Ignition delays and temperatures of cool flame were experimentally measured for a single n-decane droplet in a high-temperature air by a thermocouple. Droplet diameter was about 1mm. Ambient pressure was atmospheric pressure, and ambient temperature was varied between 580K and 790K. Gas-phase temperature near the droplet was measured by a K-type thermocouple with a diameter of 25μm, whose hot junction was positioned under or over the fuel droplet. The distance between the droplet center and the hot junction was varied between 2mm and 10mm. From the thermocouple outputs, ignition delays and temperatures of cool flame were evaluated. Ignition delay decreased with increasing ambient temperature as expected. Cool flame temperature increased with increasing ambient temperature, and it ranged from 700K to 800K.
