Analysis of working nanofluids for a refrigeration system

This paper presents the analysis of nanorefrigerant fluids to improve the thermal efficiency of a refrigeration system. Simulations in ANSYS FLUENT 15.0 were performed with mixtures of refrigerants R113, R123 and R134a, with Al2O3 nanoparticles at 1 vf% and 5 vf% (vf%, fraction volume concentration)...
