MINIMUM IGNITION ENERGIES OF SIX PURE HYDROCARBON FUELS OF THE C2 AND C6 SERIES

摘要

Minimum spark-ignition energies at reduced pressures are reported for ethane, ethylene, acetylene, n-hexane, cyclohexane, and benzene　and the mean energy-pressure dependence is established to be E∞ l/p 1.76 for four of the fuels investigated. A relation between ignition energy E and maximum flame velocity U max is also presented.　This relation includes all the experimental data plus data from other investigatos and may be expressed approximately as U max ∞ l/E 0.8. Such interde¬pendence of the minimum ignition energy and maximum fundamental. flame velocity permits a reasonable estimation of either from the other with an accuracy sufficient to discern large differences in various pure fuels.
