ESTIMATION OF THE THERMODYNAMIC PROPERTIES OF SOLID PROPELLANTS

摘要

The paper presents a theoretical method, based on Corner's method, for the estimation of the thermodynamic properties of solid propellants. The mathematical model contains the truncated virial equation of state, the equilibrium constant equation for each chemical reaction, the mass and energy conservation equations. The virial coefficients were calculated from the intermolecular forces using the Lennard-Jones 6,12 potential function. Based on this model, a computer program, called REAL, has been written. At the end, one presents some results obtained with this program for three gun propellants.
