Modelling and Simulation of Simultaneous Intrinsic Kinetics, Hydrogen Transport and Heat Transfer in Complex Hydride Hydrogen Storage Systems

G. A. Lozano, J. M. Bellosta von Colbe, T. Klassen, and M. Dornheim
Institute of Materials Research
Materials Technology
Helmholzt-Zentrum Geesthacht
Geesthacht, Germany

In proper designs of hydrogen storage systems based on metal hydrides three processes are modelled and simulated: hydrogen flow (through the metal hydride bed), solid-state chemical transformation, and heat transfer (due to the highly exothermic chemical transformation). In this work, ... Read More

Impulsive Thermomechanics of hypersonic surface phononic crystals

F. Banfi[1], D. Nardi[2], and M. Travagliati[3]
[1]Dipartimento Matematica e Fisica, Università Cattolica, Brescia, Italy
[2]JILA, University of Colorado at Boulder, Boulder, Colorado, United States
[3]Center for Nanotechnology Innovation @NEST, Istituto Italiano di Tecnologia, Pisa, Italy

Ultrafast optical generation of pseudosurface acoustic waves is investigated in hypersonic surface phononic crystals. The thermomechanics is modeled from first-principles to follow the initial impulsive heat-driven displacement in the time domain. Spectral decomposition of the ... Read More

The Effect of the Dispersion Term on Flux of a Fluid in Permeable Media

O. Toscanelli, and V. Colla
Scuola Superiore S. Anna
Pontedera, Italy

The flux of a fluid in permeable media can be modelled using a continuous. To link the real system with the continuous model is mandatory to realize a suitable average of the equations and of the variables. The dispersion term comes from this averaging but it is not only a mathematical ... Read More

Numerical Simulation for Dimensioning a Rock Heating Experiment

P. Ralek, and M. Hokr
Technical University of Liberec
Liberec, Czech Republic

The paper deals with simulation of rock heating experiment in underground, testing the rock properties for geothermal application. The modeled process is unsteady heat conduction in 3D. We made several parametric studies to find the possible temperature range with uncertainty in some ... Read More

Numerical Analysis of the Effect of the Electrode Distance During the Determination of the Flammability Limits of Gases

F. Ferrero, M. Beckmann-Kluge, and V. Schröder
BAM Federal Institute for Materials Research and Testing
Berlin, Germany

Simulations with COMSOL Multiphysics were performed, in order to analyze the gas flow patterns during the induced ignition of gases. Simplified calculations were performed. The ignition spark was assumed to have a temperature of 2000 K and a laminar flow was selected. 2D calculations ... Read More

Simulation Enquiries on Energy Transfer Efficiency in Stored Fluids

E. Zinterl, and G. Jakopic
JOANNEUM RESEARCH Forschungsgesellschaft mbH,
MATERIALS-Institute for Surface Technologies and Photonics
Weiz, Austria

Heating or cooling of stored fluids by thermal energy exchange with the enclosing walls may be enhanced by improving the efficiency of energy transfer; energy loss to the ambient is equalized for all simulations. Buoyancy driven internal natural convective flow is assumed to be the main ... Read More
