Fig. 5From: 3D flame reconstruction and error calculation from a schlieren projectionGradient of the density of hot gases obtained from the schlieren measurements corresponding to the experimental conditions 1OS, 2OS, 3OS and 4OS air intake at the burner, respectively. The gas reaction zone depends on the amount of premixed air fuel as is described by the conical structures located in the base and close to the center of the flameBack to article page
