Comprehensive study of initial diameter effects and other observations on convection-free droplet combustion in the standard atmosphere for n-heptane, n-octane, and n-decane

This paper reports the results of a comprehensive experimental study on the effect of initial droplet diameter (Do) over a very wide range (0.5 mm < Do < 5 mm) on the spherically symmetric droplet burning characteristics in the standard atmosphere of three alkanes – n-heptane, n-octane and n-decane – that are representative of components found in petroleum-based transportation fuels and their surrogates. Spherical symmetry in the burning process...
