摘要:
采用数值模拟方法分析研究了激光点火过程中能量源与含能材料的作用机理以及影响点火的因素。以激光点火的热作用机理为基础,结合声光理论建立并求解了含能材料激光点火过程强瞬态热传导-气动力耦合模型。通过计算分析得到了激光能量、光斑面积、含能材料光反射率和吸收系数等因素对含能材料表面温度和激光点火过程的影响。该研究结果有助于优化点火参数,提高激光点火的可靠性。
Abstract:
To study the reaction mechanism of energy sources and energetic materials in the laser ignition process and the influence of different factors on the ignition,the simulation of the laser ignition is carried out.On the basis of the laser ignition thermal mechanisms and the photoacoustic theory,the laser ignition model of energetic materials coupling heat conduction and gas dynamic is established.The effects of different factors on the ignition processes including the laser energy,the beam radius,the reflectivity and the thermal conduction of the energetic material are simulated and calculated.The research results are helpful for optimizing the ignition parameters and increasing the reliability of the laser ignition system.
