Composition, temperature, and ionization in the micro hydrogen-air diffusion flame
Combustion and Flame, 1983Abstract Characteristic features of the ionization of hydrocarbons in the micro hydrogen-air diffusion flame are discussed in terms of the temperature of the flame. The constant diluent-fuel ratio for optimal ionization is shown to be related to the flame temperature. A modified rate coefficient is proposed for the ionization step, CH + O → CHO

Abstract In the present study, characteristics of diffusion H2-air flame in three Y-shaped cylindrical micro-combustors with a diameter of d = 1, 2 and 3 mm were investigated experimentally. The mixture was ignited near the exit of a 200-mm long horizontal channel.

In this study, a set of experiments were carried out in micro- and normal gravities to study the flame shape and oscillation of co-flow laminar diffusion ethylene and propane flames. The experimental results show that in microgravity, the flame length and width are larger than those under normal gravity, and the ratio of flame length to width is lower ...

Abstract The present study demonstrated the novel control on nanostructures and reactivity of soot by CO2 local micro-injection in ethylene inverse diffusion flames. Both global and local sampling methods were employed to capture soot particles at different flame positions. Transmission electron microscopy (TEM), high resolution transmission electron

The estimation of the temperature of a dilute micro hydrogen-air diffusion flame
Combustion and Flame, 1970A method is proposed for estimating the “temperature” of a micro hydrogen-air diffusion flame on the basis of the hydrogen content of the unburnt gas mixture. It assumes that the flame, being small, behaves as a prernixed flame, composed of hydrogen and oxygen in stoichiometric proportions diluted by nitrogen; the composition is expressed in terms of a
