The paper presents experimental studies of the liftoff and blowout stability parameters of pure hydrogen, hydrogen/propane and hydrogen/methane jet flames using a 2mm burner. Carbon dioxide and Argon gas were also used in the study for the comparison with hydrocarbon fuel. Comparisons of the stability of H 2 /C 3 H 8 , H 2 /CH 4 and H 2 /CO 2 flames showed that H 2 /C 3 H 8 produced the highest liftoff height and H 2 /CH 4 required highest liftoff, blowoff and blowout velocities. The non-dimensional analysis of liftoff height was used to correlate liftoff data of H 2 , H 2 /C 3 H 8 , H 2 /CO 2 , C 3 H 8 and H 2 /Ar jet flames tested in the 2mm burner. The suitability of extending the empirical correlations based on hydrocarbon flames to both hydrogen and hydrogen/hydrocarbon flames was examined.
