Abstract
In this paper, we investigate the boundary layer flow near the stagnation-point region over an exponentially stretching/shrinking sheet with suction and velocity slip in a porous medium. The governing equations are first reduced to the ordinary differential equations with the help of similarity transformations. The obtained equations are then solved numerically using the bvp4c programme in MATLAB. It is observed that the ordinary differential equations have dual (first and second) solutions. The analysis of the results obtained reveals that as the porosity, suction and velocity slip parameters increase, the range in regards to the region of existence of dual solutions increases as well. Stability analysis is performed to determine the stability of the dual solutions obtained. The results indicate that the first solution is stable while the second solution is unstable.
