Student Research in Metallic Fuel Combustion Kinetics. FY 91 ASSERT.
Abstract
The use of new advanced solid rocket propellant constituents, such as, e.g., boron as HEDM and ammonium nitrate as replacement for halogen-containing oxidants, requires knowledge of their combustion characteristics. To this end experimental rate coefficient k measurements on individual important Al and B species reactions were made in the 300-1800 K temperature range using a high- temperature fast-flow reactor. Temperature dependent rate coefficient expressions k(T) = AT(super n)exp(-E/RT) are found for the reactions between AlO and CH4, O2; Al and N2O; AlCl and N2O, CO2, SO2; BCl and N2O, SO2; BO and CO2. To allow semi-empirical predictions for further metal oxidation reactions, two semi-empirical theories have been developed and utilized. These are Semi-Empirical Configuration Interaction theory for prediction of E from one species to another and Metals-Transition State Theory for prediction of k(T) from k at one temperature. Dual military-civilian applications of this work are discussed. jg p2
