The invention provides a three-dimensional numerical simulation method for droplet atomization in a transonic flow process of compressible fluid, and relates to the field of fine atomization. According to the invention, simulation of a process from generation of a transonic flow field to breaking of liquid particles in the transonic flow field in a three-dimensional model space is realized by using a numerical simulation method; the established numerical model and calculation steps can be used for visualizing and analyzing three-dimensional states of a liquid crushing process, a crushing mechanism, particle position distribution, particle size distribution, particle speed distribution and the like in transonic flow fields in spray pipes with different shapes and based on a Laval mechanism.The established numerical model provides accurate prediction and most intuitive theoretical basis for crushing processes and results of different liquid particles in flowing under different airflow inlet and outlet boundary
