Published: March 4, 2024

This study explores the influence of Zinc Oxide (ZnO) nanofluids on solar water heaters with Dimple Tubes and Helical Twisted Tape (DTHTT) surfaces. The helical twisted tape design enhances turbulence, improving nanofluid mixing thermal exchange. Computational fluid dynamics (CFD) validates efficiency parabolic trough heater (PTSWH) emphasis light concentration feed flow velocity. Optimal conditions include a 0.3% ZnO volume concentration, mass rates between 1.0 kg/min 5.0 kg/min, copper-type tapes. Experimental results reveal Nusselt number enhancements 15.1% 20.96% at H/D = 10, 16.72% 32.12% 3, for nanofluid, Reynolds numbers from 3000 to 8000. arrangement 3 exhibits increased mixing, leading higher convective heat transfer. Friction factor 8000 are 0.26% 0.38%, respectively, compared base fluid. At 3.0 rate, increases 39.25%, 13.25% gain over plain model shows ±3.24% deviation expected friction factor, total ±1.2% discrepancy experimental simulated findings, remaining within an acceptable range.
