CFD modelling of the off-gas system HIsarna iron making process part 2: reflux chamber geometry modification and effects on flow behaviour

A three-dimensional computational fluid dynamics (CFD) model for the HIsarna off-gas system is set up and validated by real plant data. In the model detailed reaction mechanism and kinetic data for post-combustion of CO-H2 mixture and carbon particles are incorporated. The results are presented and discussed in another study (Part 1) by the...

Modelling Internal Reforming Solid Oxide Fuel Cells with Surface Chemistry to Find Regions Susceptible to Carbon Deposition

The lifespan of internal reforming solid oxide fuel cells (SOFCs) is not yet sufficient. Among other design challenges, this is due to detrimental carbon deposition formations. This must be mitigated, without compromising the power output and efficiency of the fuel cell for it to become a commercial viable product. The carbon that is deposited...
