| 摘 要： | 用有限差分法对激光辐照下复合材料树脂基热解时的一维温度场模型进行数值求解,将数值模拟结果与相关文献中给出的实验结果进行对比.结果表明:考虑了对流传输效应的数值模拟结果比没有考虑对流传输效应的数值模拟结果与实验结果符合的更好,即热分解气体的对流传输对树脂基复合材料的温度场有较大的影响.因此,在不引入力学量的前提下,建立激光辐照下复合材料树脂基热解时的三维温度场模型时,需要考虑热分解气体的对流传输效应.

| Abstract: | The one-dimensional temperature field model of thermally decomposing resin composite irradiated by laser was solved with the commonly-used finite difference method.By comparing the simulation result with the experimental result which was reported by related literature,the influence of the pyrolysis gas convective transport on the temperature field of resin composite was studied.The analysis indicates that the simulation temperature field considering the convective transport of pyrolysis gas matches better t... |
