“…Liquid flow rate to radiator has been varied between 2 to 5 lit/min and the temperature was kept in the range of 37 to 49°C. They observed an increase in heat transfer rate with the presence of Al 2 An extensive review on water/ethylene glycol based nanofluids and their applications have been done by Azmiet al [3]. The authors concluded that many investigations on nanofluids with different types of nanomaterials and based fluids have shown that nanofluids possess better thermal performance.…”

Abstract:The use of nanoparticle dispersed coolants in automobile radiators improves the heat transfer rate and facilitates overall reduction in size of the radiators. In this study, the heat transfer characteristics of water/propylene glycol based TiO 2 nanofluid was analyzed experimentally and compared with pure water and water/propylene glycol mixture. Two different concentrations of nanofluids were prepared by adding 0.1 vol. % and 0.3 vol. % of TiO 2 nanoparticles into water/propylene glycol mixture (70:30). The experiments were conducted by varying the coolant flow rate between 3 to 6 lit/min for various coolant temperatures (50°C, 60°C, 70°C, and 80°C) to understand the effect of coolant flow rate on heat transfer. The results showed that the Nusselt number of the nanofluid coolant increases with increase in flow rate. At low inlet coolant temperature the water/propylene glycol mixture showed higher heat transfer rate when compared with nanofluid coolant. However at higher operating temperature and higher coolant flow rate, 0.3 vol. % of TiO 2 nanofluid enhances the heat transfer rate by 8.5% when compared to base fluids.

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.

“…For instance, Leong et al [19] reported the heat transfer enhancement of an automotive car radiator using ethylene glycol with 2% copper as nanofluid (with ethylene glycol as the base fluid for comparison); they observed that the overall heat transfer coefficient and bulk heat transfer increased by about 3.8% with the use of the nanofluid compared to the base fluid alone. The work of Peyghambarzadeh et al [20] tested five different concentrations for nanofluid of alumina nanoparticles in water in the range of 0.1 to 1% volume, as they compare to pure water in an automobile radiator. Their results demonstrated that the nanofluids with those low concentrations can enhance heat transfer efficiency up to 45% in comparison to pure water.…”

Nanofluids are nanosize-powder suspensions that are of interest for their enhanced thermal transport properties. They are studied as promising alternatives to ordinary cooling fluids, but the tribiological effects of nanofluids on cooling-system materials are largely unknown. The authors have developed methodology that uses jet impingement on typical cooling-system materials to test such effects. The work is presented of the authors' research on the interactions of a typical nanofluid (2% volume of alumina nanopowders in a solution of ethylene glycol in water) which is impinged on aluminum and copper specimens for tests as long as 112 hours. The surface changes were assessed by roughness measurements and optical-microscope studies. Comparative roughness indicate that both the reference cooling fluid of ethylene glycol and water and its nanofluid with 2% alumina produce roughness changes in aluminum (even for the shortest 3-hour test), but no significant roughness differences were observed between them. No significant roughness changes were observed for copper. Microscopy observations, however, show different surface modifications in both aluminum and copper by both the nanofluid and its base fluid. The possible mechanisms of early erosion are discussed. These investigations demonstrate suitable methods for the testing of nanofluid effects on cooling system-materials.
