Unsteady stagnation point flow and heat transfer over a stretching or shrinking sheet

The study is focused on investigating the effects of unsteady stagnation point ow and heat transfer over a stretching/shrinking sheet. The problem is modeled as a mathematical formulation that involves a system of partial differential equations. The governing partial differential equations are then...
