The paper presents the results of an experimental study on propagation dynamics of the self-sustained evaporation front in a large volume of Freon-R21 with the addition of SiO2 nanoparticles. The experimental data on propagation velocity and structure of evaporation fronts were obtained; the spectral analysis of fluctuations of the evaporation front interface was carried out. The characteristic frequencies and amplitudes of interface fluctuations were determined depending on the velocity of evaporation front propagation. It was shown that the addition of nano-sized particles significantly affects the front velocity and character of interface fluctuations.
