摘要

A mathematical model of heat and mass transfer in a passive autocatalytic recombiner (PAR) is developed. Three-dimensional calculations of convection of a hydrogen-containing medium in a hydrogen recombiner of the RVK-315 model series are performed using the ANSYS Fluent commercial code. Due to the periodic structure of the catalytic block, calculations were performed for one rod arranged in its middle. The results of calculations are correlated with the experimental data acquired using the OAO VTI stand. The mismatch between the calculated and experimental data does not exceed 30% in the range of bulk hydrogen concentrations of 1.5-6.5%.
