Profile data are presented here to aid research on the chemical structure of laminar, hydrocarbon diffusion flames - both for comparisons with other experimental results, as well as for evaluating the predictions of flame models. Specifically, measurements made at NIST during the period 1984-1998 of species concentrations (mole fraction), temperatures (K), and velocities (cm/s) are included for two diffusion flame systems. These files can be downloaded as desired. Note that some of the files contain more than 10 columns of data and thus are best viewed using a spreadsheet (such as EXCEL), rather than with a word processor.

Citation of these results should be as follows:
