Newtonian heating effects on Magneto micropolar f luid flow on vertical porous plate

In this paper, a study on the magneto hydrodynamic (MHD) incompressible micropolar fluid flow, considering the effects of Lorentz force, Joule heating and Newtonian heating on an impermeable porous vertical sheet with slip condition and heat generation has been carried out. Governing equations is solved numerically using Runge-Kutta Fehlberg fourth fifth method after the transformation of PDE into ODE. The main goal of this paper is to investigate the effects of changes in the values of material parameter (K), buoyancy parameter (  ), Hartman number (Ha), Prandtl number (Pr), Eckert number (Ec), heat generation parameter (Q), suction ( 0 f  0 ) and injection ( 0 f  0 ) parameters, the slip flow parameter ( ), Newtonian heating parameter (  ), and (n) parameter on linear velocity, angular velocity and temperature profiles, and also investigation of the effect of these parameters and dimensionless numbers on the skin friction coefficient, wall couple stress, and local Nusselt number which obtained results are presented in tables and charts.
