The atomization of a gelled boron slurry fuel using two commercially available
airblast atomizers was studied at atmospheric pressure in non-reacting flow. The
atomization of water was also characterized for comparison. Each atomizer was operated
at two different liquid mass flow rates and several air/ fuel ratios. Drop size distribution
was measured using a Malvern 2600 HSD Laser Diffraction Particle Sizer, Drop sizes
acceptable for use in ramjet combustors could be obtained for the gelled slurry fuel from
both atomizers. However, this required air/fuel ratios too high for practical applications.
It appears that secondary atomization methods or different types of atomizers will be
required to obtain high ramjet combustion efficiencies with these fuels if they are to be
used over typical ramjet operating envelopes.
