主 题:solar collector hybrid nanofluids solar water heating system solar simulator thermal efficiency
摘 要:Due to the depletion of conventional energy sources and its limitless resources,solar energy is currently being considered as a viable alternative,especially for water heating *** thermal performance of multilayer solar collectors for water heating systems can be improved further by introducing hybrid nanofluids as advanced *** study demonstrates the utilisation of hybrid nanofluids in heating systems by employing a multilayer absorber solar *** SiO2–TiO2 hybrid nanofluids at volume concentrations up to 2.0%were tested at various flow rates(1.7 to 3.7 LPM)and solar radiation intensities(250 to 1000 W/m2).The thermal performance of the solar collector was assessed by measuring the temperature variation,heat loss,and overall efficiency of the *** the optimal volume concentration,the temperature difference for solar collectors employing SiO2–TiO2 hybrid nanofluids increased *** optimal volume concentration of 1.5%yields a maximum temperature difference of 9.5°*** addition,the efficiency and fluid temperature of the solar collector containing hybrid nanofluids have been enhanced by 22%and 37%,*** SiO2–TiO2 hybrid nanofluids with the optimal volume concentration of 1.5%were therefore recommended for maximum efficiency in the solar collector.
