Heat and mass transfer modelling in a three-phase AC hydrogen plasma torch: Influence of radiation and very high pressure

International audienceA 3 dimensional CFD simulation of a hydrogen plasma process is performed for two different operating pressures. Special attention is given to radiative heat transfer by computing a highly detailed spectral data base for hydrogen. Results show the importance of radiative heat transfer in the concerned plasma technology. A key role of the ceramic protection in this process has also been confirmed
