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.
