Experimental Study of Gasoline Flame Propagation Characteristic

By using of high-speed camera on the experimental platform of gasoline flame propagation, gasoline (93(#)) flame shape and propagation characteristic have been studied under different propagation angles. Experimental results showed that, an orange main flame zone and a blue flashover flame zone were observed in gasoline flame propagation processes; as the angle between propagation direction and horizontal plane increased gradually, the fluctuation range of the main flame narrowed gradually in perpendicular to gasoline surface direction, the speed of the main flame forward propagation tended to be uniform and the average value of it increased gradually in parallel to gasoline surface direction.
