Controversial results have been reported for specific heat of conventional nanofluids and molten salt nanofluids. Some water-based and organic-based nanofluids showed decreases in specific heat, while molten salt-based nanofluids showed highly enhanced specific heat. In this study, we propose a distinct heat storage mechanism to explain enhanced specific heat of molten salt nanofluids and compare with the specific heat mechanism of conventional nanofluids.
