CFD simulation of hydrogen mitigation by a passive autocatalytic recombiner

The simulations show that the predictions of the main variables (hydrogen recombination rates, hydrogen concentration, temperature, pressure) agree well with the experimental data. This demonstrates the suitability of CFD treatments of PAR behavior in a single compartment. Future validations should address the presence of steam in the initial mixture as well as multi-compartment geometries in order to increase confidence in CFD methods before upscaling to full containment scales.
