ABD-ELAZIZ, M. M.  and  AHMED, S. E.. Group solution for unsteady boundary layer flow of a micropolar fluid near the rear stagnation point of a plane surface in a porous medium. Lat. Am. appl. res. [online]. 2008, vol.38, n.2, pp.161-168. ISSN 0327-0793.

The transformation group theoretic approach is applied to the system of equations governing the unsteady boundary layer flow of a micropolar fluid near the rear stagnation point of a plane surface in a porous media. The application of a two-parameter group reduces the number of independent variables by two, and consequently the system of governing partial differential equations with boundary conditions reduces to a system of ordinary differential equations with appropriate boundary conditions. The possible form of potential velocity U_e is derived in steady and unsteady cases. The family of ordinary differential equations has been solved numerically using a fourth-order Runge-Kutta algorithm with the shooting technique. The effect of varying parameters governing the problem is studied.
