Review of solar thermal energy storage materials

Analysis of Heat Pipe Filled with Several Oxide Nanofluids on the Start-Up Process

“…Figure. 6 shows the temperature difference distribution between the bottom of the evaporator section and the top of the condenser section of the heat pipe using Al 2 O 3 -water, CuO-water and SiO 2 -water nanofluids. It can be seen from figure.6 that the temperature distribution curve increases at first, then decreases as time goes by and stabilizes finally for different working fluids.…”

“…Rhi [4] measured the heat transfer performance of Ag-water nanofluids in a two-phase loop thermosyphon. Peng [5,6] studied the start-up performance, heat transfer coefficient and axial heat flow rate of the heat pipe when Al 2 O 3 -water nanofluids were used as the working medium. Huang [7] compared the start-up performance, temperature distribution and heat output for the heat pipe using ZnO-water, SiO 2 -water, Al 2 O 3 -water and TiO 2 -water nanofluids, respectively.…”

A review of metallic materials for latent heat thermal energy storage: Thermophysical properties, applications, and challenges

“…Metallic PCMs are good candidates to compete with salts in high-temperature applications because of their high volumetric heat of fusion and excellent thermal reliability [21,30,35]. The hightemperature applications are generally associated with concentrated solar power plants, solar energy storage, steam generators, industrial waste-heat recovery.…”

“…In the high-temperature range, mainly for solar LHTES applications, numerous review papers [21,[31][32][33][34][35][36][37][38] reported the thermodynamic properties obtained by [29,30] and highlighted their clear advantages of MPCMs in applications for medium and high temperature. In the low-temperature range, few metallic materials are presented in review papers [21] [37,[39][40][41].…”
