Performance improvement of a nanofluid solar collector based on direct absorption collection (DAC) concepts

Progress of nanofluid application in solar collectors: A review

“…The study established that MWCNTs are highly absorbing among the majority of the solar spectra, allowing nearly 100% solar energy absorption at a very low concentration and a small collector volume. Luo et al [137] did a simulated study on the performance improvement of a nanofluid solar collector, based on the DAC concept. Based on the results of the simulated study, shown in Fig.…”

Heat transfer analysis and the effect of CuO/Water nanofluid on direct absorption concentrating solar collector

“…Menbari et al [20][21][22] conducted an experimental and analytical study of the optical properties of binary nanofluids for direct absorption in solar systems. Luo et al [23] studied the performance of a nanofluid solar collector based on direct absorption collection to show that solar collector efficiency could be improved by up to about 2-25% as a result of the use of nanofluids. Lenert et al [24] presented a combined theoretical and experimental work to improve the thermal efficiency of high-flux direct solar receivers by using carbon-coated cobalt nanoparticles.…”

Performance evaluation of nanofluids in solar energy: a review of the recent literature

“…Luo et al [8] simulated the performance of a DAC solar collector with nanofluids using a 2D model by solving the radiative transport equations of particulate media and combining conduction and convection heat transfer equations. The nanofluid flows horizontally from right to left in a steady-state solar collector covered with a glass plate.…”
