“…All thresholds for ignition from the present hot surface are distinctly higher than AITs determined in extended hot vessels, which is consistent with previous data on hot surface size effects [4] . In addition, it is interesting to note the qualitatively different trends in AIT and hot surface ignition thresholds between the three fuels.…”

“…Seminal work on thermal ignition theory was done by Semenov (1940) who derived an analytical expression for ignition temperature as a function of surface area. Kuchta et al (1965) extended and simplified Semenov's findings. Gray (1970) investigated the effect of surface to volume ratio on ignition of NTC fuels, Law and Law (1979) solved the steady boundary layer equations for mixtures with high activation energies using matched asymptotics, and more recently Laurendeau (1982) proposed a simple model to estimate the minimum ignition temperature.…”

Hot surface ignition is relevant in the context of industrial safety. In the present work, two-dimensional simulations using simplified kinetics of the buoyancy-driven flow and ignition of a slightly lean n-hexaneair mixture by a rapidly heated surface (glowplug) are reported. Experimentally, ignition is most often observed to occur at the top of the glowplug; numerical results reproduce this trend and shed light on this behavior. The numerical predictions of the flow field and hot surface temperature at ignition are in quantitative agreement with experiments. The simulations suggest that flow separation plays a crucial role in creating zones where convective losses are minimized and heat diffusion is maximized, resulting in the critical conditions for ignition to take place.

“…For extended large surfaces, low-temperature chemistry needs to be considered. This latter configuration is more relevant to hydrocarbon fuels like n-alkanes which exhibit auto-ignition temperature on the order of 500 K as reported by Colwell and Reza [4], Kuchta et al [5] and Council [6]. For localized small surfaces, high-temperature chemistry needs to be considered.…”
