... (circulation mode), and effect of carbon quantum dots (CQDs) water-based nanofluids, nanoparticles volume concentration, and packing factor (β c ) of the PV module has been studied by developing generalized thermal modeling of the system (special cases). Overall, 41.1%, 21.52%, 22.01%, and 10.01% rise...

... as a nanofluid for achieving the required cooling process. The particle concentrations and sizes are investigated to record their effect on heat transfer and pressure drop in the developing and developed regions. The research was performed using ansys cfd software with two different approaches: the single phase...

...Jagteshwar Singh; M. K. Mittal; Vikrant Khullar In the present endeavor, a conventional single-slope solar still has been modified to improve its performance by coupling it with a novel nanofluid-based volumetric absorption solar collector (NBVASC). A low-cost and thermally stable nanofluid...

... are used, a plain copper tube and an evacuated glass tube embedded with a copper tube. Surfactant-free multiwalled carbon nanotubes–Therminol55 nanofluid with concentrations of 25, 50, 75, and 100 ppm are used in this study. The characterization of the nanoparticles and nanofluids is presented...
