Abstract

We are interested in study of the velocity (𝑓′) and temperature (πœƒ) profiles for fluid flow over the surface of porous flat plate with the effect of magnetohydrodynamics. The dimensional equations are first transformed into the non-dimensional equations. Then, we transform the non-dimensional equations into the similar equations using stream functions. The numerical results are based on the discretization of similar equations using the finite difference method of Keller-Box. Based on the numerical results, the velocity profiles (𝑓′) decrease when the viscoelastic parameter (𝐾), Prandtl number (π‘ƒπ‘Ÿ), magnetic parameter (𝑀), porosity parameter (𝑃) are increased. Moreover, the temperature profile (πœƒ) is increased when the viscoelastic parameter (𝐾) and magnetic parameter (𝑀) are increased. However, the temperature profile (πœƒ) decreases when Prandtl number (π‘ƒπ‘Ÿ) and porosity (𝑃) are increased.
