针对有较长热驰豫时间的材料在表面受到激光脉冲照射时的非Fourier热传导问题,利用Laplace、Hankel变换及其逆变换,给出了一个半解析解.数值仿真表明,该半解析解能够清晰显示非Fourier热传导问题中的热波现象.
The non-Fourier model of heat transfer as a laser pulse irritating on surface of material with large thermal relaxation time is considered.A new semi-analytic solution is derived by using Laplace, Hankel and their inverse transforms.By numerically simulating the solution,the wave form behavior of temperature can be seen clearly.
