The heat exchanger is an essential instrument in heat transfer. Various efforts have been carried out to improve heat transfer features. One of them is by adjusting the conventional cooling fluid using nanofluid. This study used MnFe 2 O 4 nanoparticle along with fluid obtained from a mixture of ethylene glycol (EG) and water. This research aims to identify heat transfer characteristics of a double pipe heat exchanger with MnFe 2 O 4 -EG/Water nanofluid using the CFD simulation method. The EG/Water mixture variation was 20, 40, 60, and 80% with MnFe 2 O 4 concentration of 0.05%. Besides, the nanofluid flow was also varied by 0.2; 0.4; and 0.6 l min −1 . The research results show that MnFe 2 O 4 nanofluid effects on heat transfer characteristics encounter an increase following the rise of MnFe 2 O 4 nanoparticle addition and higher water flow. In contrast, the addition of ethylene glycol carries a dreadful effect on this research. The improvement of heat transfer characteristic is hugely influenced by the increased thermal conductivity along with the addition of MnFe 2 O 4 nanoparticle.
