“…Currently, researchers conducting simulations of laser ablation processes prefer to study the evolution of the internal temperature field, velocity field, and ablation craters of laser ablation, in addition to capturing the material loss after laser action. 21 The numerical models are no longer satisfied with a simple mass conservation criterion. Many models are beginning to take surface tension, 22 evaporative recoil, phase explosion mechanisms, 23 and plasma expansion 24,25 into account so as to more accurately predict the morphology produced by laser ablation.…”

. A three-dimensional numerical model was established based on the volume of fluid method. The thermal-fluid process in the laser cleaning thermal barrier coatings is analyzed in detail. The effect of scanning speed on the cleaning process was investigated by tracing the migration position of the air-coating phase interface, with consideration of gravity and vapor impact pressure. It was demonstrated that phase change of the zirconia coating is dominated by the vaporization-evaporation process when it is ablated by a millisecond laser; the ablation process of the C263 alloy substrate is a solidification-melting process. The bulge at the edge of the gully will affect the morphology of the gully by influencing the temperature distribution.
