Relativistic Quantum Mechanical Wave Functions for Fermion Particles in Electric or Magnetic Fields

A. J. Kalinowski [1],
[1] Consultant / East Lyme, CT, USA

INTRODUCTION: The Dirac equation is employed in particle physics and historically gave the first combined unification of quantum mechanics and relativity theory by introducing a four component wave function Ψi. This wave function described the behavior of fermion type particles (e.g. ... Mehr lesen

Process Intensification Efforts towards Efficient, Modular, Solar-Thermochemical Production of Liquid Fuels

L. Freiberg [1], M. Coblyn [1], G. Jovanovic [1], N. AuYeung [1],
[1] Oregon State University, Corvallis, OR, USA

Concerning the reduction of fossil-energy use from industrial processes, power generation and transportation, concentrated solar power from dish reflectors is well suited for driving highly endothermic reactions that valorize CO2 and/or light hydrocarbons. In this study, a directly ... Mehr lesen

Numerical Analysis of a LiFePO4/Graphite Lithium-ion Coin-cell Battery

L. Tong [1],
[1] Keisoku Engineering System Co., Ltd., Chiyoda-ku, Tokyo, Japan

Electric vehicles (EVs) powered by rechargeable lithium-ion batteries (LIBs) have been developed as a replacement for the conventional internal-combustion-engine automobiles. Research has been yielding a stream of improvements to the traditional LIB technology, focusing on energy and ... Mehr lesen

Multiphysics Simulation of an Ultrasonic Piezoelectric Motor

P. Carvalho [1], C. Nycz [1], K. Gandomi [1], G. Fischer [1],
[1] Worcester Polytechnic Institute, Worcester, MA, USA

Operation in strong magnetic fields, vacuum or high precision positioning has often surpassed the limits of traditional actuators. Piezoelectric motors provide a suitable alternative in these applications where non-ferromagnetic based construction or low inertia may be required. We ... Mehr lesen

Modeling the Electric Double Layer in Finite Electrolyte Solutions

J. C. Woehl [1],
[1] University of Wisconsin - Milwaukee, Milwaukee, WI, USA

While electric double layers play a crucial role in many biophysical processes involving charged molecular species (such as proteins and DNA), they are often a limiting factor in technological applications where charged conductors are brought in contact with electrolyte solutions. ... Mehr lesen

Modeling a Concentrated Solar Thermal Collector for Methane Dry Reforming

S. Verma [1], N. Hotz [1],
[1] Duke University, Durham, NC, USA

Hydrogen has great potential to be the fuel of the future through utilization in fuel cells, but it is rarely found naturally and must be produced in energy-intensive processes. Steam reforming, the process of heating natural gas and steam in the presence of a catalyst to drive a ... Mehr lesen

Mechanistic Understanding of Food Microbiological Safety: Multiphase Transport Through a Leaf Stomate During Vacuum Cooling

M. Ranjbaran [1], A. K. Datta [1],
[1] Cornell University, Ithaca, NY, USA

Vacuum cooling is a common unit operation in the leafy greens industry and is considered as a very efficient approach to extend the shelf-life of fresh produce. However, during this popular process, bacteria can internalize into the produce. This emphasizes the need for better ... Mehr lesen

Magnetic Control of Deformation of a Ferrofluid Droplet in Simple Shear Flow

C. Wang [1], M. R. Hassan [1],
[1] Department of Mechanical and Aerospace Engineering, Missouri University of Science and Technology, Rolla, MO, USA

This study investigates the effect of uniform magnetic field on the deformation of a ferrofluid droplet in a two dimensional (2D) simple shear flow by means of numerical simulation. The magnetic field is applied in a perpendicular direction to the flow direction. A numerical scheme ... Mehr lesen

Load Noise Calculation of a Three-Phase Power Transformer

C. S. Lin [1],
[1] Pitotech. Co Ltd., Changhua City, Changhua, Taiwan

Vibrations and noise of high power transformers have attracted considerable experimental and theoretical interests over last few years [1, 2]. For such transformers operating under high voltage (~ 100 kV) and power (~ 100 MVA), noise generated is significantly attributed to load noise ... Mehr lesen

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 ... Mehr lesen
