This paper explores the capabilities and limitations of thin filament pyrometry (TFP) when applied to the fiber(s) holding the fuel droplet. A 2D, two-color pyrometer is used to obtain the temperature along the fiber with low uncertainty and good spatial resolution. The derivation of the gas temperature profile from that of the fiber, however, entails a number of assumptions regarding the flow pattern around the droplet in the radiation/convection balance and also estimating the heat conduction along the fiber. Both aspects and the associated uncertainties are discussed in detail in a test with a 750 μm eicosane droplet hanging from two 15 µm SiC fibers and burnt in air; the “corrections” needed to estimate the maximum flame temperature sum up to ~ 300 K for a final value around 2000 K. The pyrometer is then applied to the soot cloud above the eicosane droplet, an alternative approach whose uncertainty arises mainly from that regarding the emissivity of soot. A reasonable agreement with the corrected TFP results is found. Finally, TFP is applied in a worst-case scenario, that is the case of a glycerol droplet, with no noticeable soot and a short distance between the flame and the droplet surface.Peer reviewedTaylor & FrancisJiménez, Santiago [0000-0001-9240-9644]Jiménez, Santiago [yago@litec.csic.es]Consejo Superior de Investigaciones Científicas [https://ror.org/02gfc7t72]202420242024info:eu-repo/semantics/articlehttp://purl.org/coar/resource_type/c_6501Publisher's versioninfo:eu-repo/semantics/publishedVersionapplication/pdfapplication/vnd.ms-excelhttp://hdl.handle.net/10261/357628reponame:DIGITAL.CSIC.
