Spectrometric Study of Shock-Heated Mg/MgO Particle Dispersions
TLDR
In this paper, a premixed metal vapor-oxygen system for studying these kinetics was approximated by the combination of a shock tube with an exploding Mg wire particle generator.Abstract:
Homogeneous kinetics may play a large role in dictating diffusion flame structure for metals like Mg. A premixed metal vapor-oxygen system for studying these kinetics was approximated by the combination of a shock tube with an exploding Mg wire particle generator. This portion of the study was unsuccessful because the experimental data indicate the dispersion to consist of MgO rather than Mg particles. A kinetic mechanism is postulated which is consistent with the spectrometric observations. Certain wave interactions in the shock tube which severely curtail experimental times behind the reflected shock are also discussed.read more

Combustion of Magnesium with Carbon Dioxide and Carbon Monoxide at Low Gravity
TL;DR: In this paper, the burning behavior and ame structure of magnesium in pure carbon dioxide and pure carbon monoxide atmospheres in low-gravity conditions were investigated, showing that the burning time is proportional to the square of the metal sample diameter.

Experimental and numerical investigations on the decomposition and combustion characteristics of composite propellant with Mg/Al particles additives
TL;DR: In this article, a detailed combustion kinetic model was employed in the in-house computational solver to simulate this typical two-phase flow problem, and the combustion phenomenon was analyzed carefully about flame structure, chemical reaction order, and an obvious double-platform phenomenon was observed in the temperature distributions of combustion wave on central axis.

TL;DR: In this article, a numerical model for homogeneous nucleation and growth of MgO particles in a thermal plasma reactor is presented, and the results indicate that the number of particles nucleated is a function of initial Mg concentration and cooling rate in the nucleation region.

High-temperature fast-flow reactor studies ofmetal-atom oxidation kinetics
TL;DR: The tubular fast-flow reactor has been adapted to reach temperatures up to 2000°K, and has been applied to studies of gas-phase reactions of metal atoms with O 2, with the most extensive results obtained so far is for the Fe/O 2 reaction in a N 2 bath at 1600°K as discussed by the authors.
