Abstract
In this work we address the rotating flow of nanofluids induced by an exponentially stretching sheet. Five different types of nanoparticles namely Silver-Ag, Copper-Cu, Copper oxide-CuO, Titanium oxide-TiO2 and Aluminum oxide-Al2O3 are considered. Convective boundary conditions are implemented to inspect the thermal boundary layer. The arising differential system is treated through a numerical approach. Analysis is based on two different models for effective thermal conductivity of nanofluids. The results reveal that the effects of parameters appear to be qualitatively similar in both the considered models. We found that thermal boundary layer thickness increases and heat transfer rate decreases upon increasing the angular velocity of the rotating fluid. The results indicate that convective heat transfer of Al2O3-water nanofluid is superior to the other used nanoparticles.
