چکیده
|
This study is devoted to investigate the radiation, heat generation viscous dissipation and magnetohydrodynamic effects on the laminar boundary layer about a flat-plate in a uniform stream of fluid (blasius flow), and about a moving plate in a quiescent ambient fluid (sakiadis flow) both under a convective surface boundary condition. using a similarity variable, the governing nonlinear partial differential equations have been transformed into a set of coupled nonlinear ordinary differential equations, which are solved numerically by using shooting technique alongside with the forth order of runge-kutta method and the variations of dimensionless surface temperature and fluid-solid interface characteristics for different values of magnetic field parameter m, grashof number gr, prandtl number pr, radiation parameter nr, heat generation parameter q, convective parameter y and the eckert number ec, which characterizes our convection processes are graphed and tabulated. quite different and interesting behaviors were encountered for blasius flow compared with a sakiadis flow. a comparison with previously published results on special cases of the problem shows excellent agreement.
