CFD Modelling of Gas-Solid Reactions: Analysis of Iron and Manganese Oxides Reduction with Hydrogen

Metallurgical processes are characterized by a complex interplay of heat and mass transfer, momentum reaction kinetics, these interactions play crucial role in reactor performance. Integrating chemistry transport results stiff non-linear equations longer time length scales, which ultimately leads to high computational expense. The current study employs the OpenFOAM solver based on fictitious domain method analyze gas-solid reactions porous medium using hydrogen as reducing agent. reduction oxides with involves hierarchical phenomena that influence rates at various temporal spatial scales; thus, multi-scale models needed bridge scale from micro-scale macro-scale accurately. As first step towards developing such capabilities, analyses reacting flow methods cases related iron manganese oxides. Since interest requires significant modifications industrial processes, this model can aid design optimization. was verified against experimental data dynamic features observed progresses is well captured model.
