The influence of heat generation or absorption on the steady, two-dimensional flow
of an electrically conducting fluid near a stagnation point on a stretching permeable
surface with variable surface heat flux in the presence of a magnetic field is investigated.
The governing system of partial differential equations describing the problem
are converted into highly non-linear ordinary differential equations using similarity
transformation. Numerical solutions of these equations are obtained using the
fourth-order Runge-Kutta integration scheme with the shooting method. The effects
of the heat generation or absorption parameter and the velocity ratio parameter on
the velocity and the temperature are displayed graphically and discussed. The
numerical values of the local skin-friction coefficient and the local Nusselt number
for various values of physical parameters are presented through tables and discussed. |
