Resumen

This article aims to contribute to an improvement in the heat transfer of hydrocarbon refrigerants due to the great need to replace HFC refrigerants, which have generated significant damage to the ozone layer, so it was carried out a numerical comparison for the parameter of thermal conductivity in the isobutane R600a adding two different nanoparticles in order to know the parameters of these mixtures that present an improvement in their operation, for this it has been required of the commercial simulation software ANSYS fluid since In this are the models of energy, discrete phase, injection and turbulence to find the results. In the development of the simulation a volumetric fraction of nanoparticles was determined up to 5%. The conditions of the base fluid and the nanoparticles are described in the document. The simulation showed that for the conditions given, the R600a/Al2O3 nanorefrigerant has a better thermal conductivity, compared to the R600a/CuO and the base refrigerant.
