Simulation of iron rods combustion in oxygen with the drop detachment

Abstract

The present article is a part of the research program to study the combustion of steel in oxygen at high pressure. A fundamental understanding of iron and steel combustion in oxygen is important to the selection and specification of safe materials for oxygen production, storage and transport technologies. In the article a standard upward-burning ignition model was considered for cylindrical iron rods in oxygen with non-flowing test conditions. A combustion model with the drops separation to investigate influence of different burning factors on the combustion process was presented. The model results were compared with the NASA experiments to clarify the values that were introduced parametrically. The present model allows to calculate and visualize such combustion parameters as burning velocities, the period of droplet detachment, temperatures and stoichiometric compositions of melt droplets, etc. The Wolfram Mathematica 9.0 program was used for simulation.
