Abstract
The problem of non-disturbing diagnostics of the phase and temperature fields of the reacting jets and flames is solved in the work. On the example of an axisymmetric hydrogen-diffusion flame, a method was developed, based on Hilbert polychromatic visualization of phase optical density fields, and measuring the temperature profile in selected areas of the medium under study. The diagnostic complex is implemented on the basis of the IAB-451 device. The visualized diffusion flame in the axial symmetry approximation is analyzed using the Abel transform. The reconstruction of the temperature field is carried out considering the diversity of the partial optical properties of the gas mixture in a model consistent with the Gladstone-Dale dispersion formula. The influence of disturbances in the air surrounding the flame on its axial symmetry is discussed. The criterion for the reliability of the research results is a comparison of the hilbertograms obtained in the experiment and the reconstructed hilbertograms.
