Instructions and Changes to the NEWPEP Thermochemical Code
The NEWPEP thermochemical code is a computer program that has been developed to help predict the performance of a user generated propellant system. Sandia has used the program to model the use of different oxidizer/fuel combinations. The program has been adapted to fit Sandia's need by expanding the programs combustion species database and the ingredient list. This paper provides the user with a thorough set of operating instructions.
