Thermal property characterization of a low melting-temperature ternary nitrate salt mixture for thermal energy storage systems
Molten salts have better thermal properties than synthetic mineral oil, and hence they can be directly used as heat transfer fluids in solar power plants, but in practice their direct applications as heat transfer fluids are constrained due to their high freezing temperature points. In this paper, a...
