Abstract

The analytical efficacy method (ε-NTU) is applied to analyze the thermal performance of the radiator with Multi-Louvered flat-tube fins. The nanofluid is composed of a suspension of silver nanoparticles in ethylene glycol. The rate of heat transfer, efficiency, and outlet temperatures of the nanofluid and air are determined and presented in graphical form. The volumetric fraction of the nanoparticles suspended in ethylene glycol, the variations in the airflow rate and the nanofluid flow rate is the main parameters used in the analysis. The analysis showed promising results since it is possible to save on the use of the compact heat exchanger considered, reducing costs and storage space for the refrigerant.
