摘要
本文对一侧表面存在对流换热的薄层物料受高强度脉冲激光加热的双曲型热传导问题利用有限差分方法进行了数值求解。考虑激光的容积吸收,将高强度脉冲激光处理为沿光程指数衰减的内热源。本文对考虑容积吸收及对流换热的影响后双曲型热传导方程的计算结果进行了分析。
This paper numerically solves the hyperbolic heat conduction problem of a thin material which is heated by high-power pulse laser and has convection boundary condition in one side by the FDM method. Considering the volume absorption of the laser, this paper regards the high-power pulse laser as a heat source which decreases exponentially with its penetration depth. This paper analyzes the calculation results of the hyperbolic heat conduction formula with considering volume absorption and convection heat transfer.
