Analytic and Computational Studies on Micro-Propulsion and Micro-detonics
Abstract
The Principal Investigators were funded by the AFOSR to conduct several theoretical investigations on aspects of micro-propulsion and micro-detonics technology. These included: (i) An examination of unsteady inert and reactive flows in rectangular and cylindrical channels with side- and end-wall mass injection intended as a model of micro-size rocket thrusters. (ii) An investigation of two issues associated with developing small-scale pulsed detonation wave engines. These concern the dynamics and criticality of ignition in slender two-dimensional channels, and the derivation of better models that describe the failure of detonations to propagate in thin channels. (iii) Several theoretical studies on problems associated with micro-detonics (miniaturized explosive systems). Topics to be studied include detonation propagation, dffraction and extinction in micro-detonic systems, including investigations and fundamental modeling of bridgewire and explosive foil initiators.
