Abstract

In this paper, for the first time, the application of nanofluids is investigated from the Thermo-Economic point of view. For this purpose, the mixed convection flow of Al2O3-EG nanofluid in an isothermal vertical annulusis considered where three sets of models are used to calculate the viscosity and thermal conductivity of nanofluid.The main aim of this work is to estimate of operational costs ($) due to entropy generation using nanofluids in the annulus. The results show that using nanofluids is not cost effective in short periods (i.e. 5-6 months) from the second law of thermodynamics point of view. In future works, besides the entropy generation, changes in heat transfer rate that occurs using nanofluids and their effects on the costs can be considered.
