Abstract
Chemical kinetic modelers make extensive use of shock tube ignition data in the development and validation of combustion reaction mechanisms. These data come from measurements using a range of diagnostics and a variety of shock tubes, fuels, and initial conditions. With the wide selection of data available, it is useful to realize that not all of the data are of the same type or quality, nor are all the data suitable for simple, direct comparison with the predictions of reaction mechanisms. We present here a discussion of some guidelines for the comparison of shock tube ignition time data with reaction mechanism modeling. Areas discussed include definitions of ignition time; ignition time correlations (with examples taken from recent nβheptane and isooctane measurements); shock tube constantβvolume behavior; shock tube diameter and boundary layer effects; carrier gas and impurity effects; and future needs and challenges in shock tube research.

## Abstract Highβtemperature detailed chemical kinetic reaction mechanisms are developed for all nine chemical isomers of heptane (C~7~H~16~), following techniques and models developed previously for other smaller alkane hydrocarbon species. These reaction mechanisms are tested by computing shock t
Detailed one-dimensional calculations have been pertbrmed to simulate reflected shock tube experiments in the weak and strong ignition regime in hydrogen-oxygen-argon mixtures. It is tbund that the experiments and simulations agree well in the strong ignition case studied, In the weak ignition case,
