“…Due to the high heat transfer characteristics of nanofluids, the engine wall temperature and the in-cylinder temperature was further reduced. The enhancement of heat transfer characteristics of CuO/water nanofluids as claimed by previous research works [25,26]. From the literature reviews, the heat transfer coefficient of CuO/water nanofluids is the function of % volume concentrations and flow rates.…”

This article reports the effects of CuO/water based coolant on specific fuel consumption and exhaust emissions of four stroke single cylinder diesel engine. The CuO nanoparticles of 27 nm were used to prepare the nanofluid-based engine coolant. Three different volume concentrations (i.e 0.05%, 0.1%, and 0.2%) of CuO/water nanofluids were prepared by using two-step method. The purpose of this study is to investigate the exhaust emissions (NO x ), exhaust gas temperature and specific fuel consumption under different load conditions with CuO/water nanofluid. After a series of experiments, it was observed that the CuO/water nanofluids, even at low volume concentrations, have a significant influence on exhaust emissions. The experimental results revealed that, at full load condition, the specific fuel consumption was reduced by 8.6%, 15.1% and 21.1% for the addition of 0.05%, 0.1% and 0.2% CuO nanoparticles with water, respectively. Also, the emission tests were concluded that 881 ppm, 853 ppm and 833 ppm of NO x emissions were observed at high load with 0.05%, 0.1% and 0.2% volume concentrations of CuO/water nanofluids, respectively.

“…In another study [17] have used different base fluids including ethylene glycol and their binary mixtures with Al2O3 nanoparticles and once again it has proved that Nano fluids improve the cooling performance of an automobile radiator extensively. [15] found that thermal conductivity of CuO/water Nano fluids was much higher than that of base fluid water. He found that the overall heat transfer coefficient increases with the enhancement in the Nano fluid concentration from 0 to 0.4 vol %.…”

“…Convective heat transfer coefficient along the flat tubes with the Nano fluid flow showed considerable improvement over the base fluid. [15] have recently investigated the application of Al2O3 /water Nano fluids in the automobile radiator by calculating the tube side heat transfer coefficient. They have recorded the interesting enhancement of 45% comparing with the pure water application under highly turbulent flow condition.…”

Abstract-In this paper, results of experiment carried out on an automotive radiator with water and water based Al 2 O 3 nanofluids are compared. The experimentation is done by considering variable parameters so as to study the effect of flow rate, inlet temp of coolant and volume fraction of nanofluids on thermal performance of automotive radiator. 13nm sized Al 2 O 3 particle are dispersed in water with 0.5-2.5vol% with twostep method. These fluids are made to flow through a radiator with flow rate of 6-8lpm to have fully turbulent regime. Also the effect of fluid inlet temperature to radiator on heat transfer performance been analyzed by keeping the temperature at 60°C. Results showed improved heat transfer performance with increasing fluid circulation rate. The presence of 13nm sized alumina nanoparticles in water enhances the heat transfer rate of the automobile radiator. At the concentration of 2 vol% the heat transfer enhancement of 38% compared to pure water was recorded.
