| Abstract: | The influence of CF3Br, CF2HBr, CF2HCl and CF3H on a benchmark mixture composed of stoichiometric H2−CO−O2−Ar is experimentally investigated. Several ratios hydrogen/carbon monoxide are studied. For each benchmark mixture, the initial
pressure is adjusted in such a way that the detonation cell sizes are quasi identical. The effect of the additives on the
detonation velocity and the detonation cellular structure is analyzed. The experiments show that CF3Br is the best inhibitor and CF2HBr might be substituted for CF3Br. CF3H does not inhibit the detonation wave. Simple chemical kinetics analysis gives us a better understanding of the inhibiting
and promoting effect of the halocarbons.
