Numerical investigation of the evaporative cooling of water droplets in a high-temperature gas flow (temperature above 1000°C) has been carried out for two limiting regimes: a continuous medium and a free-molecular regime. The results of modeling have shown that with a small content of water vapor in the flow, due to evaporative cooling the droplet temperature attains a stationary value that is lower than the stream temperature by hundreds of degrees.
