Experimental investigation on photothermal conversion performance of MWCNT-DW/EG nanofluids for low-temperature direct absorption solar thermal energy systems
Applied Thermal Engineering(2023)
摘要
•Photothermal properties and factors on conversion performance were evaluated.•Optimum concentration and pH value were found to be 100 ppm and 7, respectively.•Maximum temperature rise of 12.75 °C was achieved compared to the base fluid.•Efficiency of nanofluid DASC was 26.54 % higher than ETSC under the same condition.
