In order to study the influence of target distance, angle, flow rate and other cleaning parameters on the cleaning effect in dry ice cleaning technology, this paper mainly uses FLUENT software to simulate and record the dry ice and air two-phase flow field formed by cylindrical spray gun under different cleaning parameters. The simulation results were processed by the control variable method, and the velocity changes of dry ice particles on the surface of the cleaned object and the central axis of the spray gun under different cleaning parameters were compared and analyzed. Finally, it is found that the shorter the target distance is, the closer the angle between the spray gun and the surface of the cleaned object is to 90°, and the greater the flow rate of dry ice particles is, the greater the kinetic energy of dry ice particles reaching the cleaning surface is, which provides data support for finding the optimal cleaning parameters.
