Ion Dynamics Related to Hypersonics
Abstract
This research focused on the study of reactivity and dynamics of ion systems with relevance to atmospheric chemistry and combustion processes. The mobility of the fuel ion, t-C4H9(+), was measured drifting in polar and nonpolar atmospheric gases. These measurements were compared to polarization theory and locked dipole estimates as well as to related ion mobility measurements to better understand differences in interaction potentials. unimolecular and bimolecular reactions of the t-C4H9(+) ion, among other hydrocarbon ions, were also studied to elucidate the stability and reactivity in combustion. The study was also extended to gas phase chemistry of deprotonated nitroalkane anions (R2C=NO2(-)), key intermediates in ion enhanced combustion/detonation of nitroalkanes. A technique to detect and quantify the neutral radical products of ion reactions was developed and improved. The results are especially relevant to fuel ion-molecule reactions and transport properties important in reducing ignition delay time and improving efficiency in hypersonics.
