## Abstract

Unsteady two-dimensional stagnation point flow of an incompressible viscous fluid over a flat deformable sheet is studied when the flow is started impulsively from rest and the sheet is suddenly stretched in its own plane with a velocity proportional to the distance from the stagnation point. After a similarity transformation, the unsteady boundary layer equation is solved numerically using the Keller-box method for the whole transient from Ï„=0 to the steady state Ï„â†’âˆž. Also, a complete analysis is made of the governing equation at Ï„=0, the initial unsteady flow, at large times Ï„=âˆž, the steady state flow, and a series solution valid at small times Ï„ (1). It is found that there is a smooth transition from the initial unsteady state flow (small time solution) to the final steady state flow (large time solution
