Study on thermal response of aluminum alloy plate subjected to airflow and laser irradiation
为了获得激光加工等应用中气流环境激光辐照材料的热响应特性和熔穿规律,采用面热源近似和不定常热传导分析方法构建了包括热传导、对流换热、熔化烧蚀等主要机制的物理模型,并通过实验校核后进行了气流环境激光辐照铝合金热学响应定量评估,获得气流环境不同激光功率密度下铝合金靶板温升和烧蚀熔穿规律.结果表明,相同靶参数下,熔穿时间随着激光功率密度增加而急剧减小,并且熔穿时间变化规律与热平衡积分方法气化烧蚀模型结果一致;不同条件下熔穿时间显示,在激光功率密度较小(…查看全部>>
In order to obtain the thermal response and melting through characteristics of materials irradiated by high energy laser with airflow environment in field of laser processing and other applications,a physical model considering the mechanisms of heat conduction,convective heat transfer,melting and ablation was constructed by using the approximation of plane heat source and unsteady method.The model was validated by experiments and was used for evaluating quan…查看全部>>
