Combustion characteristics of alkane two-droplet array Part 2. Two droplet array of n-Docosane

Abstract

Combustion of two n-Docosane droplets in air at room temperature is studied experimentally. The droplets are disposed vertically one above another and burning history of upper droplet is registered. A new accurate method for measuring an equivalent diameter of burning droplet is developed. As a result, burning rate constants of Docosane and Octadecane droplets are measured more accurately. The dependence of upper droplet burning rate on interdroplet spacing is analyzed.
