This work was performed as part of a project to study particle formation in flames. Knowledge of the species present at the flame front as well as the adiabatic flame temperature were considered essential in this undertaking. A program written by D.R. Cruise at the Naval Ordnance Test Station (NOTS) at China Lake, California, in 1964 to evaluate propellant systems was modified by G. Ulrich, P. Mudgett, and J. Toscano to perform the required calculations on an IBM 1130 computer. This modified version of the NOTS propellant evaluation program (PEP) was then converted for use on the DEC-System-10 at UNH. Since it may be necessary in future work to modify the algorithms used in the computation, a thorough knowledge of the internal structure of this program had to be gained along with expertise in the general area of equilibrium computation. This manual is a report of the effort and was written to make this knowledge readily available to other investigators on the fly ash project. The first part of the manual describes the problems encountered in large equilibrium computations and the theory behind the methods adopted in PEP. The second part is a detailed description of the program itself.
