Abstract

In this study an experimental, well-controlled parametric investigation of the behavior of an oscillating Burke-Schumann type spray diffusion flame is described. It is demonstrated that these unique spray-related oscillations occur at frequencies in the range 1-5 Hz and it is established that their genesis is due to a heat and mass transfer mechanism resulting from the presence of the droplets in the system. A complementary stability analysis of a one-dimensional model problem, containing the essential features of the experimental conditions, is performed. It is found that the correct order of magnitude of oscillations is predicted by the analysis, confirming a posteriori that the model is a satisfactory paradigm for examining the observed phenomenon.
