Carbon-slurry secondary atomization. Interim report, August 1984-February 1986
Various agents that might be incorporated with the carbon and/or with the JP-10 phase of the slurry for their ability to cause micro-explosions in slurry droplets on heating (and to develop a method to observe and evaluate the behavior using laser radiation as the energy source for explosion initiation) were screened. Experimental investigations were conducted on effect of additives in inducing and intensifying microexplosion of combusting carbon-slurry droplets. A new droplet generator capable of producing small droplets of well-controlled size was developed for the slurry fuel used. Agglomerate fragments produced through microexplosion were collected by using an impactor-type sampling probe and statistically analyzed. Results show that the fragment sizes follow the log-normal distribution, and that addition of 5% volatile miscible fuels to the carbon slurry can significantly reduce the mean fragment size.
