Effects of finite time response and soot deposition on thin filament pyrometry measrueemtns in time-varying diffusion flames

摘要

Prior work has shown that thin filament pyrometry (TFP) is a powerful approach for makign highly precise,spatially and temporally resolved line mearuements of temerpature in time-varying laminar diffusion flames.The technique has bene previously used to map out temperautre distributions as a funciton of phase angle for acoustically locaked flickering diffusion flames with two different levels of frocing.During these measruements two small erros in thetemerpature measrueemnts have been identified fro certain heights and phases.
