Abstract: A method for numerical reconstruction and heat transfer characteristics evaluation of a microstructure of thermal barrier coatings containing microcracks includes the following steps: determining a simulation area and size settings, generating random microcracks with different morphological characteristics and placing the microcracks in the simulation area, and determining whether a space occupied by the microcracks reaches a porosity ratio of the preset microcracks, building a general pore model of thermal barrier coatings (TBCs) based on the QSGS method, reconstructing true mesoscopic morphologies of the TBCs, determining whether the preset volume fraction has been reached, and building a heat transfer analysis model based on the thermal 1,attice Boltzmann method to calculate heat insulation performance parameters such as temperature distribution, and thermal conductivity. Compared with the prior art, the heat transfer analysis model can restore a mesoscopic structure of the coating more truly and effectively.
