Abstract

The equation of state for gas phase polytetrafluoroethylene (PTFE) is calculated with a two-temperature LTE formulation. Twenty-five chemical species are included in the analysis. Sample calculations are performed for pressures from 0.001 atm to 1.0 aim and for temperature ranges of 0.1 ev to 4 ev for both heavy particle and electron temperatures. The preliminary results using the Mach2 MHD simulation program show large discrepancies between the calculated equation of state and that in the LANL SESAME tables used by Mach2. The results clearly show the importance of including complex molecular plasma effects in the simulation of the pulses plasma thrusters and related devices.
