Factor in the Inner Ear Using the COMSOL Multiphysics® software

S. Bharadwaj [1], A. Oleksijew [1], J. Fernandez [2], C. Miller [1], K. Coots [1], K. Nella [1], H. T. Chang [1], C. P. Richter [1, 3], J. Kessler [1], A. Matsuoka [1]
[1] Feinberg School of Medicine, Northwestern University, Chicago, IL, USA
[2] Department of Chemical Engineering, Northwestern University, Chicago, IL, USA
[3] Resonance Medical, LLC., Chicago, IL, USA

Sensorineural hearing loss, which is the most common type of hearing impairment, originates from damaged inner ear nerves. However, this can be treated in many cases by regenerating the synaptic connections between the extant Spiral Ganglion Neurons (SGNs) and transplanted human stem ... Read More

3D Unsteady CFD Simulation of Seasonal Solar Thermochemical Heat Storage System for Buildings

W. Yaïci [1], E. Entchev [1],
[1] CanmetENERGY Research Centre, Natural Resources Canada, Ottawa, ON, Canada

Solar energy storage has been an extensive research topic among the several thermal energy applications over the past three decades. Thermal energy storage (TES) systems in general, improve the energy efficiency of systems and sustainability of buildings by reducing the mismatch between ... Read More

Using the COMSOL Multiphysics® software for simulation of TEGs for Waste Thermal Energy Harvesting

L. Howard [1], D. Tafone [2], D. Grbovic [1], A. Pollman [1],
[1] Naval Postgraduate School, Monterey, CA, USA
[2] Ramapo College of New Jersey, Mahwah, NJ, USA

Navy systems, such as turbine engines, produce large quantities of thermal energy. This energy is a byproduct of the work produced by the engine during operation and is typically rejected to its surroundings. The temperature difference between the turbines and the ocean is substantial ... Read More
