Modelling of Reactive Non-Isothermal Mixture Flow and its Simulation in COMSOL Multiphysics® Software

V. Orava[1,2], O. Soucek[1], P. Cedula[2]
[1]Charles University in Prague, Prague, Czech Republic
[2]Zurich University of Applied Sciences, Winterthur, Switzerland

I introduce a model of fluidized reactor which, in presence of heterogeneous platinum-based catalyst, decomposes liquid formic acid producing gaseous mixture of carbon dioxide and hydrogen as the product. I treat the physical system as a (Class II) mixture of four constituents - namely ... En savoir plus

iCP 1.0: Stable Release Version of the Interface COMSOL-PHREEQC

A. Nardi[1], L. M. deVries[1], A. Sainz[1], J. Molinero[1]
[1]Amphos 21 Consulting, Barcelona, Spain

iCP (Nardi et al, 2014) is a software that couples two standalone simulation programs: COMSOL Multiphysics® and PHREEQC (Parkhurst & Appelo, 2013). The tool is ideal for applying multiphysics and geochemistry in Earth Sciences. Flexibility of the two coupled codes result in an ... En savoir plus

Heat Transfer Modeling of Steam Methane Reforming

E. Carcadea[1], M. Varlam[1], I. Stefanescu[1]
[1]National Research Institute for Isotopic & Cryogenic Technologies, Rm.Vâlcea, Romania

Steam methane reforming is a widely studied process because of its importance for hydrogen production. A two-dimensional membrane-reactor model was developed to investigate the steam-methane reforming reactions. The use of membrane as membrane-reactor separator offer us few advantages ...

Modeling of a Biogas Steam Reforming Reactor for Solid Oxide Fuel Cell Systems

F. Cipitì[1]
[1]CNR-ITAE, Institute of Advanced Technologies for Energy, Messina, Italy

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

Bio-Effluents Tracing in Ventilated Aircraft Cabins

G. Petrone[1], L. Cammarata[1], and G. Cammarata[1]
[1]Department of Industrial and Mechanical Engineering, University of Catania, Catania, Italy

Ventilation and Indoor Air Quality (IAQ) are issues of very high interest, determining comfortable conditions for occupants and no-contaminated local atmosphere. The aircraft cabins are more confined and have a higher occupant density than other indoor environments such as offices or ... En savoir plus

Numerical Simulation of Kinetic Interface Sensitive Tracer in Experiment with COMSOL Multiphysics® Software

F. Sun [1], A. Tatomir [1], F. Maier [2], M. Sauter [1]
[1] University of Goettingen, Goettingen, Lower Saxony, Germany
[2] Comsol Multiphysics GmbH, Goettingen, Lower Saxony, Germany

The kinetic interface-sensitive tracers (KIS tracers) are used to give a partial picture of the spreading, mixing and plume migration of supercritical carbon dioxide (scCO2) in the deep saline aquifer by estimating the interfacial areas between scCO2 and brine during the injection of ...

Model Development and Implementation of a Membrane Shift Reactor

J. Völler[1], M. Follmann[1], C. Bayer[1], and T. Melin[1]

[1]AVT Chemical Process Engineering, RWTH Aachen University, Aachen, Germany

Low temperature fuel cells require hydrogen of high purity for electricity production to avoid catalyst poisoning. To purify hydrogenrich flue gases from hydrocarbon steam reforming membrane shift reactors with a metal membranes may be utilized. A model of a tubular membrane shift ... En savoir plus

Calibration of a Bio-Kinetic Model to Simulate Microalgae Growth

A. Solimeno[1], J. Garcia[2]
[1]Department of Hydraulic, Maritime and Environmental Engineering, Universitat Politècnica de Catalunya, Barcelona, Spain
[2]Universitat Politecnica de Catalunya, Barcelona, Spain

The aim of present work is to present and calibrate a new mechanistic model that includes physical and biokinetic processes to reproduce the algae growth in photobioreactor or ponds during long-term scenarios. A COMSOL Multiphysics® model is used to implement the microalgae processes ... En savoir plus

Modelling of the Oxygen Consumption of Cells in the Cell Culturing Platform

A. Niazi[1]
[1]School of Mechanical Engineering, University of Birmingham, Birmingham, United Kingdom

A device for monitoring the oxygen consumption of cells has been developed, which consists of two parts; a cell culturing platform (CCP) and an oxygen sensing chip. The CCP possesses inlet and outlet pipes to direct the fluid under the test to the cell culturing chamber through the inlet ... En savoir plus

Solid Oxide Fuel Cell Material Structure Grading in the Direction Normal to the Electrode/Electrolyte Interface Using COMSOL Multiphysics®

M. Andersson[1], B. Sundén[1]
[1]Department of Energy Sciences, Lund University, Lund, Sweden

Fuel cells (FCs) are promising as an energy producing device, which at this stage of development will require extensive analysis and benefit from numerical modeling at different time- and length scales.
