Abstract:

An investigation of the mixing and radiation properties of buoyant turbulent diffusion flames is described. The study was divided into two phases: (1) the structure and mixing properties of buoyant turbulent plumes, which must be understood in order to resolve effects of turbulence/radiation interactions and to benchmark models of buoyant turbulent flows; and (2) the fractal and structure properties of soot aggregates, which must be understood in order to develop nonintrusive methods for measuring soot properties and to estimate the continuous radiation and heterogeneous reaction properties of soot in flame environments.
