Análisis y simulación mediante fluent de ANSYS del proceso de evaporación de la mezcla de refrigerante 600a y nanopartículas de óxido de cobre en un intercambiador de calor tipo tubo recto

Abstract

The purpose of this study is to analytically and numerically compare the convective heat transfer coefficient that exists between pure R600a, R600a / CuO up to 5% volumetric fraction and straight tube heat exchanger; and at the same time corroborate that the thermal transport properties for the nanorefrigerant improve compared to those of the pure R600a. Through a quantitative research method through scientific articles and books, the thermophysical properties and the analytical formulas of the thermal transport properties were determined both for the pure coolant and for the mixture of R600a and copper oxide nanoparticles, achieving determine through the calculations made the improvement of the properties of the R600a / CuO at 5% volumetric fraction. For the numerical simulation using ANSYS fluent models were chosen according to the type of simulation performed, the results obtained by varying the speed of flow input and the concentration of nanoparticles between 1% and 5% determine that the evaporation process It is easier to carry out, as well as reaffirm that the properties of the mixture are much better compared to those of R600a in its pure state.
