The effects of initial pressure and temperature on the laminar burning speed of n-hexane-air mixtures were investigated experimentally and numerically. The spherically expanding flame technique with a nonlinear extrapolation procedure was employed to measure the laminar burning speed at atmospheric and sub-atmospheric pressures and at nominal temperatures ranging from 296 to 422 K. The results indicated that the laminar burning speed increases as pressure decreases and as temperature increases. The predictions of three reaction models taken from the literature were compared with the experimental results from the present study and previous data for n-hexane-air mixtures. Based on a quantitative analysis of the model performances, it was found that the most appropriate model to use for predicting laminar flame properties of n-hexane-air mixtures is JetSurF.
