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
