Three-Dimensional Micropolar Flow due to a Stretching Flat Surface

A numerical solution of the steady boundary layer equations under sim-ilarity assumptions is obtained for the three-dimensional flow of a micropo-lar fluid over a continuous stretching surface. The case when microrotation vector is zero on the solid surface is considered. Using properly similar-ity variables, the three-dimensional Navier – Stokes equations are reduced to a set of four coupled non-linear ordinary differential equations. A very ef-ficient numerical solution has been used to solve the boundary layer equa-tions and a comparison is made with earlier results for a Newtonian fluid.
