[3]Centre Scientifique et Technique du Bâtiment, France

Surface coating can fullfil their function satisfactorily over an extended period of time only if there is a good bond between the concrete substrate and the coating. The most numerous cases of blistering affect the airtight covers of the concrete subjected to negative pressures of ... Mehr lesen

Modeling of a Helical Coil Heat Exchanger for Sodium Alanate Based on-board Hydrogen Storage System

S. Kumar[1], and M. Raju[2]
[1]General Motors R&D Center, Warren, MI, USA
[2]Optimal CAE Inc., Detroit, MI, USA

Hydrogen refueling in a metal hydride based automotive hydrogen storage system is an exothermic reaction and hence an efficient heat exchanger is required to remove the heat for fast refueling. In this paper a helical coil heat exchanger embedded in a sodium alanate bed is modeled using ... Mehr lesen

University of Pannonia, Veszprem, Hungary

Nowadays mathematical models are applied in almost every field of our life to predict how real systems behave. Computational Fluid Dynamics (CFD) has become a standard tool for analyzing various situations where fluid flow has a significant effect on the studied processes. Complex models ... Mehr lesen

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

Cluster Diameter Determination of Gas-solid Dispersed Particles in a Fluidized Bed Reactor

M. Das
Department of Biotechnology, PESIT, Bangalore, Karnataka, India

Clustering is a common hydrodynamic characteristic observed among suspended gas-solid particles in a fast fluidized bed (FFB) regime of a circulating fluidized bed (CFB) system. In this paper clustering behavior has been studied with Geldart group B particles like coal and iron ore in a ... Mehr lesen
