摘　　要：为了研究目标高速运动情况下,高速气流对流换热对激光辐照效应的影响,通过编制了高速目标激光辐照温升效应仿真程序。考虑了对流换热因素和材料参数随温度的变化。为了保证仿真结果的可信性,从理论和实验两方面对仿真模型的算法和参数进行了验证。仿真计算结果表明,对流换热在一定程度上减弱了激光辐照下材料的温升效应,但针对激光辐照下的其它效应,对流换热的影响程度与具体应用有关。In order to investigate the influence of convection to laser radiation effect for high speed target, a sim- ulation code for laser heating effect is developed, which considers the convection of high speed flow and the non - constant matter properties. The simulation model is validated using a theoretical example and an experiment to ensure its creditability. Simulation result indicates that high speed flow convection can reduce the laser heating effect to a certain extent, but for other effect under the laser radiation, the influence of convection effect depends on application background.
