提出了一种新的无网格蒙特-卡罗方法，用于求解热物性随温度变化的均匀介质到非均匀多层复合材料的三维瞬态热传导问题。新的贡献包括一个新的算法来考虑从源到汇的热扩散率的影响，在计算粒子的步长（粒子表示为从每个源发出的能量束），和三维周边积分的推导来考虑汇周围的材料特性对其温度的影响。使用所提出的方法开发的模拟进行比较，对实验测量和有限元模拟的结果。
A new solution for the three-dimensional transient heat conduction from a homogeneous medium to a non-homogeneous multi-layered composite material with temperature dependent thermal properties using a mesh-free Monte-Carlo method is proposed. The novel contributions include a new algorithm to account for the impact of thermal diffusivities from source to sink in the calculation of the particles’ step length (particles are represented as bundles of energy emitted from each source), and a derivation of the three-dimensional peripheral integration to account for the influence of material properties around the sink on its temperature. Simulations developed using the proposed method are compared against both experimental measurements and results from a finite element simulation.
