摘要
A simple one-dimensional model allowing fast predictions of: a gas composition and temperature profiles, a catalyst temperature profile and an overall hydrogen recombination degree has been developed for a passive catalytic recombiner. The model assumes that heat and mass transport processes, taking place in vertical channels between catalyst plates, occur in a highly non-isothermal, developing laminar gas flow and in conditions of mixed convection. A kinetic model of heterogeneous catalysis was implemented into the model and the heat radiation from the catalyst surface was accounted for. The model with no adjustable parameters was verified against experimental results available in literature and results of numerical simulations obtained by CFD methods.
