建立了描述闪电通道与复合材料结构热相互作用的物理模型。该模型包括：(I)闪电通道作为电流波形的函数的时空演化；(Ii)复合材料结构产生的临时和空间非均匀热流，其中热流是电流波形和瞬时闪电通道半径的显式函数；(Iii)层状各向异性复合材料的非线性暂态热传导问题，它考虑了材料性质的温度依赖性、扩展的闪电通道的移动边界以及与升华引起的瞬时物质去除相关的相变移动边界。将该模型应用于SANDIA 100m全玻璃基线风力机叶片(SNL 100-00)尖端玻璃纤维增强复合材料面板在雷击下的热损伤评估。
A physics-based model describing the thermal interaction between a lightning channel and a composite structure has been developed. The model includes: (i) spatial and temporal evolution of the lightning channel as a function of the electric current waveform; (ii) temporary and spatially non-uniform heat flux generated at the composite structure, where the heat flux is an explicit function of the electric current waveform and the instant lightning channel radius; (iii) nonlinear transient heat transfer problem formulation for layered anisotropic composites that accounts for temperature-dependent material properties, a moving boundary of the expanding lightning channel, and phase transition moving boundary associated with instantaneous material removal due to sublimation. The model is applied for evaluation of thermal damage of the tip glass fiber reinforced polymer matrix composite panel of the Sandia 100-meter All-glass Baseline Wind Turbine Blade (SNL 100-00) subjected to lightning strike.
