Abstract: The results of an experimental study and numerical simulation of the relaxation of the composition of the flow of high-temperature combustion products in cylindrical channels with cooled and uncooled walls are presented. Primary attention is given to the effect of parameters such as the channel radius, the oxidizer excess coefficient in the initial mixture, and the wall temperature on the relaxation of carbon monoxide $\mathrm{CO}$ and on the level of its concentration at the channel outlet.
