Quasi-instantaneous Two-dimensional Temperature Measurements in a Spark Ignition Engine Using 2-line Atomic Fluorescence
Two-dimensional thermometry by the two-line atomic fluorescence method (TLAF) from atomic indium performed in an internal combustion engine is reported for the first time. The engine was a modified production engine running on iso-octane fuel. Small quantities of atomized indium were admitted to the engine chamber by injecting solutions containing InCl3 mixed with iso-octane. Temperatures could...
متن کاملTwo-line atomic fluorescence flame thermometry using diode lasers
This paper reports on the first application of diode laser based LIF for pointwise temperature measurements in flames. The technique is based on two-line atomic fluorescence (TLAF) thermometry of indium atoms seeded at trace levels into the flame. Two novel extended cavity diode laser systems (ECDLs) were developed, providing tunable single-mode radiation around 410 and 451 nm, respectively, to...
متن کاملTwo-line atomic fluorescence as a temperature probe for highly sooting flames.
We investigate the applicability of two-line atomic fluorescence (TLAF) from seeded indium atoms for temperature measurements in highly sooting flames. The results show that TLAF holds promise for two-dimensional temperature measurements in sooting and fuel-rich flames under conditions in which other thermometry techniques fail, a result that is attributed to the superior characteristics of the...
متن کاملTwo-Line Atomic Fluorescence for Thermometry in Reactive Flows
Advances in the field of laser-based combustion diagnostics over the past decades have allowed for detailed characterisation, modelling and increased understanding of the complex combustion process. However; many combustion phenomena are still unexplained and there is a continued need for development and application of diagnostic tools to further the understanding of the combustion process. One...
متن کاملSpatially resolved temperature measurements in a flame using laser-excited two-line atomic fluorescence and diode-array detection.
Spatially resolved temperature measurements in a CH(4)-air flame have been achieved using two-line laser-induced fluorescence from indium atoms seeded to the flame.
