COMSOL Multiphysics® Based Identification of Thermal Properties of Mesoporous Silicon by Pulsed Photothermal Method

N. Semmar[1], I. El Abdouni[1], A. Melhem[1]
[1]GREMI-UMR7344, CNRS/University of Orléans, Orléans, France

The silicon is mainly known under its single-crystal shape and polycrystalline. Since a few decades, a new type of morphology is developed: the porous silicon (p-Si). Meso-porous silicon (Mp-Si) is one of promising materials for future microelectronic chips multi-functionalization ... Read More

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

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

Impact of Electrode Surface/Volume Ratio on Li-ion Battery Performance

S. Das[1], J. Li[2], R. Hui[1]
[1]University of Kansas, Lawrence, KS, USA
[2]Kansas State University, Manhattan, KS, USA

The adoption of micro- and nanostructured electrodes is a promising technique to improve the performance of Li-ion battery, which increases the electrode surface area and improves the efficiency of ion exchange between the electrode and electrolyte. This performance improvement is ... Read More

Thermal Modeling in a Historical Building - Improving Thermal Comfort Through the Siting of a Passive Mass of Phase Change Material

D. Groulx[1], F. Herbinger[1], L. Desgrosseilliers[1]
[1]Mechanical Engineering, Dalhousie University, Halifax, NS, Canada

A model of an office room was created in the COMSOL Multiphysics® software to simulate heat transfer and study the impact of siting a mass of phase change material (PCM) in a room to increase thermal comfort. This study determined that incorporating the selected PCM, butyl stearate, in ... Read More

Improving Heating Uniformity of Dried Fruit in RF Treatments for Pest Control: Model Development and Validation

B. Alfaifi[1], J. Tang[2], Y. Jiao[2], S. Wang[3], B. Rasco[2], S. Jiao[2], S. Sablani[2]
[1]King Saud University, Riyadh, Saudi Arabia
[2]Washington State University, Pullman, WA, USA
[3]Northwest A&F University, Yangling, Shaanxi, China

Non-uniform heating is one of the most important challenges during the development of radio frequency (RF) heat treatments for pest control. A computer simulation model using finite element–based COMSOL Multiphysics® software was developed to investigate the heating uniformity of raisins ... Read More

Full System Modeling and Validation of the Carbon Dioxide Removal Assembly

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

The Atmosphere Revitalization Recovery and Environmental Monitoring (ARREM) project was initiated in September of 2011 as part of the Advanced Exploration Systems (AES) program. Under the ARREM project, testing of sub-scale and full-scale systems has been combined with multiphysics ... Read More

Simulations of Heat and Mass Transport During Biomass Conversion Processes Using 3D Biomass Particle Models with Realistic Morphology and Resolved Microstructure

P. Ciesielski[1], M. Crowley[1], L. Thompson[1], B. Donohoe[1], D. Robichaud[2], A. Sanders[3], M. Nimlos[2], T. Foust[2]
[1]Biosciences Center, National Renewable Energy Laboratory, Golden, CO, USA
[2]National Bioenergy Center, National Renewable Energy Laboratory, Golden, CO, USA
[3]Quantum Electronics & Photonics Division, National Institute of Standards & Technology, Boulder, CO, USA

Predictive simulations of biomass conversion processes will improve their technical performance and reduce economic uncertainty surrounding industrialization of biofuels production. The majority of present conversion simulations treat the biomass feedstock with simplifying assumptions ... Read More

Design of an Automated Thermal Cycler for Long-term Phase Change Material Phase Transition Stability Studies

D. Groulx[1], A. C. Kheirabadi[1]
[1]Mechanical Engineering, Dalhousie University, Halifax, NS, Canada

This paper highlights the use of the COMSOL Multiphysics® software during the design process of a thermal cycling system for regulated PCM phase transitioning. The primary purpose of the simulations was to predict the system behavior in response to an ON/OFF temperature control system ... Read More

Delamination of Sub-Crustal Lithosphere

P. Vincent[1], E. Humphreys[2]
[1]College of Earth, Ocean, & Atmospheric Sciences, Oregon State University, Corvallis, OR, USA
[2]Department of Geological Sciences, University of Oregon, Eugene, OR, USA

Introduction: Lithospheric delamination beneath the western U.S. is believed to be the driving mechanism responsible for the evolution of magmatic and topographic features observed at the surface in the western U.S.. This process requires hot asthenosphere to be in contact with the ... Read More

Generating Simulated Data for Spot Heating/IR Camera Analysis of Coal Slag Surfaces

M. Silva[1], T. Ring[1]
[1]Department of Chemical Engineering, University of Utah, Salt Lake City, UT, USA

For combustion simulations, the wall temperature and heat transfer is an important piece of information. Coal combustion systems typically have walls that are initially a cast ceramic, but, with time, slag is deposited on the surface and coal and soot are incorporated into the slag. It ... Read More
