Experimental Investigation of Heat Transfer Performance of Different Nanofluids Using Automobile Radiator

Abstract

TIn this present study, the forced convection heat transfer performance of different fluids, namely, Al2O3-water, and CuO-water nanofluid has been studied experimentally in an automobile radiator. Three different concentration of nanofluid in the range of 0-1.0 vol.% have been prepared by addition of Al2O3and CuO nanoparticles into water. The test fluid flow rate can be varied in the range of 2 l/min to 5 l/min to have a fully turbulent regime. Obtained results demonstrate that the fluid circulating rate can improve the heat transfer performance. The heat transfer performance of CuO-water nanofluid was found better than the other heat transfer fluids. Furthermore, the Nusselt number is found to increase with the increase in the nanoparticle concentration and nanofluid velocity.

Enhancing automotive cooling systems: composite fins and nanoparticles analysis in radiators

“…Senthilraja et al 17 conducted a study on the effects of temperature on radiator pipes and cooling techniques using computational fluid dynamics (CFD). While their investigation was primarily based on normal water fluids, they also explored the use of Nano fluids made from aluminum oxide and titanium oxide.…”

Comparative molecular dynamics simulations of thermal conductivities of aqueous and hydrocarbon nanofluids

“…In a similar aspect, it was also found that hybridized nanoparticles considerably improve the conductive properties of base fluids. Raja et al [ 34 ] carried out an experiment in which a comparative study of the thermal behaviour of normal and hybrid nanofluids (Al 2 O 3 /H 2 O, CuO/H 2 O and Al 2 O 3 –CuO/H 2 O) was observed. Hybrid nanofluids (Al 2 O 3 –CuO/H 2 O) showed greater enhancement in thermal properties than other conventional nanofluids (CuO/H 2 O, Al 2 O 3 /H 2 O).…”
