Finite Rate Modeling of Otto II Monopropellant Combustion
Abstract
ABSTRACT:The U.S. Navy interest in restarting procurement of the torpedo Mk 48 offers a segway into a better understanding of the Otto II combustion process that is key to the operation of both the heavyweight Mk 48 as well as the lightweight Mk 46 and Mk 54 variants. A better basic theoretical understanding of Otto II combustion is necessary for improvement in efficiency (range) as well as startup reliability. This White Paper offers a kinetic approach to modeling the Otto II combustion process; an approach that has not been applied before. The Chemkin chemical kinetics modeling suite will be employed. Models will be developed for both vapor phase and droplet surface mechanisms for the decomposition/combustion of Otto II. This approach will be combined with a similar treatment of the initial startup solid grain combustion process. Finally, an Otto II droplet energy balance will be used to define the locus of conditions that support optimal operation and startup for different pressures and other operating conditions.
