“…For a heat pipe heat exchanger with a constant wall heat flux condition, Motevasel et al 80 addressed by experiments the hydrothermal effects of three kinds of nanofluids (silicon carbide, copper oxide, and aluminum oxide at 0.0002 to 0.002 of concentrations in water). Compared with the base fluid, the selected concentrations yielded an increase in the heat transfer coefficient by about 11% to 18%.…”

Recently, many researchers have focused on their studies on the analysis of nanofluid flows due to their participation in the enhancement of heat transfer rates in industrial processes. The ordinary fluids, such as water, mineral oils, and so on, are known for their low thermal conductivity in heat transfer processes. A significant enhancement in the thermal properties of ordinary fluid may be obtained by adding nanoparticles having a diameter of less than 100 nm or suspension of fibers. Better spreading, wetting, dispersion, and stability and with acceptable viscosity are the main advantageous properties of nanofluids on a solid surface. The nanofluids are encountered in various thermal engineering systems such as in heat exchangers, refrigeration, thermal management of fuel cells, cooling of nuclear reactors, microelectromechanical systems, and others. In particular, the thermal conversion is known as a great application of nanotechnology, and many studies have been achieved with such fluids in heat exchangers. Therefore, this paper aims to present a global insight into the different applications of nanofluids in various heat exchangers, that is, heat pipe and plate-fin heat exchangers. All research works have been summarized into three main parts: laminar, transition, and turbulent nanofluid flow regimes.

“…In this work, the results he attained that the transition flow in the rectangular channel had 54% heat transfer enhancement compared to the turbulent flow with 11% at 1% concentration with the Reynolds number range of 200-7000. Mohsen Motevasel et al (13) observed that changes in the nanoparticle type had no significant effect on the increase in heat transfer coefficient. The heat transfer enhancement for Al2O3 nanofluid and aqueous surfactant solution was 140%, 207%, and 117% higher compared to pure water.…”

“…Sedong Kim et al (9) discussed that after Ultrasonic excitation over three different concentrated nanofluids created effective dispersion of nanoparticles in a base fluid compared to the untreated nanofluid which was kept for 7 days. Mohsen Motevasel et al (13) had used magnetic stirrer, ultrasonicator (UIP500, Hielsher Co.) and Zeta potential (Malvern, ZEN 3600) to measure the stability of the nanofluid which shows no sedimentation for 2 days and the Zeta potential value was more than 30 mV which denoted the nanofluid was stable. Modak et al (14) performed two-step method by preparing in Sonicator for 5 h continuously to acquire a more stable and evenly dispersed nano-particle suspension.…”

Heat exchangers are the most significant equipment used in the industrial sites for exchanging the useful energy for many applications. It may be used either for cooling or heating but in the industrial scenario, it mostly used for cooling. In the current research development, the nanoparticles of different high thermal conductivity metals have been prepared and introduced in the low thermal performance base fluids like water, oil, ethylene glycol to enhance its quality of heat absorption in the heat exchangers. In that alumina nanoparticle played a significant role in many research applications and it has good thermal conductivity as a pure fluid. So, in this review work, the recent study of Al2O3 nanofluid with its preparation method, thermo-physical properties and its performance in varied heat exchangers have been discussed. This would enrich the knowledge and help the researchers who are interested in alumina nanofluid for their experimental works.

Methods of computational fluid dynamics and design of experiments are implemented in modeling the heat transfer of an Al 2 O 3 /water-ethylene glycol (EG) nanofluid as a coolant in a car radiator system. The main purpose of the study is to propose a model to predict the Nusselt number using the design of computer experiment. The response surface methodology is applied to investigate the effects of the flow rate, the nanoparticle concentration, the water/EG ratio, and the inlet temperature on Nu. Analysis of variance is performed to obtain a suitable correlation that could predict Nu, leading to the elimination of insignificant terms in the initial proposed quadric model and the attainment of a reduced model. Moreover, the reduced model is converted to a simpler linear model using Box-Cox transformation, which predicts Nu with an accuracy of ±20 %.
