| 摘 要： | 总结了亚音速切向气流在激光辐照典型金属靶过程中所起的作用,提出气流效应主要包括增大靶与外界环境的对流换热强度;移除靶表面的熔化层,加快烧蚀速率;促进靶的氧化反应,有利于靶的烧蚀;空气动力学效应导致靶在熔化之前就可发生破裂等几个方面。对上述气流效应进行了详尽的分析,同时指出应对氧化反应及热力联合效应进行更广泛的实验研究,获得更明确的规律性认识,以便建立统一的物理数学模型,从而为实际的工程应用提供参考。

| Abstract: | The effects of some metal targets subjected to the laser irradiation and tangential airflow are overviewed.It points out that the airflow usually affects the metal targets in such ways:cooling the targets,removing the melt layer,supporting the combustion reaction and breaking the target prior to melt-through.After analyzing on the airflow effects in details,it suggests that extensive experimental research should be performed for the combustion reaction and thermal-mechanical effect during laser irradiation.... |
