Description
Summary:The paper addresses the analysis of diffusion combustion of composite preliminary vaporized fuel composed of n-decane with small amount of non-oxidized Al nanoparticles. For the experimental study, the special burner has been developed. The distribution of temperature both along the flame and in the transversal direction has been measured by using CARS diagnostic system. It has been shown that, upon burning of composite fuel with 2.5% Al nanoparticle content (per mass), the temperature both at the near flame axis and near flame front regions has been notably higher (by 300–400 K) than that upon burning of pure n-decane. The possible explanation of this effect has been proposed.
