Practical analysis for the characteristics of a tubular solar collector by aluminium oxide nanofluid and a reflective electronic curtain Available to Purchase

In this manuscript, two strategies for increasing the efficiency of solar vacuum collectors are investigated and analyzed. The first way involves installing a reflecting solar louver in front of the solar vacuum collector controlled by the solar panel system. It is possible to enhance the quantity of solar radiation reflected in the vacuum collector by using this curtain. The curtain is programmed to move in the same direction as the sun’s rays, and the Nano fluid’s temperature determines the reflectors’ movement. The aluminum oxide Nanofluid with a diameter of 70 nm is used in the second procedure, combined with distilled water. Three different flow rates of 30, 50, and 60 L/m were employed in the experiment, each with one of three different volume concentrations: 1, 3, and 5% by volume. Results showed that the solar vacuum collector’s thermal properties improved by 14.58 percent when using a sun-reflecting louver and Nano-liquid. Alternatively, without the sun-reflecting louver, progress was 9.61%. Nanofluid outperforms distilled water in thermal efficiency and performance. Installing the reflecting solar louver increases the quantity of solar energy reflected onto the solar vacuum collecting tubes, increasing efficiency. Programming lets it follow the sun.
