| Ամփոփում: | Title screen The study explores the temperature recording of the ice particle – liquid layer system by means of Planar Laser Induced Fluorescence. Before the experiment, water droplets with fluorophore were frozen until they became ice particles. The most promising dyes for water were used: Rhodamine B and Rhodamine 6G. As ice particles were heated, the fluorescence of fluorophore was recorded. Three types of ice melting conditions with various concentration of dyes were investigated: without external influence (at room temperature); exposing to local heating by a laboratory burner; using convective heating by a blowing air flow. The curves were obtained for the fluorescence of fluorophores versus temperature in each of the three types of experiments. The specific behavior of the dye was analyzed when exposing it to low temperatures, i.e., crystallization. Typical water temperature differences during ice melting were determined. The ranges of validity and accuracy, as well as specific aspects of using Planar Laser Induced Fluorescence during two phase transformations – melting and evaporation – were established.
