Numerical Study on Performance of Flat Tube with Water Based Copper Oxide Nano fluids

The purpose of this research is to conduct a numerical analysis of the performance of a flat tube filled with copper oxide nanofluids. A virtual 3D replica of a flat tube was used to pass the nanofluid through. The benefits of employing nanofluids rather than pure base fluid were assessed. The thermophysical characteristics of the nanofluid were computed using experimentally obtained correlations (function of temperature and volumetric concentration nanoparticles). The heat transmission performance of a flat tube was found to improve when particle concentration, temperature, and Reynolds number increased. With increasing volumetric concentration of nanoparticles and Reynolds number, the pressure loss across flat tube increased. The performance of nanofluids has been numerically compared to that of a base fluid. The thermophysical properties of nanofluids were evaluated using well-developed models for each thermophysical parameter at varied nanoparticle concentrations, ranging from 0.1 to 0.5 percent. The heat transfer performance of the compact channel was examined, and it was observed that when the nanoparticle concentration grew, the heat transfer rate of the compact channel increased dramatically. At the same temperatures, the heat transfer rate of the nanofluids was roughly 23% higher than that of the base fluids.
