摘要：

This paper investigates the evaporation of a water droplet with a comparably sized solid nontransparent inclusion in a high-temperature (500-800 K) gas medium. Water evaporates from the free surface of the inclusion. During this process, intensive vapor formation occurs on the inner interface "water droplet - solid inclusion" with the subsequent explosive decay of the droplet. Experiments have been conducted using highspeed (up to 105 fps) video cameras "Phantom" and software "Phantom Camera Control". The conditions of the explosive vapor formation of the heterogeneous water droplet were found. The typical phase change mechanisms of the heterogeneous water droplet under the conditions of intensive heat exchange were determined.
