| Sumari: | Title screen In this research, we measure the temperatures of the non-combustible component (water) in a fuel droplet by 2-Color LIF before its micro-explosive fragmentation. We use two types of droplets based on water and tetradecane: a two-component immiscible droplet with water in the core and tetradecane as the envelope; a pre-mix emulsion. In both cases, the relative volume fraction of water in a droplet is 9%, and that of the combustible component (tetradecane) is 91%. To provide the micro-explosive dispersion of droplets, we use a scheme with the conductive heating in the range of 250 °C to 550 °C. Using the high-speed 2-Color LIF technique, we observe the coalescence of water micro-droplets in emulsion droplets and intense disruption of the water core in a two-component droplet when heated. The temperature in two zones are measured. The temperature difference may range from 1 °C to 10 °C. In the puffing regime, the droplet temperature is 1–3 °C higher than in the micro-explosion regime at the same temperatures of the heated metal substrate surface. Within a certain interval of the heating time, the temperatures of water in a two-component droplet and in an emulsion droplet become comparable.
