摘要：
A lattice Boltzmann model is developed for investigating the heat conduction process inside the three-dimensional random porous media. Combined with the algorithm for the reconstruction of the three-dimensional porous media, this model is used to investigate the transient heat conduction process inside the porous wick of CPLs/LHPs, which is vital for analyzing the startup stability of a CPL/LHP. The temperature distribution inside the porous wick is obtained and the influence of the porosity and the heat load on the conduction process also is investigated using the present model. The present model is applicable to predicting the effective conductivity of such a complex structure.
