The combustion instability of premixed bluff-body flame under acoustic excitation at different equivalence rates(0.8,1.0,1.2)and hydrogen volume fraction(0,10%,20%)was analyzed.The combustion instability could be captured by the flame transfer functions and the flame front distribution could be shown by CH chemiluminescence measurement.Results showed that the combustion characteristics were very sensitive to the fraction of hydrogen in the fuel mixture.When equivalence rates were 0.8 and 1.0,the amplitude o...
