Abstract
The report gives results of a study to develop a predictive understanding of individual droplet trajectories in turbulent diffusion flames. In the incineration of liquid hazardous wastes, atomization quality may limit destruction efficiency. Large, nonmean droplets in a fuel spray can pass through the flame zone prior to complete evaporation, and may subsequently fail to burn completely due to insufficient temperature and/or flame radicals. Data from 10 trajectories were correlated using asymptotic forms for drag coefficient. A trajectory model containing the local drag coefficient was fit to the experimental data by a nonlinear regression. The resulting model was then able to predict 4 additional measured trajectories and 39 additional measured trajectory endpoints with acceptable accuracy. Thus, the influence of droplet spacing on the local drag coefficient of a single droplet has been quantified. Predictions of model penetration are very close to experimental findings, except for changing initial spacing of droplets.
