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

A Multi-Physics Framework for the Geometric Optimization of a Diaphragm Electrostatic Micropump

E. Bertarelli[1], R. Ardito[1], E. Bianchi[1], K. Laganà[1], A. Corigliano[1], G. Dubini[1], and R. Contro[1]

[1]Department of Structural Engineering, Politecnico di Milano, Milano, Italy

In this work, an electrostatic diaphragm micropump is investigated by means of COMSOL Multiphysics®. A fluid-dynamic model is adopted to evaluate the fluid flow characteristics inside the pumping chamber, in static conditions. In parallel, electromechanical quasi-static simulations ... Read More

Multiphysics Modelling of Food Dehydration during RF Exposure

R. Renshaw[1]
[1]e2v Ltd., Essex, United Kingdom

There is a requirement for an RF (Radiofrequency) industrial dryer that will be capable of dehydrating foodstuff to the correct level after the product has been fried. RF drying should actively target moisture, due to waters high dielectric properties. An industrial dryer can be ... Read More

Solving Two-scale Transport Laws During Frying of Foods Using COMSOL Multiphysics

J. Maneerote, and P.S. Takhar
International Center for Food Industry Excellence Texas Tech University, Lubbock, TX, USA

Microscale comprised of the scale of food biopolymers at which biochemical reactions and textural changes take place, and the macroscale was the scale of interaction of polymers with surrounding water, vapor and oil phases. Numerous novel equations such as generalized Darcy’s law based ... Read More

Modelling of Heat and Moisture Transport in a Corrugated Board Stack new

M. Xynou[1]
[1]KTH Royal Institute of Technology, Stockholm, Sweden

Corrugated board is produced on a machine where the corrugated medium is glued between two flat paper surfaces, the liners. The board is cut into sheets and stored in a stack until suitable moisture content has been reached. The sheets are then cut and creased into blanks for the ... Read More
