Abstract:

High-temperature rate constants have been computed for reactions undergone by major polyatomic combustion products in the nozzles of rocket engines. For about 55 of the reactions considered, the activation energies and rate constants were computed by a method based on a modification of the Johnston-Parr transition-state treatment. For the remaining 45 of the reactions considered, this method showed that the computed activation energies were insignificant above 1000 K. The rate constants and frequency factors of this 45 of the reactions were then calculated on the basis of an improved collision kinetics treatment. Computed high-temperature results are presented for more than 140 nozzle reactions including reactions of CH4, CH3, CH2, NH3, NH2, H2CO, HCO, HCN, HNO, H2O, HBO, AlOH, BeOH, and NaOH with combustion intermediates such as H, O, F, Cl, BO, BeO, AlO, OH, NaO, CN, NH, BH, CH, and NO.
