Abstract:

An experimental investigation was conducted on the addition of viscosity reducing additives to RJ-5 fuel. The tests were to determine if the additives hindered or improved the combustion efficiency of the basic RJ-5 fuel. The tests were conducted in a 12 inch diameter dump combustor with a LD of 4, no flameholder and a 50 nozzle at three different inlet air temperatures. The fuels employed for the tests were JP-4, RJ-5, SI-80 20 isobutylbenze and 80 RJ-5 and HDF-2 21 exo-tetrahydrodicyclopentadiene and 79 RJ-5. At inlet air temperatures of 750 R pronounced differences in combustion efficiencies were observed for the four fuels. As the inlet air temperature was raised to 1250 R, these differences tended to become greatly diminished.
