Abstract :
A numerical analysis of the heat transfer and pressure drop of a water-based ?-Al2O3 nanofluid gasketed plate heat exchanger was undertaken to specify its optimum conditions. The results showed that, based on the heat exchanger’s performance index, the optimal volume concentration of ?-Al2O3 is approximately 0.016. The heat transfer rate at the optimal concentration of nanofluid is approximately 12.3% higher than that of pure water (base fluid), while the pumping power increased by 1.15%. Increasing ? values from ?=0.016 to ?=0.028 will result in a 1% improvement in the heat transfer rate.
