BLAKE - A Thermodynamics Code Based on TIGER: Users' Guide to the Revised Program

Abstract

BLAKE is a general thermodynamics code for use primarily with IBM-compatible desktop personal computers. This code, which was derived from the original version of SRI's TIGER program, is intended primarily for making calculations on the combustion products from conventional military and electrically-heated gun propellants under chamber conditions (temperatures between 1,500 K and 10,000 K, and pressures up to 700 MPa). An important feature of this code is that it embodies a correction for non-ideal gas effects appropriate to its primary application. This correction is derived from a truncated virial equation of state in which the second virial coefficient is computed using the spherically-symmetric Lennard-Jones 6-12 intermolecular potential. The third virial coefficient is derived from a hard-sphere model. Another useful feature of the code is that it contains enthalpy data for 60 commonly-used propellant ingredients and some compounded propellants. It also contains enthalpy data for all of the various nitrocelluloses containing from 11.10 to 14.00% nitrogen. This report is a complete guide to the revised code as of December 1997 including some illustrative examples of its use.
