In order to understand interactions of droplets, flamelets, and flows in the process of spray premixed burning, we have experimentally investigated the flow and flame characteristics and concentration field of a stagnation-point gasoline-spray premixed flame. As might be expected, similar to the diesel-spray flame, the gasoline-spray flame was found to be composed of a weak blue flame zone, indicating the burning of gaseous fuel, and a strong luminous zone, containing many distinct lines of bright yellow color showing the trajectories of burning gasoline drops. Distributions of drop size, drop axial velocity, and the gas-phase temperature for the flow field of the gasoline-spray flame were similar to the previous findings for the diesel-spray flame. Concentration measurements further show that, in the center core of the flow, the O-2 concentrations are nearly 20% in the upstream region and decrease slowly in the preheat zone of the blue flame; while passing through the thin blue flame, the O-2 concentrations decrease more pronouncedly in the droplet-burning zone and almost remain constant in the downstream region. It was also shown that the increase of the CO2 concentrations follow the decrease of the O-2 concentrations, and the CH4 variation is similar to the O-2 variation. For the spray flow examined in this study, the increase of CO concentration simply corresponded with the droplets burning after the blue flame.
