Hot Cracking in Nb-Si Alloys

I. Y. Fernando [1],
[1] University of Leicester, Leicester, UK

Introduction With the vast development in the aerospace industry it is inevitable that currently used materials such as Nickel based super alloys will soon reach its peak performance. Hence developing alternative materials with similar properties that could be enhanced further is ... Read More

Knowledge and Skills Acquisition via a “Parallel” Problem Solving Approach

J. R. Sanders [1], S. N. Jorgensen [1],
[1] Tennessee Technological University, Cookeville, TN, USA

To be competitive in today’s workforce, students in STEM undergraduate programs are expected to develop problem-solving skills. Often, this occurs through guidance and practice in the form of assignments, labs, experiential learning opportunities, teamwork, and other means. The concept ... Read More

Ultrasonic Power Delivery Through a Steel Wall - Water Interface

P. Moilanen [1], A. Salmi [1], E. Haeggström [1],
[1] Electronics Research Laboratory, Division of Materials Physics, Department of Physics, University of Helsinki, Helsinki, Finland

This simulation study analyzed ultrasonic power delivery by low-frequency (20-50 kHz) high-power ultrasonic actuation into fluid through a steel wall. The Acoustic-Piezoelectric Interaction, Frequency Domain interface of the COMSOL Acoustics Module were employed for this study. The ... Read More

Improving the Performance of Instant-Fit Earpieces by Making Use of FE-Analyses

D. Stauske [1], S. Kahms [1],
[1] Institute of Dynamics and Vibration Research, Hannover, Lower Saxony, Germany

According to a report conducted by the World Health Organization (WHO), more than 466 million people suffer from hearing loss. Conventional hearing aids are sufficient for most patients, being constantly further developed and optimized - connecting the service of the hearing aid to the ... Read More

Graphene-Assisted Lipid Bilayer: A Synthetic Cell Model

E. Lacatus [1],
[1] Polytechnic University of Bucharest, Romania

Bio-compatibilized G/GO/RGO composite structures with embedded stearic acid on a bilayer structure model, biomimicking the cellular lipid bilayer are introduced through successive models. The solvent accessible surface of the models (van der Waals surface) and the related MD values were ... 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

Simulation of Magnetically Driven Peristaltic Pumps for Microfluidic Applications

L. Gritter [1], J. Crompton [1], K. Koppenhoefer [1], P. Nath [2]
[1] AltaSim Technologies, Columbus, OH, USA
[2] Applied Modern Physics, Los Alamos National Lab, Los Alamos, NM, USA

Microfluidic technologies can enable laboratory processes to be packaged in miniaturized and automated systems, allowing these processes to be performed with hand-held devices outside a laboratory environment. The practical usefulness of these “lab on a chip” systems has often been ... Read More

Simulation as Various Operating Condition for High Temperature Magnesium Hydride Reactors

D.Y. Shin, T.E. Kim, J.Y. Lee
Altsoft Inc., Seoul, South Korea

Magnesium hydride (MgH2) has been one of the most promising hydrogen storage methods that can be applied to commercial hydrogen energy systems due to magnesium’s safety, low cost, and excellent storage capacity for hydrogen, compared to other reversible metal hydrides. But hydrogen ... Read More
