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 Lattice Boltzmann method to calculate heat insulation performance parameters such as temperature distribution, and thermal conductivity.

Abstract: The present invention is directed to an in-house space antistatic & static electricity leakage method, comprising that multilayer different antistatic materials coated onto walls, ceilings, ground and glass doors, or windows so as to achieve the automatic compensation of antistatic action, wherein wall, ceiling and ground each is composed of base layer, interlayer and top layer. Said base layer is filled up using filling material containing antistatic material, scraped smooth, and compacted for 1-3 times; the interlayer can be coated with a thickness of 0.3-2 mm with antistatic interlayer material having decorative effect for 1-3 times. The top layer is coated 0.1-0.4 mm thick with antistatic covering material for 2-3 times. The glass door or window is coated with a thickness of 0.1-0.3 mm with transparent antistatic material for 2-8 times.
