摘 要: 將高溫熔融鹽相變蓄熱材料和陶瓷固相蓄熱材料進行復合，成功地研制成了能快速吸熱和放熱且蓄熱密度高、蓄熱量大的新型復合蓄熱材料。分別以Al2O3, MgO, SiC為代表的陶瓷材料與60LiF-40NaF, 50LiF-50KF, 60.1NaCl-39.9MgCl2，LiH等為代表的10余種高溫熔融鹽材料為復合研究對象，對復合蓄熱材料的蓄熱密度等與溫度、復合材料中熔融鹽的含量、材料種類間的關系進行了數(shù)值模擬研究，得到了對復合材料的優(yōu)化設計具有指導意義的結(jié)論。

Abstract:A new technique was developed to combine sensible ceramic heat storage material with molten salt latent heat storage materials to composite heat storage materials which will have some advanced thermal properties, such as fast heat storage rate, fast heat removing rate, big heat storage density. And the numerical simulation on optimum combination of ceramic and molten salt for new composite heat storage materials was reported. Effect on the heat storage density of new composite heat storage materials was studied for temperature, kinds of ceramics, molten salts and the mass rate of molten salt.
Key words: composite heat storage material; ceramic; molten salt; numerical simulation
