“…In view of the potential use of nanouids in heat exchange processes [11,12] in the industry, the theoretical * corresponding author; e-mail: gzyla@prz.edu.pl model of mechanical properties of these materials would be extremely valuable. Unfortunately, there is no coherent theoretical model invented at the moment, describing the rheological behavior of nanouids.…”

The paper presents the results of measurements of rheological properties of ethylene glycol (EG) based aluminum oxide (Al2O3) nanouids. The nanouids have been produced by two-step method with the use of commercially available nanoparticles. Dynamic viscosity curves and dependence of viscosity on temperature for these materials have been measured. It has shown that with higher concentration of nanoparticles in the suspension, these nanouids exhibit the non-Newtonian ow and it can be considered as shear-thinning liquids. The eect of temperature on the dynamic viscosity in Al2O3EG nanouids can be modelled with the use of VogelFulcher Tammann expression.

“…Cylindrical shaped nanoparticle showed better performance in terms of thermal conductivity, heat transfer coefficients, and heat transfer rate. Albadr et al [8] conducted an experimental and numerical study on a heat transfer through the heat exchanger using Al 2 O 3 nanofluid at different concentrations. In this study, the convective heat transfer performance and flow characteristics of Al 2 O 3 nanofluid flowing in a horizontal shell and tube heat exchanger have been experimentally investigated.…”

“…Albadr et al [21] conducted several experiments using different concentrations of Al2O3 nanofluid to see its effect on the heat transfer of a heat exchanger. It is perceived that the heat transfer coefficient is higher with nanofluids rather than 100% water.…”

This paper presents the effect of number of tubes, unequal baffle spacing and tube diameter on heat transfer and pressure drop characteristics of a typical shell and tube type heat exchanger. Upon geometrical optimization, the second phase of this research work aims at studying the influence of Al2O3 nanofluid of 0.5%, 0.75%, 1%, 1.25% and 1.5% concentrations by admitting water along the tubes and Al2O3 nanofluid along the shell side. The shell and tube heat exchangers of various geometrical configurations are modeled using SOLIDWORKS 2015. The heat transfer and fluid flow characteristics through the heat exchanger are obtained by solving the governing equations namely continuity, momentum and energy equations using ANSYS CFX 15 CFD code. Temperature, pressure contours and velocity streamlines along the mid-plane of the shell and tube heat exchanger are obtained for various geometrical configurations and for different volume concentration of nanofluid. The heat transfer coefficient and the pressure drop for various volume fraction concentrations of the nanofluid are plotted. The use of nanofluid resulted in increase of both the pressure drop and heat transfer coefficient. The heat transfer coefficient at 1.25% volume concentration of nanofluid is found to be the optimum value.
