Anotace knihy

The reactions of two nano-thermites, aluminum (Al)§with copper oxide (CuO) and Al with nickel oxide§(NiO) are studied. These oxidizers were selected§based on their predicted properties: similar flame§temperatures but significantly opposing gas§generation. Thermal equilibrium calculations predict§that Al+CuO will have a high gas output and the§Al+NiO will produce little gas. Flame propagation§rates and peak pressure measurements were taken for§both composites at various equivalence ratios using§an instrumented flame tube. Results show that the§Al+CuO had approximately twice the propagation rate§and peak pressure of the Al+NiO. A DSC/TGA was used§to determine the properties of the composites and§reactants under low heating rates. Results indicate§that under slow heating both composites experience§almost no mass loss. The results suggest that the§melt-dispersion mechanism, which is only engaged at§high heating rates, leads to a dispersion of high§velocity molten Al clusters that promotes a pressure§build-up by inducing a bulk movement of fluid. This§mechanism may promote convection without the need for§additional gas generation.
