An analysis has been carried out to obtain the nonlinear MHD flow with heat transfer characteristics of an incompressible, viscous and Boussinesq fluid on a vertical stretching surface with power-Iaw velocity. An approximate numerical solution for the flow problem has been obtained by solving the goveming equations using a numerical technique. A magnetic field is applied transversely to the direction of the flow. Adopting the similarity transformation, goveming nonlinear partial differential equations of the problem are transformed to nonlinear ordinary differential equations. Then the numerical solution of the problem is drawn using the Runge Kutta Gili method. NumericaI caIculations are carried out for different values of the dimensionless parameters in !he problem and an analysis of the results obtained show that the flow field is influenced appreciably by the presence of the magnetic field and thermal stratification effect.

An analysis is carried out to study a nonlinear hydromagnetic flow, heat and mass transfer over an accelerating vertical surface with internal heat generation and chemical reaction. The fluid is assumed to be incompressible, viscous, electrically conducting and Boussinesq. A magnetic field is applied transversely to the direction of the flow. The similarity transformation has been utilized to convert the governing partial differential equations into ordinary differential equations and then the numerical solution of the problem is drawn using Runge Kutta Gill method. Numerical calculations for different values of dimensionless parameters entering the problem under consideration are carried out for the purpose of illustrating the results graphically. Examinations of such flow models reveal the influence of the chemical reaction, Prandtl number and strength of the magnetic field.

The problem concerns a nonlinear laminar boundary layer, chemical reaction, heat and mass transfer flow of an incompressible and viscous fluid past a continuously moving infinite vertical porous plate in the presence of suction under the influence of heat source and thermal diffusion. The similarity transformation has been utilized to convert the governing nonlinear partial differential equations into nonlinear ordinary differential equations and then the numerical solution to the problem is given using the Gill method. The analysis of this results obtained shows that the flow field is influenced appreciably by the presence of suction at the surface, chemical reaction and magnetic effects.
