AB - In this present investigation, heat transfer performance of CeO2-ethylene  glycol as coolants in heat pipes are analyzed. Various concentrations of 0.5,  0.75, 1.0, 1.25, 1.5, and 2.0 vol.% with different volumetric flow 1.0, 2.0,  3.0, 3.5, and 4.0 lpm at a temperature of 40°C, are investigated  experimentally and the results are numerically analyzed by means of cross  tube heat exchanger and horizontal flow with twist plate insert. The results  are scrutinized to evaluate the best concentration which will reduce the size  of the existing radiator length. The results demonstrated that, for 0.75  vol.% combination of CeO2-ethylene glycol resulted in increase of heat  transfer coefficient compared to the combination of water-ethylene glycol.  Increase in volumetric flow rate of the coolant increase the heat transfer  coefficient results in the contraction of radiator length. Replacing the  original coolant with the proposed combination, it is estimated that the size  of the radiator, inventory of the fluid, and pumping power is reduced, thus,  making this nanofluid an energy efficient fluid for the engine cooling  system.
