Description
Summary:In this paper, the heat transfer flow of a micropolar nanofluid mixture containing three types of oxide nanoparticles namely titanium oxide (TiO2), alumina oxide (Al2O3) and graphene oxide (GO) which suspended in two different types of fluids such as water and kerosene oil are investigated over a heated horizontal circular cylinder with constant surface heat flux. The dimensionless form of governing equations are solved via an implicit finite difference scheme known as Keller-box method. The effects of nanoparticles volume fraction, Prandtl number, micro-rotation parameter on temperature, velocity and angular velocity are plotted and discussed. Further, numerical results for the local wall temperature and the local skin friction coefficient are obtained. It is found that the local wall temperature of Al2O3 based nanofluid is higher than the other oxide based nanofluid, but the local skin friction of GO is higher than the other oxide nanoparticles, for every values of nanoparticle volume fraction and micro-rotation parameter. The present results of local wall temperature and local skin friction for Newtonian fluid are found to be in good agreement with the literature.
