Abstract : A 1-7/8 inch inside-diameter combustor has been developed which can be used to m8eUure and compare the blow-out velocities of single-component fuels, slurries, and fuel mixtures having a wide range of reactivity and physical properties. The blow-out velocities of isooctane, n-heptane, isopentane, allyl chloride, and propylene oxide varied in the same way as the flame speeds of these fuels determined by the Bunsen flame method. The blow-out velocity of 50.percent 1.5-micron magnesium slurry was much higher than that of the 50-percent 15-micron magnesium slurry. The blow-out velocity of JP-4 was not increued by the addition of 50-percent boron. Rowever, the addition of 5-percent pentaborane in JP-4 substantially increased its blow-out velocity, and 40-percent pentaborane in JP-4 had a blow-out velocity that approached that of 50-percent 1.5-micron magnesium slurry.
