The combined radiation and conduction heat transfer in multilayer perforated insulation material (MLPIM) using in space has been investigated. The model for the calculation of temperature field in MLPIM and the model of inner radiation have been presented according to energy balance equation. The difference equations have been solved by iterative method combining with ADI method. Comparison between the numerical results by the models in this paper and the experimental results in the literature shows that the models are feasible to be applied in engineering. The effect of the main parameters such as layer density, screen emissivity and perforation coefficient on the thermal performance has been analyzed. The study on the performance of MLPIM will present active instruction to improve the insulating performance and accomplish optimum design of MLPIM.
