摘要
切向气流作为一种环境因素会对激光辐照效应产生重要影响,近年来国内外学者对切向气流作用于激光辐照效应进行了广泛研究,主要集中在不同性质的气流环境、不同强度的切向气流对激光辐照效应的影响,其影响因素主要包括促进氧化反应、增大换热系数、空气动力学等,分析了各因素在不同条件下影响激光辐照效应的相互耦合作用。但对切向气流影响激光辐照效应的材料研究还不够广泛,对空气动力学引起靶材融化前破裂现象的分析不够清晰,这些都有待进一步研究完善。
Tangential airflow as a kind of environmental factors can impact on the laser irradiation. In recent years,the tangential airflow effects on laser irradiation are extensively studied by some scholars at home and abroad,including the influence of different natures of the airflow environment, different intensities of tangential airflow on laser irradiation. Its influence factors mainly include oxidation reaction promotion, convective heat transfer coefficient increase and aerodynamics. The couple interaction between the factors is analyzed. But the material research of tangential airflow laser irradiation effect is not enough, and the analysis of fracture before melting is not clear, which need further research for improvements.
