| description | In this paper, the problem of unsteady magnetohydrodynamic (MHD) viscoelastic fluid
flowing towards a stagnation point on a vertical surface is studied. The temperature of the
surface is assumed to vary linearly with the distance from the stagnation point. The partial
differential equations which governed the flow are transformed into a system of ordinary
differential equations, which are then solved numerically by an implicit finite-difference
scheme known as the Keller-box method. The effects of the viscoelastic parameter K, mixed
convection parameter λ, magnetic parameter M and Prandtl number Pr on the flow and heat
transfer characteristics are presented in this paper. The numerical solutions obtained are
uniformly valid for all dimensionless time from initial unsteady-state flow to final steady-state
flow in the whole spatial region |
