Flow of water-based Cu, CuO, and Al2O3 nanofluids heated with constant heat flux between micropipe

This study aims to analytically measure the fully developed laminar flow and heat transfer water-based nanofluids, Cu, CuO, Al2O3, within a micropipe with constant flux, under temperature jump slip rate boundary conditions. Knudsen number, nanoparticle volumes, ratios of liquid layer thickness particle radius are assumed, 0, 0.02, 0.04; 0%, 4%, %8, 0.1, 0.2, 0.4, respectively. The findings suggest that adding nanoparticles area has significant effect on both velocity field transfer. There is decline in at core walls area, due increase solid volume after Nusselt number significantly proportional radius. Among nanoparticles, used as nanofluids micropipe, Cu found be one highest enhancement, followed by
