Composition Structure of Burning Sprays of Jet a Fuel and its Emulsions With Water Free

This paper presents the axial and radial concentration profiles of various species (O₂, N₂, CO₂, H₂O, NO, NO_x, and C_n H_m) in the burning sprays of Jet A fuel, its blend with 1 percent surfactant, and its emulsions with 1 percent surfactant and different water contents (5, 10, and 20 percent by volume). The composition structure of the flame studied is in conformity with the temperature, particulate concentration, and radiation profiles studied earlier. The results show that the increase of water content of emulsions decreases fuel pyrolysis and oxides of nitrogen, whereas the surfactant alone does not markedly affect the flame structure.
