摘要：
In order to study the fragmentation shape and development track of fuel jet atomization process，and realize the accurate numerical simulation of fuel atomization process，atomization characteristics of a direct jet in a cross flow were numerically investigated. A couped Volume-of-Fluid（VOF）and discrete phase model （DPM）method was adopted to study the deformation and development of jet in the process of primary breakup，and to track the spatial distribution characteristics of Sauter mean diameter（SMD）of fuel droplets in the process of secondary. The adaptive mesh refinement（AMR）technique was applied to accurately capture the liquid structures and wave behaviour on liquid surface. The numerical results show as follows：column breakup and surface shearing breakup are dominant in primary breakup process of liquid jet. Breakup modes are highly influenced by Weber number，and the jet trajectory is obviously affected by the momentum ratio of liquid to gas. The fuel jet trajectory and droplet spatial distribution are in good agreement with the classical empirical relations and experimental data under different aerodynamic inlet conditions. © 2023 Journal of Propulsion Technology.
