An Accurate Model for Sample Droplet Acceleration in Analytical Flames.
Abstract
The experimentally observed velocity of an aerosol droplet in an air-acetylene flame is compared to the velocity calculated through a new mathematical model. The experimental droplet velocity is measured by means of stroboscopic photography of a stream of individual droplets sent into a flame at a known frequency and traveling very reproducible trajectories. Because the temporal spacing between these droplets is known, a measure of the instantaneous droplet location enables their velocity to be calculated. The droplet acceleration model was modified by incorporating into it a spatially changing flame rise velocity, which was assumed constant in earlier treatments. Excellent agreement has been found between calculated and measured droplet acceleration in the flame. (Author)
