| 摘 要： | 通过1053 nm重频脉冲激光辐照铝合金板和铝合金/水结构实验,初步研究了水的存在对铝合金板温度变化的影响。采用有限元方法,计算了脉冲激光辐照下铝合金板和铝合金/水结构中的温度场变化。数值结果和实验结果基本相符,水的存在加速了热扩散,延缓了铝合金板的温升。

| Abstract: | Experiment is carried out to record temperature history of aluminum alloy slab for single aluminum alloy slab and aluminum alloy chamber containing water,both irradiated by 1053nm pulsed laser.Finite element models are set up to simulate the temperature field variation process,and simulation results agree well with the experimental results.Our work shows that the water in the chamber accelerates thermal diffusion process inside the aluminum alloy slab thus delaying the temperature rise inside the slab. |
