The system of coupled partial differential equations was first transformed into a system of coupled ordinary differential equations using the method of similarity transformation, which was then solved using the classical fourth order Runge-Kutta formula together with the shooting techniques. The effects of the thermo-physical parameters were then investigated. The Nusselt number is also determined numerically and compared with the case of flow over a flat plate, It is discovered that the plane stagnation point flow has higher Nusselt numbers due to the presence of the pressure gradient.

The laminar flow of viscous incompressible and electrically conducting fluid encompassing a convectively heated stationary permeable sheet is assumed to be described in terms of Darcian law. The nonlinear governing partial differential equations obtained are converted into ordinary differential equations by means of appropriate similarity transformations and consequently solved numerically using the forth order Runge-Kutta method with a shooting technique and depicted graphically for some pertinent values of the physical parameters embedded in the flow model. In addition, the skin-friction coefficient, the heat and pollution mass concentration rates are sorted out in tabular form, analyzed and discussed. We opine that findings of this present study will be found useful for environmental systems in pollution control and ventilation, and serve as complementary reference for researchers.

steady two dimensional , incompressible , viscous electrically conducting, chemically reacting laminar fluid
over a vertical convectively heated , electrically neutral flat plate exposed to a transverse uniform magnetic
field has been carried out to examine the influence of the simultaneous presence of the effects of a convective
boundary condition, chemical reaction, heat transfer and suction or injection. The governing coupled partial
differential equations have been reduced to a set of coupled nonlinear ordinary differential equations by means
of the similarity transformation , which has been solved using the classical fourth order Runge-Kutta method
alongside with a shooting technique. The computational results have been presented by means of the table and
discussed graphically. It has been observed that pertinent and invaluable engineering parameters such as the
Skin-friction coefficient, the plate temperature distribution, the velocity , temperature and concentration profiles
are appreciably influenced by flow parameters such as the magnetic field, convective heat parameters , Prandtl

boundary conditions. The mathematical model is presented for a two-dimensional steady, incompressible,
electrically conducting and laminar free convection boundary layer flow over a vertical plate in a chemically
reacting medium with an applied transverse magnetic field to the direction of flow. The basic partial differential
equations are transformed and reduced to a system of non-linear ordinary differential equations by the use of
the similarity transformation. The problem is addressed numerically, using fourth-order Runge-Kutta iterative
scheme together with a shooting technique. It is observed that the velocity, temperature and concentration
profiles are appreciably influenced by the presence of the transverse magnetic fields. We also discussed,
graphically, the effects of the various hydromagnetic, heat and mass transfer parameters involved in the
governing equations on the Skin-Friction coefficient, Nusselt and Sherwood numbers.

conditions in the presence of a uniform magnetic field. The system of coupled partial differential equations
obtained from the modelled fluid flow was first transformed into a system of coupled ordinary differential
equations with the use of similarity transformation. The ordinary differential equations are solved using fourth
order Runge-Kutta formula together with shooting technique. The features of the flow and heat transfer
characteristics for different values of the relevant flow quantities in engineering are investigated. Under this
study, the Nusselt number and skin friction coefficient are obtained numerically and the results compared with
those in the literature. It is seen that the magnetic field has a significant influence on the skin friction as the skin
friction decreases with increasing values of the magnetic parameter whereas the combined influence of
pressure gradient and magnetic fields invokes minimal changes on the Nusselt number .
