This paper describes the modelling of a hydrogen production process by direct splitting of water in a dissociation reactor in which the high temperature reaction occurs, followed by quenching with gaseous jets to recover the hydrogen produced. Proposed models, dealing with the dissociation reactor and principally with the two designed quenching devices, take into account the various physicochemical phenomena (heat transfer, complex chemical reaction, gas mixing). The quenching rate (up to 10 6 K/s) and theoretical gas composition at the outlet of the overall reactor can be calculated in a fairly good agreement with experimental results.
