Analysis of Unsteady Magneto Hydro Dynamic (MHD) Nano Fluid Flow Past A Sliced Sphere

Abstract

A mixture of among solid small size nanoparticles with liquid fluid as the basic fluid, called nano fluid. Size of nano fluid partical 1-100 nm. Magnetohydrodynamic (MHD) is the movement of a fluid flow which is affected by a magnetic field, has high efficiency. The research discussed, analysis unsteady magnetohydrodynamics (MHD) at nano fluid boundary layer that past sliced sphere. The research will search how to form Dimensional governing equations. Nano fluid flow is influenced by the magnetic field cause the boundary layer until formed Non-similar equations boundary layer and then solved numerically using finite difference method with Keller-Box scheme. In this reasearch will show to influence the variations in non dimensional nano fluid density parameters (ρND), nano fluid heat capacity non dimensional variations (ρCND), and nano particle volume fraction variations (χ) to velocity profile (f′) and temperature profile (s). The results of the research, if the variation of non dimensional nano fluid density(ρND) is greater then the velocity profile increases but the temperature profile decreases, the greater variation in value of non-dimensional nano fluid heat capacity (ρCND) the velocity profile will increase constantly but the temperature profile increases significantly, the greater temperature the velocity profile variation of nanoparticle volume fraction (χ) increases when the value is 0 ≤ χ ≤ 0.5 and decreases at the value is 0.6 ≤ χ ≤ 0.9, the greater nanoparticle volume fraction (χ) variation the temperature profile increases.
