Beschreibungen/Notizen

• Ignition delays of cool flame (τ1) and of hot flame (τt) are experimentally measured for single n-decane, n-dodecane, n-tetradecane and n-hexadecane droplets, which have corresponding volatility to prevailing commercial hydrocarbon fuels, in hot air. Droplet diameter is 0.7 mm. Ambient pressure is 0.3 and 1.0 MPa. Ambient temperature is 550-1000 K. Results show the similarity of the examined fuels in terms of reactivity of the low- and high-temperature reactions. τ1 and τt are longer for the fuels with less volatility. τ2(=τt-τ1) is similar for the examined fuels. Ignition limits for cool flame and for hot flame are also similar, while they are slightly lower for the fuels with less volatility.
