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.
