摘要
基于非Fourier热传导波动型方程,采用镜像方法和波函数展开法,研究了固体介质 中亚表面圆柱缺陷的热波多重散射问题．首次基于热传导波动模型给出了热波散射问题的一般解． 温度波由调制光束在材料表面激发,缺陷表面的边界条件为绝热．具体分析了结构几何参数和物理 参数对温度分布的影响,并给出了温度变化的数值结果．本研究结果可为红外测试技术、热波成像 技术等提供理论基础和参考数据．
In this paper, based on non - Fourier＇ s equation of heat conductivity, using image method and the expansion method of wave functions the thermal wave scattering of subsurface cylinder is investigated. A general solution of scattered waves based on wave equations of heat conduction is given. The effect of different physical parameters on the temperature distribution is analyzed. The thermal waves are excited at surfaces of opaque materials by modulated optical beams. The circular cylinder is taken as a cavitv with thermal insulation conditions.
