MHD Newtonian and non-Newtonian Nano Fluid Flow Passing On A Magnetic Sphere with Mixed Convection Effect

This paper considers the problem of magneto-hydrodynamics (MHD) Newtonian and non-Newtonian nano fluid flow passing on a magnetic sphere with mixed convection effect. Nano Fluid is a combination of liquid fluid as a base fluid with small solid nano particles. Water is chosen as Newtonian base fluid and oil is chosen as nonNewtonian base fluid. Then, Alumina and Copper are chosen as solid particle in nano fluid. We further construct governing equation by applying continuity equation, momentum equation, and energy equation to obtain dimensional governing equations. The dimensional governing equations that have been obtained are converted into non-dimensional governing equations by substituting non-dimensional variables. The non-dimensional governing equations are further transformed into similarity equations using stream function and solved numerically using Euler Implicit Finite Difference method. We further analyse the effect of magnetic parameter towards velocity and temperature in MHD nano fluid flow. The results show that the increases of magnetic parameter impacts to the decrease of velocity and temperature. Then, the velocity and temperature of Newtonian nano fluid are higher than the velocity and temperature of non-Newtonian nano fluid. Also, the velocity and temperature of copper-water are higher than the velocity and temperature of Alumina-water.
