Simulating the Flow of Native Silk Feedstocks In Vivo

J. Sparkes [1],
[1] Natural Materials Group, Dept of Materials Science and Engineering, The University of Sheffield, Sheffield, UK

The ability to artificially produce silk fibers has great commercial, industrial and scientific implications. Much has been made of their remarkable mechanical properties but few have considered how they are imparted on the initially liquid silk feedstock.1 I am exploring how silk duct ... En savoir plus

Using a Level-Set Model to Estimate Dwell Time in a Vacuum Dewatering Process for Paper

K. Rezk[1]
[1]Department of Energy, Environmental and Building Technology, Karlstad University, Kronoparken, Sweden

Water removal during paper manufacturing is an intensive energy process. The dewatering process generally consists of four stages in which the first three stages, water is removed mechanically through vacuum pulses and pressing.The fourth stage involve thermal drying. The vacuum ... En savoir plus

Using COMSOL Multiphysics® Software and the Application Builder for Neutron Transport in Discrete Ordinates

C. J. Hurt [1], J. D. Freels [2],
[1] University of Tennessee, Knoxville, TN, USA
[2] Oak Ridge National Laboratory, Oak Ridge, TN, USA

Introduction: The numerical solution to the neutron transport equation is employed to study a variety of problems in nuclear engineering applications, including for both eigenvalue and fixed source studies. Historically, multiphysics analysis at the HFIR has utilized these solutions to ... En savoir plus

Multiphysics Analysis and Optimization of Mechatronic Device Applications for Switching Devices

O. Cracium[1]
[1]ABB, Ladenburg, Germany

Medium- and high-voltage circuit breakers and reclosers are important grid protection devices that connect different grid sources and increase the network/grid reliability. Currently, there is a clear need of increasing the numbers of switching operation. Therefore, the optimal design of ... En savoir plus

Integration of the DeProF Model for Two-Phase Flow in P.M. into the Subsurface Flow Module

M. S. Valavanides [1], E. D. Skouras [2], A. N. Kalarakis [3], V. N. Burganos [2],

[2] FORTH/ICE-HT, Patras, Greece
[3] TEI of Western Greece, Patras, Greece

Relative permeability maps for steady-state two-phase flow in porous media, delivered by implementing the DeProF model [1] algorithm, were integrated within COMSOL Multiphysics® software [2] to resolve field-scale flows in porous media. The mechanistic model DeProF [1], predicts the ... En savoir plus

Transient Analysis of the Buoyance Driven Flow in a Passive Solar System of Indoor Heating

G. Petrone, G. Cammarata, and L. Cammarata
Department of Industrial and Mechanical Engineering, University of Catania, Italy

This study aims to numerically investigate on a passive solar system for indoor heating called as \"Trombe wall\". The transient buoyancy driven flow characterizing that system and the thermal distribution are solved by numerically integrating the governing equations in COMSOL ... En savoir plus

Modeling of Porous Catalyst Pellets: Comparison of Diffusion Flux Models for Steam Methane Reforming

P. L. Mills [1], L. Olabanji [1], A. Nagaraj [1], A. Nanduri [1],
[1] Department of Chemical and Natural Gas Engineering, Texas A&M University - Kingsville, Kingsville, TX, USA

Introduction Steam reforming of natural gas has been the most common method for producing synthesis gas (CO + H2) for the production of H2, MeOH and NH3 for over half a century [1]. Production of H2 in the USA using steam methane reforming (SMR) is ca. 9 MM tons/yr. Global production ... En savoir plus

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 ... En savoir plus
