Abstract: A method for estimating absolute concentrations of С$_2$H$_5$ and H radicals in hydrocarbon diffusion flames is proposed and substantiated. Concentration profiles of С$_2$H$_5$ and H on the flame axis are obtained. In the method proposed, the concentration of С$_2$H$_5$ is determined from the equality of two quantities – the rate of loss of n-butane by diffusion and the rate of its formation by recombination of two С$_2$H$_5$ radicals. The concentration of H radicals is determined from the relation between the ratio С$_2$H$_5$/H and experimental profiles of С$_2$H$_4$, С$_2$H$_6$, and O$_2$.
Keywords: absolute concentration of radicals, С$_2$H$_5$, H, laminar diffusion flame, propane, diffusion.
