Abstract
The direct statistical modeling method is used to study the influence of the coefficients of heterogeneous dissociation and recombination reactions on the flow of rarefied gas through a cylindrical channel. It is established that the degree of dissociation of the flow coming out of the channel is significantly dependent on the relationship between the dissociation and recombination coefficients. The technique for determining the dissociation and recombination coefficients on the basis of the experimental data is proposed.
