The Compressible Chemical Equilibrium and Transport code calculates thermodynamic and transport properties for a mixture in chemical equilibrium, including the dense gas correction.  This code also calculates the chemical potential, B values, for the thermo-chemical erosion analyses.

Improvements to the CCET 1.5^TM code include the addition of reflected detonation waves, oblique shock calculations, and a scram jet option.  Density Isp is now an output of the Rocket problem application.

With respect to erosion analyses, the CCET 1.5^TM code replaces both the BLAKE and ODE analysis in SEA gun erosion methodology. Recent modifications to the CCET 1.5^TM code include a reactants gun library, revised gas wall enthalpy calculation, and a selection criterion for calculating the chemical ablation potential.  The CCET 1.5^TM code is continuously being updated to reflect the changing needs of its users.  Most of the recent changes have been a direct result of the special requirements of the gun community.  Most of the enhancements identified last year (such as implementing all the NASA/LeRC CEA code applications and including the new high temperature thermodynamic data from the CEA code) have been completed.

The CCET 1.5^TM code is available on the following UNIX workstations:

• IBM RS 6000 (AIX 3.2)
• Silicon Graphics (IRIX 6.5)
• SUN SPARC (SunOS 5.7)
