In this paper, a three-dimensional (3D) randomly packed bed model is established to research the filtration combustion process. 3D numerical simulation of premixed combustion in the randomly packed bed is carried out, and the temperature distributions and flame propagation characteristics are predicted and discussed. Simulation results show that the change rules of the temperature field and the flame surface in the random model are consistent with the classical theory, and the stochastic packed model is more promising for numerical simulation of filtration combustion in comparison with the traditional regular structures.

随机填充床中丙烷-空气过滤预混燃烧过程的数值研究

在本文中，建立了一个三维（3D）随机填充床模型来研究过滤燃烧过程。对随机填充床预混燃烧进行3D数值模拟，预测并讨论了温度分布和火焰传播特性。仿真结果表明，随机模型中温度场和火焰面的变化规律与经典理论一致，与传统的规则结构相比，随机填充模型对过滤燃烧的数值模拟更有希望。
