Abstract : The influence of tailpipe length on the stability of a flame anchored in a high-velocity propane-air stream contained in a 2-in. pipe test section has been experimentally examined. Two flameholders were studied; a bluff body and a reverse-jet. A satisfactory correlation of the bluff-body data was obtained by plotting (blowoff velocity) (tailpipe length)0.31 versus equivalence ratio. For the reverse-jet, the correlation procedure yielded a value of 0.64 for the exponent on tailpipe length but the correlation was poorer. A better correlation of the bluff-body data was obtained when the exponent on tailpipe length was taken as a function of equivalence ratio. (Author)
