摘要

The interaction between crossflow and liquid jets is common in engineering applications, such as in gas–steam catapult power systems and supersonic ramjets. Studying the atomization process of liquid jets in crossflow has significant engineering value. In this work, high-speed photography was used. The experimental results indicate that factors such as airflow velocity, temperature, jet velocity, temperature, and nozzle diameter can affect the depth of jet penetration. Considering the influence of various factors, an empirical formula for calculating jet penetration is obtained. The results can support the design of gas–steam catapult propulsion systems and be extended to other applications, such as supersonic ramjets.
