چکیده انگلیسی
Graphene oxide (GO) dispersed nanofluids were first explored to be used as working fluids for direct absorption solar collectors. The stability, optical absorption property, thermal-physical property and photo-thermal conversion performance of the GO/water nanofluids with different mass fractions of GO were symmetrically investigated. The sedimentation experiment and Zeta potential (ζ) analysis showed that the GO/water nanofluids not only possess excellent long-term stability but also keep stable at elevated temperatures. A remarkable enhancement in optical absorption property was observed for the GO/water nanofluids due to the dispersion of GO into water. The GO/water nanofluids exhibited an obvious improvement in thermal conductivity as compared with water. The photo-thermal conversion performance of the GO/water nanofluids were higher than that of water, and the highest efficiency was achieved by the one containing 0.02% of GO, which was 97.45% at 30 °C and 48.92% at 80 °C. The GO/water nanofluids with excellent dispersion stability, good optical absorption property and photo-thermal performance show great promise for use as the working fluids in low temperature direct absorption solar collectors.
