Title: Fortran computer-code package for the evaluation of gas-phase viscosities, conductivities, and diffusion coefficients. [CHEMKIN]

Technical Report ·
OSTI ID:6381554

A Fortran computer-code package is described that is used for the evaluation of viscosities, thermal conductivities, diffusion coefficients, and thermal diffusion ratios. The package is in two parts. The first computes polynomial fits to the temperature dependent parts of the properties. The coefficients of these fits are passed to a subroutine package via a linking file. Then, any subroutine from a library of subroutines may be called to return either pure species properties or gas mixture properties. The fitting procedure significantly increases the computational efficiency of the subroutine package, yet typically it degrades accuracy by less than one percent. This package uses the chemical kinetics package CHEMKIN, and transport property subroutines are designed to be used in conjunction with the CHEMKIN subroutine library.
