“…15 when the dissociation is weak, the concentration of fuel is also low there near stoichiometry. The competing effects result in a shift of the maximum burning rate away from that of the flame temperature, as has been observed by Jones et al (1931) and Simon and Wong (1951). To be sure, the calculation is sometimes extended to the burning rate itself (which involves the mechanics of the flame in addition to its thermodynamics) but again numerically, the second unsatisfactory aspect.…”

s-The burning rate of a fuel-oxidant mixture is invariably found by experiment to have a maximum slightly on the fuel-rich side of stoichiometry. The usual explanation is that the maximum adiabatic flame temperature is shifted there by dissociation of the products. However, several aspects of this explanation are unsatisfactory: the burning rate depends on other factors than the flame temperature, especially near stoichiometry; verification is always numerical and hence for a limited range of parameters; and cool flames, where dissociation is negligible, are excluded. The present paper is an analysis of a two-reactant model, with not necessarily equal Lewis numbers K and L for oxidant and fuel (respectively), in the absence of dissociation. In particular, it is found that the phenomenon occurs whenever K is large enough and L small enough, the precise conditions nearly always being met in practice. In other words, diffusion alone provides a satisfactory explanation. Part 11 will incorporate dissociation to show that, while it does explain the shift in maximum temperature, it has a subsidiary effect on the maximum burning rate.

“…During the process, the stability of the ame is monitored through an observation window made from a piece of a colorless transparent CD/DVD plastic case xed with tape on the lower side of the door. The obtained bluish ame is particularly adapted for the atomization of alkali metals 28 and features a lower background contribution compared to yellow ames.…”
