/RESUME This paper is devoted to experimental and numerical predicting of the recombination coefficient Oγ and chemical energy accommodation coefficient β in the surface-catalyzed oxygen atom-atom recombination based on experiments performed on the MESOX set-up. Experimental results on these two coefficients are presented for silica (cristobalite) in the temperature range 1000-1800 K, for 200 Pa total air pressure. First, a one-dimensional physical-mathematical model for MESOX set-up multi-component diffusion and heat transfer processes is presented for the determination of both the coefficients Oγ and β for silica surfaces. Then, a comparison of the calculated heat fluxes and profiles of the atomic oxygen recombination with the data obtained in the MESOX set-up is performed.
