چکیده
|
A numerical analysis of the heat transfer and pressure drop of a water-based γ-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 γ-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 ϕ values from ϕ=0.016 to ϕ=0.028 will result in a 1% improvement in the heat transfer rate.
