The method of intrinsic low dimensional manifolds (ILDM) is
applied to gas phase kinetic equations associated with combustion
of solid energetic materials. Solution to common models is hindered
by a necessity to track the evolution of dozens of species over
times scales which vary by a factor as much as 1011.
The ILDM method is able to systematically reduce the number
of species which must be tracked, reduce the stiffness of the
governing equations, and maintain fidelity to the full solution
at user-specified coarse time scales. This comes at the expense
of losing information at fine time scales and developing large
tables which describe the evolution of species on slow time
scales. The method is applied to a common model for the combustion
of the explosive HMX.
