“…(Nasiri et al, 2011) presented the experimental results for Al2O3/water nanofluid with concentrations of 0.5% and 1% at Peclet number about 59,000 under turbulent regime in annular circular tube and showed the increments of Nusselt number were 6.2 % and 13.6% respectively. The corresponding results, for the present study, at the same Peclet number and nanoparticle concentrations are 1.1%, 2.3%.…”

“…It is worth mentioning that the nanoparticles deposition is not observed until the nanofluid becomes stagnant or quasi-stagnant (with low speed). As the nanofluid passes through the pump, it undergoes high shear and stress tensions; thus clustering is removed (Nasiri et al, 2011). Additionally, high flow rate in the radiator tubes and connecting pipes improves the stabilization of the nanofluid.…”

In this experimental study, heat transfer of a coolant nanofluid, obtained by adding alumina nanoparticles to Ethylene Glycol-water (60:40 by mass), in a car radiator has been investigated. For this purpose, an experimental setup has been designed and constructed. Firstly, to investigate the accuracy of the results, the experiments have been done for the base fluid. Then the experiments have been performed for the nanofluid with different nanoparticles volume fractions of 0.003, 0.006, 0.009 and 0.012. To ensure laminar flow regime three coolant flow rates of 9, 11 and 13 lit/min have been tested. The thermophysical properties have been calculated using the recently presented temperature dependent models in the literature. According to the results, both the convective heat transfer coefficient and Nusselt number increase (about 9%) with increasing the coolant flow rate. Also, convective heat transfer coefficient increases with increasing the nanoparticles volume fraction. Although Nusselt number decreases when nanofluid is utilized, it enhances as the nanoparticles volume fraction increases. Based on the experimental results obtained, A new empirical correlation has been developed for average Nusselt number of Al2O3-EG-water nanofluid in developing region of flat tubes of car radiator for laminar flow and its maximum error is 3%.

“…Fotukian and Esfahany [26] reported significant improvement of heat transfer and studied the pressure drop of CuO-water nanofluid through a circular tube for a range of Reynolds number of 5,000-33,000. Nasiri et al [27] found enhancement of heat transfer with Al2O3 and TiO2 nanoparticles dispersed into water through an annular duct under constant wall temperature for a range of Reynolds number 4,000 to 12,000 and volume fraction 0.1% to 1.5%. Heyhat et al [28] conducted experiments to observe the enhancement of heat transfer and pressure drop of Al2O3-water nanofluid in a circular tube under constant wall temperature for both laminar and turbulent flow condition.…”

The implementation of nanofluid within a preferred volume fraction in base fluid is one of the innovative and inexpensive methods of enhancing the thermal and hydrodynamic behaviour in terms of increased heat transfer rate and reduced pumping power. In the present paper, forced convection heat transfer and pumping power were studied for a rough parallel plate subjected to constant heat flux under turbulent flow condition. The investigation was performed for a wide range of Reynolds number 10,000 to 30,000 with Al2O3 nanoparticles volume fraction 1% to 5% dispersed in base fluid water and three different rough surfaces (relative roughness: 0.001, 0.002, and 0.003) were considered. Heat transfer performance was substantially improved more by employing roughness at the wall of the boundary than the smooth parallel plate and also for the increased more volume fraction of nanofluid than base fluid water. Augmentation was found significant at higher surface roughness and volume fraction by the virtue of superior thermo-physical properties of nanofluid up to 36.9% and 26.1% for the rough surface. Roughness did not increase the pumping power as its effect was mitigated by the nanofluid. 2% volume fraction of Al2O3-water nanofluid on 0.003 relative roughness that showed the superior behaviour for heat transfer enhancement with minimum pumping power requirement.
