Two-dimensional simulation for the effective thermal conductivity of heat-sealing porous material

A simple and effective method was presented for two-dimensional effective thermal conductivity of heat sealing porous material here, which can be used to simulate the structure of pore distribution in any form range between solid-phase continuous and discontinuous media. By analogy to porous flow model, we could get a kind of correlation coefficients. According to the relationship of the series and parallel thermal resistance, the effective thermal conductivity of the four computable models were calculated, Then the effective thermal conductivity of the specific model was obtained by the correlation coefficient. This method can control some important parameters affecting the effective thermal conductivity a lot, such as the porosity, pore size, pore distribution and temperature, Moreover, it has taken the effects of radiation into account and shares simple simulation and fast calculation. The simulation results match to the experimental results in the literature well, verifying the correctness of this method.
