Abstract: Slip effects on steady laminar hydromagnetic flow of a viscous, electrically conducting and radiating fluid over a porous nonlinear stretching surface in the presence of non-uniform internal heat generation, viscous and Ohmic dissipation has been investigated. The governing nonlinear partial differential equations of momentum and energy are reduced to nonlinear ordinary differential equations by suitable similarity transformation. The resulting nonlinear ordinary differential equations are solved numerically utilizing Nachtsheim Swigert shooting iteration technique for satisfaction of asymptotic boundary conditions along with Runge-Kutta fourth order integration scheme. Effects of various governing physical parameters on velocity and temperature distributions as well as on the skin friction coefficient and Nusselt number are presented through graphs and tables and they are discussed. The individual effect of velocity slip parameter, magnetic field, power-law index parameter and suction has the same influence over the velocity so as to decelerate it. It is noted that velocity slip, non-uniform internal heat generation parameter and Eckert number enhance the temperature whereas the thermal slip parameter and radiation parameter reduce the temperature distribution. Comparative study with the available published results for particular cases shows an excellent agreement. |
Keywords and phrases: MHD, radiation, slip, non-uniform internal heat generation.
