Abstract

The interplay between lateral airflow and liquid jet is extensively utilized in many engineering scenarios, including steam-power gas catapult systems. It is of paramount engineering interest for the fragmentation phenomena of jet in crossflow. This study establishes a jet test system and observes the flow characteristics resulting from water jet and crossflow interaction by utilizing the Schlieren method. The effects of inflow and outflow parameters on water jet penetration depth are extensively examined by evaluating parameters such as the gas-to-liquid momentum ratio, nozzle dimensions, and temperature. This study focuses on jet trajectory patterns and establishes mathematical correlations through penetration depth measurements that yield predictive equations for jet behavior.
