520 |a The various debates in fluid dynamics from different critics made it so clear that the existence of nanoparticles in the fluids leads to raising the thermal conductivity of the fluid itself and therefore enhances the heat transfer properties. Moreover, the convection heat transfer behaviors that enhanced by nanoparticles in the fluids have been widely reviewed in mechanical engineering and modern industrial fields. Many researchers have studied the convection b undary layer flow of incompressible micropolar fluid. However, there is still a lack of studies that examine the behaviours of a micropolar nanofluid on a solid sphere and horizontal circular cylinder. In the present study, the free and mixed convection boundary layer flow for micropolar nanofluid on a solid sphere and horizontal circular cylinder has been considered. The governing dimensional equations of the boundary layer are first transformed into non-dimensional equations via non-dimensional variables. The non-dimensional equations are transformed into partial differential equations using similarity transformation. Next, the transformed nonlinear systems of equations are solved via an implicit finite difference scheme known as the Keller-Box method and programmed via MATLAB software. Effects of mixed convection, nanoparticle volume fraction and micropolar parameters on the behaviors of micropolar nanofluid are observed. The numerical result shows that a rise in nanoparticle volume fraction and rnicropolar parameters lead to increment in the local wall temperature and the temperature profile. Besides, the values of local wall temperature and temperature profile decrease when the values of mixed convection parameter increase. Furthermore, when the value of mixed convection parameter is positive, the behaviors of local skin friction, velocity, and angular velocity of the nanoparticles are opposite to the negative mixed convection parameter. The result concludes that the behaviors of micropolar nanofluid flow is significantly influenced by mixed convection, nanoparticle volume fraction and micropolar parameters. Therefore, this finding is expected to add a scientific insertion to the fluid mechanics field.
