The distribution of temperature field and thermal ablation effect were solved for continuous laser irradiated rolling target under tangential air flow.Firstly,considering the influences of tangential air flow,solid-liquid phase change and target rolling,the 3D transient heat conduction equation was given in cylindrical coordinates,and the thermal ablation model of laser irradiated rolling target was established.Secondly,according to material state transforming relationship among solid-state,mushy-state and liquid state,an improved element deletion method was put forward to deal with boundary moving during ablation.The finite volume method was adopted to solve the thermal ablation model.Finally,the influence of target rolling velocity on temperature field distribution and thermal ablation effect was analyzed by numerical simulation.The results show that the maximum depth of ablation decreases and ablation area on cylindrical surface increases with target rolling,which lead to temperature field changes.
