In order to deeply study the specific characteristics of the cross-scale phenomenon of fragmentation and atomization in the process of transverse jet atomization, this paper uses the LES turbulence model and the VTD multiphase flow model to numerically simulate the transverse jet process and analyzes the corresponding results. It can better solve the cross-scale related problems and then obtain a more suitable research method for the phenomenon of transverse jet fragmentation and atomization. The study found that the liquid column gradually narrowed along the jet direction under the action of the lateral airflow, and the liquid column was increased by the force of the lateral airflow, resulting in the expansion form of the liquid column being curved downstream. As soon as the jet enters the flow field, it forms independent droplets under the action of the air flow. With the passage of time, the stripped droplets are further broken up to form droplet particles, which are transformed from liquid phase to Lagrangian particle agglomerates. When the jet is fully developed, the surface of the liquid column is broken near the outlet to form small droplets, and then the jet is broken in a columnar shape to form a large number of ribbon-shaped liquid filaments.
