Abstract

Measurements were made of burning rates of hexadecane droplets 0.5 to 1 mm in diameter, suspended on quartz fibers in room-temperature air, at pressures from 1 to 0.1 atm. Correction factors for effects of natural convection and finite-rate gas-phase chemical kinetics are determined by least-square fitting of the burning-rate constant. Reexamination of a large amount of earlier data on burning rates of unbranched alkanes reveals appreciable influences of forced and/or natural convection. If corrections for these effects are calculated by evaluating properties at the arithmetic mean of the ambient and flame temperature, then theoretical and experimental burning rates agree within 15%.
