The present study has been conducted to investigate the behavior of the flame base near the stability limits of a hydrogen jet diffusion flame. The color schlieren technique is employed to visualize the hydrogen flame, especially near the nozzle exit. The visible image makes clear two distinct types of stability behav-ior. One is the stabilized flame attaching to the burner exit, which occurs at or below the Mach number of unity. Another is the lifting flame which appears in the region of the Mach number of unity. The lift-off height and lift-off width at the flame base is calculated from the schlieren pictures and is related to the mass flow rate of hydrogen fuel.
