A light-scattering method for soot concentration measurements

摘要: The validity of light-scatter measurements as a basis for determining soot particle size and concentration from point to within flame has been examined in relation on special propane burner. monodisperse spherical model relied the past was found predict scatter diagrams poorer agreement with experiment than cluster developed here. Both electron micrographs collected support chaincluster model, which predicts addition mass concentrations that are factor 2 those determined by total filtration. Soot were made turbulent acetylene diffusion demonstrate technique application system characterized large background radiation. be uniform throughout burnout region, rate first order deduced. These results consistent burning eddies soot-containing gas mix oxygen-rich particles burn rapidly.
