Numerical Study of Heat Transfer Enhancement for Mono and Hybrid Nanofluids Flow in a Straight Pipe

In recent years, there has been an increasing interest in heat transfer enhancement using nanofluids channels due to current devices become smaller and more compact are expected perform better. Thus, we attempt introduce hybrid flow a straight pipe Ansys Fluent software. The simulation was prepared with certain specific parameters such as the hydraulic diameter is set at 10mm, continuum, Reynold number range of 5000 30000, k-e turbulent model used this simulation, inlet temperature 297 K, uniform along 313 K. This study carried out on Al2O3+Cu / water analyse thermal improvement friction factor occur pipe. Then, numerical results obtained were compared between mono nanofluids. It found that 1% 4% indicate significant increase Nusselt 17% 24% respectively nanofluid 2% 5.6% base fluid. Whereas remains similar for all However, performance evaluation criterion (PEC) shown remain lower than
