Modeling of a Biogas Steam Reforming Reactor for Solid Oxide Fuel Cell Systems
A biogas steam reforming reactor has been developed in order to be integrated into a proof-of-concept SOFC system, able to operate with biogas produced in an industrial waste water treatment unit. A mathematical model, aimed at describing the performance of the reactor, has been ... En savoir plus
Numerical Modeling and Performance Optimization Study of a Dehumidification Process in Nuclear Waste Storage
One of the main parameters to consider during the nuclear waste storage design phase is the drum corrosion risk. The humid-air corrosion models available in literature predict that, for carbon steel, the phenomena start to become appreciable for relative humidity (RH) values close to ... En savoir plus
Simulation of Reactive Transport in Porous Media: A Benchmark for a COMSOL-PHREEQC-Interface
The reactive transport simulation interface COMSOL-PHREEQC, developed by Wissmeier & Barry (2011), provides a MATLAB®-based coupling interface to combine COMSOL Multiphysics® for flow and heat transport simulations and PHREEQC as a geochemical batch reaction simulator. The ... En savoir plus
Water Quality Modeling of Drinking Water Storage Reservoir Noardburgum
The water storage reservoir at the WTP Noardburgum is used to even out demand and supply and ensure a stable drinking water production capacity. At the moment the rectangular reservoir has a single pipeline which serves as an inlet during the fill cycle and as an outlet during the draw ... En savoir plus
Simulation of Gravitational Instability During CO2 Absorption in a NaHCO3/Na2CO3 Solution
This work deals with the modeling and the numerical simulation of the CO2 absorption, coupled with a chemical reaction, in an initially quiescent aqueous solution of sodium carbonate (Na2CO3) and bicarbonate (NaHCO3), inside a Hele-Shaw cell. In our Hele-Shaw cell, the liquid fills ... En savoir plus
