COMMENTS:

The Jacobs et al (1989) expression served as an optimization variable in GRI-Mech 2.1 release and was not changed. The TST expression of Wagner and Bair (1986) was adopted for version 3.0, since it fits this data and the high temperature results and others referred to in Wooldridge et al (1996).
Served as an optimization variable for GRI-Mech 3.0 and was not changed.
