Blistering of Industrial Floor on Concrete Substrate: the Role of the Air Overpressure
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 ... En savoir plus
Modeling of a Helical Coil Heat Exchanger for Sodium Alanate Based on-board Hydrogen Storage System
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 ... En savoir plus

Improvements in the Modeling of the Self-ignition of Tetrafluoroethylene
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 ... En savoir plus
Cluster Diameter Determination of Gas-solid Dispersed Particles in a Fluidized Bed Reactor
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 ... En savoir plus
Approaches for Fuel Cell Stack Modeling and Simulation with COMSOL Multiphysics

Thermal Characterization of a Chemical Reactor Coupling COMSOL and ModeFrontier
For Hydrogen production purpose from bio-ethanol, IFP set up a pilot reactor that can work at high temperature (1000°C) and high pressure (20 bar). Experiments show that this reactor has a specific thermal behavior that should be modeled in addition to chemical and hydrodynamics to ... En savoir plus
Simulation of the Mechanical Stability of Inkjet-Printed Hierarchical Microsieves
Porous membranes with pore sizes in the micrometer scale are required in many micro systems dedicated to biological and chemical applications. If their thickness is in the same dimension like the pore diameter they are called microsieves. On the one hand, a thin membrane guarantees a ... En savoir plus
