dc.description.abstract	Abstract. This study aims to determine the effect of temperature and volume fraction on heat transfer rate and heat transfer coefficient on concentric tube heat exhanger with nano ethylene glycol / TiO2 fluid. From the results of tests and analyzes that have been done, it is obtained the best temperature and volume fraction that supports the rate of heat transfer. The best heat transfer rate of 22,430.25 W is done at the condition of the 0.03% TiO2 Volume Fraction and at a temperature of 100 ° C. The best heat transfer coefficient occurs at a volume fraction of 0.03% and at a temperature of 100 ° C. It can be concluded that, TiO2 will increase the heat capacity and heat conductivity of the base fluid which will optimize the performance of the fluid.
