BLAKE - A Thermodynamics Code Based on TIGER: Users' Guide and Manual
Abstract
BLAKE is a general thermodynamics code derived from the SRI TIGER code. It is intended primarily for making calculations on propellant gases under gas chamber conditions (temperatures between 1500 K and 4000 K and pressures up to 700 MPa) on the combustion gases formed by military propellants. The unique feature of this code is that it embodies a correction for non-ideal gas effects appropriate to this application. It uses a truncated virial equation of state for this purpose. The second virial coefficient is computed using the assumption that the Lennard-Jones 6, 12 intermolecular potential applies. The third virial coefficient is computed for a hard-sphere model. Appropriate mixing rules are used for intermolecular force constants and for the virial coefficient. Another valuable feature of the code is that it contains enthalpy data for 49 of the ingredients most often found in military propellants and for the 300 nitrocelluloses with percentages of nitration between 11.00 and 14.00. This report is a complete guide to the local implementation and use of the code. It contains illustrative examples of its use, and its application to the AUTOCAP exercise, and a discussion of its experimental validation.
