Abstract
Polycyclic undane alkene dimers, C22H24 are members of a new class of high-energy-density hydrocarbon fuels. Their ignition characteristics have been evaluated as solid fuels under conditions of high shear flow. Samples of the dimer were cured with a styrene-polybutadiene copolymer (10% w/w) binder on the test chamber wall and convectively ignited by a gaseous flame in air at Mach 0.12-0.25, stagnation temperature and pressure of 300 K and 150-250 kPa, respectively. Ignition times and rates of heat release were measured. The results indicate that compared with hydroxy-terminated-polybutadiene fuel at the same thermodynamic conditions and geometrical configuration the dimer ignition times are one order of magnitude faster. The heat released by combustion by the dimers is more than twice as large. Phase change, ignition, and combustion processes of these fuels are investigated with the aid of scanning electron microscope, high-speed photography, and pressure and temperature measurements.
