Abstract
Based on the heat regulation and control idea of metamaterials,a novel two-dimensional metamaterial thermal protection structure was devised.Compared with conventional thermal protection structures,a metamaterial layer consisting of high thermal conductivity materials and phase change materials was added to realize directional heat transporting and thermal energy store and management.Finite element method was adpoted to build the numeri-cal simulation model.The local high temperature produced by uneven load of Gaussian distribution in space,and temperature oscillation caused by alternating load and step load in time were analyzed in detail.The simulation re-sults indicate that the proposed metamaterial thermal protection structure can effectively suppress local high tempera-ture caused by uneven load in space.Moreover,the metamaterial thermal protection structure is able to weaken the temperature fluctuation and shock caused by alternating and step thermal load.In the same load cases,the highest tempature on the outer surface of metamaterial thermal protection structure is reduced by 15.3％and the amplitude of stationary temperature oscillation was reduced by 48.6％,compared with the conventional thermal protection structures.Therefore,by introducing a metamaterial lay,not only is the thermal protection capacity of the thermal protection structures improved,but also their thermal shock resistance is increased,which provides an important reference for design of efficient thermal protection systems in future.关键词
