This study investigates convective heat transfer and the performance characteristics of a uniformly heated car radiator using Al2O3–Cu/water nanofluids. The experimental approach involves preparing nano-composite powders of Al2O3 and CuO suspended in water through a sonication process. Various combinations of these nanoparticles, with concentrations ranging from 0.1% to 1%, are examined alongside different flow rates from 3.5 to 4.5. The fluid enters the system uniformly at 50°C, and experimental results reveal varying Nusselt and Reynolds numbers at different concentrations and flow rates. Specifically, 1% CuO/water nanofluids exhibit slightly higher heat transfer coefficients compared to other volume concentrations and flow rates of Al2O3/water nanofluids. Empirical correlations for Nusselt number and friction factor align well with the experimental data. Additionally, Computational Fluid Dynamics (CFD) simulations are performed using ANSYS 18.0 Fluent to model the car radiator design, employing a coarse mesh and applying boundary conditions. The analysis shows laminar flow, and the CFD results are in close agreement with the experimental findings, depicting temperature, velocity, and pressure contours.
