Modeling the Thermo-Mechanical Structure of Energetic Material Flames

176 p.Thesis (Ph.D.)--University of Illinois at Urbana-Champaign, 2005.The problem of efficiently computing the stable burn-back of a solid rocket motor when the motor is in the quasi-steady burning regime of operation is considered. Through the use of a straightforward two-timing multi-scale asymptotic analysis, the reduced description of the quasi-steady burning regime for a model problem is developed that is extensible to a full three-dimensional rocket. Advanced time-integration strategies developed for the airspace industry are adopted to the solid rocket motor grain burning to compute a series of realizations of steady flows as the grain burns back to near completion.U of I OnlyRestricted to the U of I community idenfinitely during batch ingest of legacy ETD
