Abstract
This research aims to demonstrate the change of thermal properties, temperature and thermal conductivity, which presents a base fluid (water) by adding a certain percentage of nanoparticles (CuO) and how they increase modify these properties in the processes that involve the heat transfer. For this reason, a study of the properties of the water-based CuO nanofluid at a concentration of 0.3% was carried out and a comparative analysis on heat transfer with water fluid without nanoparticles was developed with a CDF simulation software. According to the results obtained, the temperature difference in the base fluid and the nanofluid is 27.5 and 68.7 ° C respectively, which shows a significant improvement in energy transfer, the peak heat flow in the wall of the exchanger using the nanofluid is approximately ten times greater than the base fluid with values of 5394020 and 549765 (W m-2) respectively. There is also a considerable improvement in terms of thermal conductivity because its peak value in the nanofluid is 1825,825 times greater than the peak value of the base fluid.
