Abstract

Low pressure (35 torr) strained acetylene/oxygen flames similar to those used for diamond chemical vapor deposition are studied using laser-induced fluorescence (LIF) and mass spectrometry. Relative OH concentration and OH rotational temperature profiles are obtained by LIF, while absolute mole fractions of C₂H₂, CH₄, H₂, and CO are measured at the substrate by mass spectrometry. The results of the diagnostics are compared with the predictions of a one-dimensional strained flame code. The agreement between model prediction and experiment is generally good and usually within experimental uncertainties.
