The Metal Patch Effect on the Microwave Heating Uniformity

Huacheng Zhu [1], Qian Meng [2], Quansheng Wang [2], Youqi Deng [2],
[1] Institute of Applied Electromagnetics, Sichuan University, Chengdu, China
[2] College of Physical Science and Technology, Sichuan University, Chengdu, China

Microwave heating is known for its efficiency and instantaneity. However, the non-uniformity of the microwave heating has limited the development of its application in industry. In order to solve this problem, a metal patch sticking to the turntable was proposed. During the heating ... 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

[3]University of Illinois at Urbana - Champaign, Urbana, IL, USA

A COMSOL Multiphysics® model of our apparatus has been created in order to simulate the pressurizations of our nanoparticles by Deuterium. Using reference measurements during a cooling process, we calibrated the model so that its thermal aspects reflect the ones of our experimental set ... Read More

Strong Localization and Rapid Time Scales of Superheating in Solid-State Nanopores new

E. Levine[1], G. Nagashima[1], D. Hoogerheide[1], M. Burns[2], J. Golovchenko[1]
[1]Harvard University, Cambridge, MA, USA
[2]Rowland Institute at Harvard University, Cambridge, MA, USA

Extreme localized superheating and homogeneous vapor bubble nucleation have recently been demonstrated in a single nanopore in thin, solid state membranes [1]. Aqueous electrolytic solution present within the pore is superheated to well above its boiling point by Joule heating from ionic ... Read More

An Approach to Modeling Vacuum Desorption new

C. F. Gomez[1], R. Schunk[1], R. F. Coker[1], J. Knox[1]
[1]NASA Marshall Space Flight Center, Huntsville, AL, USA

The objective of this simulation effort is to develop a mathematical model of vacuum desorption on a POC (Proof of Concept) canister loaded with Zeolite 13X/5A . This canister contains a pelletized adsorption bed which is used to adsorb H2O and CO2. Once this bed is fully saturated with ... Read More

Multiphysical Simulation of Moved Data Cable

M. Raum [1]
[1] Friedrich-Alexander Universität, Erlangen, BY, Germany

In general this thesis is about the effects of mechanical stress on data cables in moved applications. If a data cable is loaded with different kind of forces and used within high frequency applications it is possible, that the geometrical changes may have an impact on the electrical ... Read More

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 ... Read More
