Thermal properties, flow and comparison between Cu and Ag nanoparticles suspended in sodium alginate as Sutterby nanofluids in solar collector

Solar energy's unrestricted accessibility aids in environmental sustainability and renewable technology. Parabolic trough solar collector (PTSC) is a well-established, low-cost talent that is utilized in a variety of solar technical applications. Current research focuses on thermic radiation, slippage velocity, sucking (injection), and convective boundary constraint to improve the heat transmission of PTSC in the existence of magnetic force. Entropy analysis is probed in a penetrable material of Sutterby nanofluid (SNF) flow past an exponentially extending horizontal plate that features PTSC. The study looks at two types of nanofluids: copper-sodium alginate (Cu-SA) and silver-sodium alginate (Ag-SA). To transform partial differential equations (PDEs) to nonlinear ordinary differential equations (ODEs) with associated boundary constraints, enough similarity variables are used. To get an approximate solution to reduced ODEs, an efficient Keller-box approach is used. The results are visually represented and analyzed in terms of physical factors. According to major discoveries, raising the Brinkmann and Reynolds numbers increases the total system entropy. The Sutterby nanofluid parameter improves the heat rate of the Parabolic Trough Solar Collector. When the parameters are changed, the thermal efficiency of Cu-SA increases by 1.7% at the least and 4.8% at the most.
