THE DETERMINATION OF FLAME SPEED OF PENTABORANE-OXYGEN-NITROGEN MIXTURES,
Abstract
Pentaborane was selected as a representative boron hydride in order to obtain flame speed measurements over a wide range of fuel-air mixtures. Freely-propagating laminar flame kernels produced by spark ignition were photographed by the flash schlieren technique, and the flame speed was derived from the measured rate of growth of these kernels. The pentaborane-air flame velocity peaks slightly on the rich side of stoichiometric. The influence of oxygen concentration on flame speed is reported. Pentaborane flames show pronounced cellular structure of the flame front at all mixture ratios. (Author)
