Novel strategies for imaging temperature distribution using Toluene LIF

Abstract

The distinct temperature dependence of toluene fluorescence has enabled the application of toluene laser-induced fluorescence (LIF) for quantitative imaging of temperature. Two novel thermometry techniques based on toluene LIF are introduced and demonstrated: a single-color detection method, which can be applied for temperature measurements in homogeneously seeded flows and a two-color detection technique (i.e. the simultaneous detection of two different wavelength regions of the fluorescence spectrum) that can be applied in inhomogeneously seeded systems. © 2006 IOP Publishing Ltd.
