Phase Change Material of Copper–Germanium Alloy as Solar Latent Heat Storage at High Temperatures
نویسندگان
چکیده
A copper–germanium alloy (Cu–Ge alloy) was examined as a phase change material, at temperatures exceeding 600°C, for latent heat storage in solar thermal applications. First, the thermo-physical properties of Cu–Ge were using differential scanning calorimetry, thermomechanical analysis, and laser flash analysis. Second, to evaluate response reliability alloy, cyclic charge/discharge under various conditions. The alloys obtained after tests their chemical compatibility with stainless steel container an electron probe micro analyzer. elemental distribution each evaluated performance tests. Finally, high-temperature test candidate materials material vessel [stainless (SUS310S), Inconel625, silicon carbide (SiC), alumina (Al2O3)]. exhibited significant potential next-generation power plants because it demonstrates advantages, including superior capacity temperature 644°C, coherence diagram, quick response, satisfactory behavior modes, thermodynamically stable metallographic structure, non-reactivity ceramic (SiC Al2O3).

متن کاملEffect of Using Nano Encapsulated Phase Change Material on Thermal Performance of Micro Heat Sink
The aim of this paper is to enhance thermal performance of a microchannel heat sink by using nanoencapsulated phase change material (NEPCM) slurry as a cooling fluid instead of pure fluid. A threedimensional model of a circular channel using water slurry of NEPCM was developed. The results show a significant reduction in the mean fluid temperature along the channel and heat sink wall temperatu...
