Thermal performance enhancement of nanofluids based parabolic trough solar collector (NPTSC) for sustainable environment

Due to rapid industrialization and urbanization, upward rise in carbon emissions the atmosphere, depletion of fossil fuel gas reserves have forced find alternative renewable energy resources, where solar is one most promising source. Parabolic trough collectors (PTCs) can effectively transfer high temperature tube receiver upto 400 °C. In this study, Computational Fluid Dynamics (CFD) analysis used analyse effect multiple working fluids on efficiency PTC. Two different types nanofluids for analyising thermal PTC through CFD simulations, are Alumina Copper-oxide nanofluids. The concentration Copper Oxide was kept 0.01% calculated at two mass flow rates i.e., 0.0112 Kg/s 0.0224 Kg/s. highest 13.01 13.1% using Al 2 O 3 as rates, while CuO has an 13.92% 14.79% these rates. behaviour absorber material distribution steel, copper aluminum also investigated. Changing from steel increased outlet fluid. maximum output achieved 311 K showed lower 307 308 fluid outlet. Furthermore, impact tube’s length fluid’s studied. nanofluid higher both compared alumina nanofluid. Accordingly, a comparison made results with experimental findings literature. based PTCs system method sustainable environment applications.
