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复合介质中的二维瞬态热传导问题。所提出的方法是基于表达的瞬态传导热传递方程的解决方案，在域与温度相关的材料性能，作为两个解决方案的组合：贝塞尔函数和积分的周边温度。所提出的方法用于求解热扩散率与温度相关的复合层状材料的瞬态传导。与其他使用传统的有限元方法获得的结果进行比较。在非均匀域（复合层状材料）的传热实验结果证明所提出的方法的性能。
A novel mesh-free Monte-Carlo method for two-dimensional transient heat conduction in composite media with temperature dependent thermal properties is presented. The proposed approach is based on expressing the solution of the transient conductive heat transfer equation, in domains with temperature-dependent material properties, as a combination of two solutions: Bessel functions and integrals of peripheral temperature. The proposed approach is used to solve transient conduction in composite layered materials with temperature dependent thermal diffusivity. Results are compared against others obtained using a conventional finite element approach. Experimental results for heat transfer in a nonhomogeneous domain (composite layered material) are presented to demonstrate the performance of the proposed approach.
