Improvements in the Modeling of the Self-ignition of Tetrafluoroethylene

M. Beckmann-Kluge, F. Ferrero, V. Schröder, A. Acikalin, and J. Steinbach
Federal Institute for Materials Research and Testing, Technical University, Berlin, Germany

Tetrafluoroethylene (TFE) is a gas widely employed in industry, which can under specific circumstances experience an exothermic dimerization to octafluorocyclobutane. If the heat generated by this reaction cannot be dissipated to the surroundings, the temperature inside the reactor will ... Mehr lesen

Numerical and Experimental Study of a Concentrated Indentation Force on Polymer Matrix Composites

A quasi static indentation test on a laminate composite has been investigated numerically and experimentally. In particular, the test has been implemented by COMSOL Multiphysics® and optimizing the Finite Element and mesh. In addition, the numerical strain results have been validated by ... Mehr lesen

Multiphysics Modeling of Cellular Arrays Using Periodic Minimal Surfaces – A Drug and Gene Delivery Application

J.I. Rey, A.J. Llewellyn, R.J. Connolly, J.P. Jimenez, A.M. Hoff, and R.A. Gilbert
University of South Florida, Tampa, FL, USA

Minimal surfaces are found in nature from crystalline structures to biological nano and micro structures such as biomembranes, and osseous formations in sea urchin. An application to electrically mediated drug and gene delivery is presented. Periodic level surfaces which approximate ... Mehr lesen

A Multiphase Model to Analyze Transport Phenomena In Convective Drying

S. Curcio, and M. Aversa
Department of Engineering Modelling, University of Calabria, Rende, Italy

In the modern food industry one of the most important problems to face is to preserve products from deterioration: a widely used solution is the convective foods drying. Drying is based on a simultaneous transfer of both heat and water that takes place when dry and warm air flows around ... Mehr lesen

Multiphysics Simulations in Complex 3D Geometry of the High Flux Isotope Reactor Fuel Elements using COMSOL

J. Freels, and P. Jain
Oak Ridge National Laboratory
Oak Ridge, TN

A current research and development project is ongoing to convert the operating High Flux Isotope Reactor (HFIR) of Oak Ridge National Laboratory (ORNL) from highly-enriched uranium (HEU U3-O8) fuel to low-enriched uranium (LEU U-Mo) fuel. Because LEU HFIR-specific testing and experiments ... Mehr lesen

Magnetic Nanoparticles for Novel Granular Spintronic Devices
