Abstract

This paper gives the performance improvement of tractor radiator by
Cu/water nanofluid through the mechanism of nanotechnology. It was found that
the use of the nanofluid in heat transfer field can play a crucial role in
increasing the efficiency of equipment. Miniaturization and increased operating speeds of heat exchangers
warranted the need for new and innovative cooling concepts for better
performance. The nano materials and its suspension in fluids as particles have
been the subject of intensive study worldwide. Tractor Engine cooling is an
important factor for their performance
in the intended application. Here the tractor engine radiator cooling is
enhanced by nanofluid mechanism of heat transfer for its improved performance
in agricultural work. The experimental and numerical investigation for the
improved heat transfer characteristics of a radiator using Cu/water nanofluid
for 0.025, 0.05 and 0.075% volume fraction is done with inlet temp of 50 - 60°C under the turbulent flow
regime (8000 ≤ Re ≤ 25000). The overall heat transfer coefficient decreases
with increase in nanofluid inlet temperature of 50 - 60°C. The experimental results
when compared with numerical shows enhanced heat transfer coefficient. The results also
proved that nanofluid is better heat transfer fluid than the base fluid water. Experimental
results emphasize the enhancement of heat transfer due to the nanoparticles
presence in the fluid. Heat transfer coefficient increases by increasing the
concentration of nanoparticles in nanofluid. The nanofluids are projected as alternative cooling fluid in heat
exchangers through its nano mechanism. Further researches are required to study
the effect of nanotechnology to enhance the heat exchanger performance over the
next several coming years
