Abstract: The paper presents the results of experimental study of heating and evaporation of TS-1 aviation kerosene and its surrogates (n-decane and SU4) in a high-temperature gas flow (gas temperature range is 450–750 K, gas flow velocity range is 0-6 m/s). The conditions for temperature and gas flow rate are established, under which it is possible to provide good agreement on the time of complete evaporation, the dynamics of changes in the sizes (radii) and average temperatures of droplets of traditional aviation fuels using the example of kerosene TS-1 and its surrogates (SU4 and n-decane). When processing videograms, we used our own image processing algorithms developed in the MATLAB software package.

Keywords: heating, evaporation, aviation kerosene, surrogate fuel.
