Combustion of artificial graphite in stagnation flow: Estimation of global kinetic parameters from experimental results
- Shizuoka Univ., Hamamatsu (Japan). Dept. of Energy and Mechanical Engineering
The combustion of graphite rod in the stagnation flow of an oxidizer is studied experimentally in order to investigate the coupled nature caused by the interaction between the gas-phase and surface reactions. Not only the combustion rate of the graphite rod but also the surface temperature at which the CO flame is established in the forward stagnation region of the burning graphite is measured. By investigating effects of ambient pressure, oxidizer, and concentrations of oxygen and water vapor as well as graphite density, it is experimentally observed that the establishment of the CO flames yields the reduction of the combustion rate. By estimating kinetic parameters for the surface and gas-phase reactions with the combustion rate and the surface temperature at the ignition of CO flame, respectively, and by comparing the predicted results with experimental data, it has turned out that the appearance of the CO flame can be predicted when kinetic parameters for the surface and gas-phase reactions are known.
