Multiple tomographic datasets are averaged in order to reduce noise in the recorded attenuation field. Internal attenuation fields within the Bunsen cone give insight into thickening of the reaction zone as gas travels towards the top of the flame, and extraction of a thresholded isosurface via Otsu’s method allows for 3-D visualization of the flame front. Results presented here reflect encouragingly on the potential of XCT to provide powerful characterization of flame structure in three dimensions regardless of optical accessibility. 000014469 540__ $$aText je chráněný podle autorského zákona č. 121/2000 Sb. 000014469 653__ $$a 000014469 7112_ $$a24th International Congress of Theoretical and Applied Mechanics$$cMontreal (CA)$$d2016-08-21 / 2016-08-26$$gICTAM2016 000014469 720__ $$aDunnmon, Jared 000014469 8560_ $$ffischerc@itam.cas.cz 000014469 8564_ $$s131569$$uhttps://invenio.itam.cas.cz/record/14469/files/TS.FM03-2.05.pdf$$yOriginal version of the author's contribution as presented on CD, page 605, code TS.FM03-2.05 . 000014469 962__ $$r13812 000014469 980__ $$aPAPER
