Exploratory Development of Illuminating Flares
Abstract
A mathematical flow model has been developed for plane two- dimensional illuminating flares dropping through the atmosphere and simulating face down burning. Numerical results are given infield plots showing streamlines, velocity potential lines, constant velocity lines, and constant time lines for two-dimensional, incompressible flow. Thermochemical calculations based on shifting equilibrium were made for combustion in the flare plume over a range of various mixture ratios. The results are provided in the form of curves and tables showing reaction products, equilibrium temperature, and other thermodynamic data. Temperatures in plumes of one inch diameter flares were measured by thermocouple. A theoretical evaluation of optical density in the plume and experiments to evaluate optical density were performed. The results are provided in tables, photographs of plumes, and traces obtained by spectrograph. Relative luminous intensity distribution in the plumes of downward burning flares was determined and the results are shown in terms of relative intensity contours, plots of relative intensity versus plume area, and plots of percent total intensity versus percent of plume area. An analysis of overall results was made utilizing information from the literature as well as that obtained in the program.
