Pyrolysis effects during high-temperature vaporization of alkane droplets

The temporal evolution of the droplet radius is measured experimentally in high-temperature inert atmospheres for three different alcohols (ethanol, n-butanol, and glycerol) and three alkanes (n-heptane, n-dodecane, and n-hexadecane). It is shown that, while accompanying theoretical predictions of droplet-radius variations show excellent accuracy for the three alcohols, the three alkanes exhibit vaporization rates that are significantly smaller...
