چکیده

In this paper, the characteristics of forced convection heat transfer in water-based nanofluids are studied by means experimental and theoretical analysis. Nusselt number were calculated changing volume fraction type nanoparticles tube. The effects Reynolds on studied. An exergy analytical model was established for laminar nanofluid under condition constant flow. At same condition, friction entropy production flow process tube increases with addition nanoparticles, decreases at time. However, magnitude is only 10?6, which negligible compared production. Therefore, general, loss lower than that pure water nanofluids, hybrid single fraction.

Measurement of Local Convective Heat Transfer Coefficient of Alumina-Water Nanofluids in a Double Tube Heat Exchanger

Heat transfer coefficient and thermal efficiency of γ-Al2O3/water nanofluids flowing through a double tube heat exchanger were experimentally investigated. The nanoparticles were well dispersed in distilled water at 0.05–0.15 %vol. A large number of experiments were performed at different fluid flow rates under turbulent flow regime (18,000<Re<40,000) and various nanofluid...

Numerical Comparison of Turbulent Heat Transfer and Flow Characteristics of SiO2/Water Nanofluid within Helically Corrugated Tubes and Plain Tube

Turbulent heat transfer in Helically Corrugated Tubes (HCT) was numerically investigated for pure water and SiO2 nanofluid using Computational Fluid Dynamics (CFD). This study was carried out for different corrugating pitches (5, 7, 8 mm) and heights (0.5, 0.75, 1.25 mm) at various Reynolds numbers ranging from 5000 to 13300. The effect of nanoparticles on heat transfer augmentation for plain t...

A numerical investigation of γ-Al2O3-water nanofluids heat transfer and pressure drop in a shell and tube heat exchanger

The effect of γ-Al2O3 nanoparticles on heat transfer rate, baffle spacing and pressure drop in the shell side of small shell and tube heat exchangers was investigated numerically under turbulent regime. γ-Al2O3-water nanofluids and pure water were used in the shell side and the tube side of heat exchangers, respectively. Since the properties of γ-Al2O3-water nanofluids were variable, they were ...
