Stagnation-point flow over a nonlinearly stretching/shrinking sheet in a micropolar fluid

The problem of a steady stagnation-point flow towards a nonlinearly stretching/shrinking sheet immersed in an incompressible micropolar fluid is studied. The governing partial differential equations are transformed into a system of nonlinear ordinary differential equations using a similarity transformation, before being solved numerically by a shooting method. The results show that increasing the material parameter K is to increase the skin friction coefficient (in absolute sense). Moreover, dual solutions are found to exist for the shrinking sheet, whereas the solution is unique for the stretching case.
