This research investigates the problem of stagnation point flow and heat transfer over a
stretching/shrinking sheet past a porous medium with suction effect. Firstly, the
mathematical model that governed the fluid flow and heat transfer were formulated. Then,
the governing nonlinear partial differential equations were transformed into ordinary
differential equations using similarity transformation. The system of ordinary differential
equations is then solved numerically using bvp4c function in Matlab software. The effect of
suction on the skin friction coefficient and the local Nusselt number, as well as the velocity
and temperature profiles, are obtained and analysed. The numerical result obtained is
presented in the form of graphs and tables. The dual solutions are obtained for a certain
range of parameters. The stability analysis has been performed and the result shows that
the upper branch solution is stable while the lower branch solution is unstable
