Abstract

A thermal effect model is presented in this paper, with the background of ground-based laser irradiating moving and rotating target in the air. Firstly, the encounter scene of laser irradiating target is assumed, and the main parameters of laser and target are given. Secondly, the calculation model of irradiating parameters is derived, including irradiating area, power density distribution and convection heat transfer per unit area. Thirdly, the thermal effect model is established to describe heat conduction and thermal ablation during laser irradiating. Finally, the thermal effects are calculated by assuming the parameters in encounter scene of laser irradiating target. As shown in the example, the thermal effect model can minutely describe the temperature field and ablation results of moving and rotating target irradiated by laser.
