A finite difference model for the combustion of zirconium in oxygen

The combustion of zirconium in oxygen was simulated using a two-dimensional finite difference model. The model accounts for heat generation by the oxi dation reaction and heat loss due to convective and radiative processes. Us ing geometric considerations along with the heat transfer conditions, the m odel was utilized to determine the effect of dilution and particle size on the combustion process. Dilution was examined in regular and random geometr ies and the results showed a marked influence on the nonlinearity of the wa ve. The effect of particle size was also examined as a function of the geom etry of diluent dispersion.
