T1 TALBOT IMAGES DEFLECTION TOMOGRAPHY OF TEMPERATURE DISTRIBUTION IN PREMIXED METHANE−AIR FLAME OF COMPLEX STRUCTURE JF Journal of Flow Visualization and Image Processing JO JFV YR 2016 FD 2017-02-21 VO 23 IS 1-2 SP 25 OP 40 K1 Talbot images K1 tomography K1 methane-air flame K1 refractive index K1 temperature AB The results of probe measurements of radiation deflection angles by the method of Talbot images were used for tomographic reconstruction of the refractive index and temperature distribution in a methane−air flame of complex structure. The projection data were registered in different viewing directions by rotating the reacting gas flow forming system around the vertical axis. The filtered back projection algorithm was used to reconstruct the refractive index distribution. The temperature calculations were based on the disregard of the change in the flame composition. The results show that the optical diagnostic by Talbot images can be used to measure the temperature field in asymmetric reacting gas flows.
