Condense-luminescence and global characterization of metal particle suspension combustion

• Thermally processed and untreated Al particles were reacted as suspended powder. Phase fractions of the 2 O 3 produced are linked with global radiant fluxes. Two different heat transfer rates for fast slow burning identified. The experimental methods used condense-luminescence. Condense-luminescence is energy from gas to condensed phase transition. Thermal processing aluminum (Al) such annealing followed by rapid quenching had been previously shown affect single metal particle rates. This study extends combustion a material-based exchange model. Experiments designed investigate resulting powder suspensions induce (fast slow) regimes. in closed bomb calorimeter. calorimeter monitored transient temperature changes release upon combustion. product residue was analyzed species concentration using X-ray diffraction. Results link oxide products fluxes system. Metastable alumina associated nano-oxide formation substantially higher thermally reactions also produces greater increased correspond emission which may result condensation formation. qualifies condense-luminescence means increasing particles. By strategically altering fuels control combustion, appreciable increases flux can transform
