Abstract

The convective heat transfer and
entropy generation characteristics of Ag-MgO/water hybrid nanofluid flow
through rectangular minichannel were numerically investigated. The Reynolds
number was in the range of 200 to 2000 and different nanoparticle volume fractions
were varied between



















= 0.005 and 0.02. In addition, Artificial
Neural Network was used to create a model for estimating of entropy generation
of Ag-MgO/water hybrid nanofluid flow. As a result, it was found that the
convective heat transfer coefficient for

= 0.02 Ag-MgO/water hybrid nanofluid is
21.29% higher than that of pure water, at Re=2000. Total entropy generation of
Ag-MgO/water hybrid nanofluid increased with increasing nanoparticle volume fraction.
The results obtained by ANN showed good agreement with the numerical results
obtained in this study.
